Edge of Appalachia PreserveOH Images

Geological age: ~430 Mya Silurian dolomite (Peebles Dolomite, Wenlockian stage); underlying Ordovician shale and limestone exposed in stream valley bottoms
Epoch: Middle Silurian (Wenlockian)
Native lands: Adena (c. 1000 BC-AD 100) and Hopewell (c. 200 BC-500 AD) cultures with sustained presence in Adams County; Serpent Mound, a 1,348-foot effigy mound whose authorship is debated between Adena (~300 BCE, radiocarbon 2014/2019) and Fort Ancient (c. AD 1000-1550, charcoal 1991), sits on a bluff directly above Ohio Brush Creek 7 miles northeast of the preserve; both the Shawnee Tribe and Eastern Shawnee Tribe of Oklahoma hold formal ancestral connection to the site; the Warrior's Path, a major north-south Indigenous corridor linking the Great Lakes to the Carolinas, passed through the Ohio River corridor here; Shawandasse Tula (Shawanwaki/Shawnee) and Myaamia (Miami) held south-central Ohio; ceded via Treaty of Greene Ville (August 3, 1795); remaining Ohio Shawnee removed west via Treaty with the Shawnee 1831
Displacement & Tenure: Adams County lies entirely within the Virginia Military District, opened to Virginia Continental Army land warrants beginning 1794 under metes-and-bounds survey; Indigenous title extinguished via Treaty of Greene Ville (August 3, 1795), whose Article 3 boundary placed Adams County fully within the ceded territory; approximately 25% of the Virginia Military District was subsequently acquired by 25 individuals through warrant speculation; Adams County organized 1797; The Nature Conservancy began acquiring preserve lands in 1959
Shadow History: Killen Generating Station (closed 2018), situated within the Ohio Brush Creek drainage basin upstream from the Ohio River confluence, discharged coal ash slurry directly into the Ohio River during 2020 ash pond dewatering in more than 30 documented incidents; unlined ash ponds at Killen and J.M. Stuart Station continue to leach arsenic, boron, cobalt, lithium, and molybdenum into the regional aquifer above drinking-water standards; a 1977-79 archaeological survey documented prehistoric occupation at the Ohio Brush Creek-Ohio River confluence at the Killen site before the area was committed to ash disposal

St. Anne's Woods and WetlandsKY Images

Geological age: ~450 Mya Upper Ordovician shale and fossiliferous limestone (Kope Formation, Cincinnatian Series); Ohio River alluvium at site
Epoch: Late Ordovician (Cincinnatian)
Native lands: Adena (c. 1000 BC-100 AD) and Hopewell (c. 200 BC-500 AD) cultures present in Ohio River valley; Fort Ancient culture (c. 1000-1650 AD) maintained villages along the Ohio River and major Northern Kentucky tributaries; Shawandasse Tula (Shawanwaki/Shawnee) ranged through Northern Kentucky as hunting territory in the historic period; Ohio River corridor a contested boundary zone between multiple nations through the mid-18th century; Shawnee ceded regional lands via Treaty of Greene Ville (August 3, 1795)
Displacement & Tenure: Northern Kentucky is outside the federal-domain Royce cession system. Virginia created Kentucky County 1776 and enacted the Virginia Land Act 1779, opening Kentucky to land warrants and grants; Campbell County established 1794; Kentucky statehood 1792; the Congregation of Divine Providence acquired the land c. 1908 and established St. Anne's Convent 1919; the Diocese of Covington purchased the convent building in 2013 while the Campbell County Conservation District purchased the wetlands (165 acres) in September 2013 using a Kentucky Heritage Land Conservation Fund grant; a perpetual conservation easement is held by the Commonwealth of Kentucky
Shadow History: The land was donated in 1909 by Catholic layman Peter O'Shaughnessy to the Sisters of Divine Providence; the prior ownership chain and any antebellum land history remain undocumented in public records.

Red River Gorge Geological AreaKY Images

Geological age: ~310 Mya Pennsylvanian Corbin Sandstone (Grundy Formation, Pottsville Escarpment); deposited in marine and deltaic river delta environments beginning ~340 Mya; prominent iron-oxide Liesegang banding; over 100 natural sandstone arches, highest concentration east of the Mississippi River.
Epoch: Early Pennsylvanian (Morrowan).
Native lands: Paleoindian peoples first documented in gorge rock shelters c. 10,000 BC; continuous occupation through Archaic and Woodland periods (~12,000 years total); 664 known prehistoric and historic sites including some of the earliest evidence of plant domestication in eastern North America; Tsalagi (Cherokee) held eastern Kentucky as territorial range in the historic period; Shawandasse Tula (Shawanwaki/Shawnee) ranged throughout central Kentucky as a shared hunting corridor; Kentucky was contested hunting ground, not permanently settled by any single nation in the historic period; Cherokee ceded eastern Kentucky via Treaty of Hard Labor (October 1768) and Treaty of Lochaber (October 18, 1770); Shawnee resistance continued through the 1790s, with territorial claims extinguished via Treaty of Greene Ville (August 3, 1795).
Displacement & Tenure: Eastern Kentucky is outside the federal-domain Royce cession system. Cherokee ceded eastern Kentucky via Treaty of Hard Labor (October 1768) and Treaty of Lochaber (October 18, 1770), extending the colonial boundary to the Kentucky River; Henderson's Transylvania Purchase (March 17, 1775) from Overhill Cherokee chiefs at Sycamore Shoals asserted private title but was voided by Virginia (1778) and North Carolina; Virginia created Kentucky County 1776 and enacted the Virginia Land Act 1779, opening eastern Kentucky to land warrants and grants; Kentucky statehood 1792; Daniel Boone National Forest lands assembled by USFS via purchase under the Weeks Act beginning 1916; Red River Gorge Geological Area designated by the USFS 1974.
Shadow History: Congress authorized an Army Corps of Engineers dam project on the Red River in 1962 following that year's Great Flood of Clay City; the proposed dam would have flooded 2,100 acres, covering two-thirds of the gorge and destroying more than half of its plant and animal life; Sierra Club-organized opposition mounted a November 18, 1967 Dam Protest Hike through Clifty Wilderness led by Supreme Court Justice William O. Douglas with over 600 participants that drew national press coverage; two separate dam sites were proposed over the following decades; archaeological looting of rock shelters throughout the 20th century destroyed stratigraphic context at sites containing some of the earliest evidence of plant domestication in eastern North America; by 1990 all rock shelters in the gorge containing both white-haired goldenrod and Indian artifacts had been pillaged by looters; Solidago albopilosa was federally listed as threatened in part because looting-related disturbance uprooted the plant's stolons and seeds; the logging-era Nada Tunnel (1910-1912), a 900-foot passage blasted through sandstone for a narrow-gauge railroad, killed at least one worker during construction; the dam controversy concluded December 3, 1993 when President Clinton signed the Red River into the National Wild and Scenic River system.

Epoch: Late Silurian (Ludlovian).
Native lands: Adena (c. 1000 BC-100 AD) and Hopewell (c. 200 BC-500 AD) cultures; Seip lies within the densest 20-mile corridor of Hopewell monumental earthworks on the continent, running from Bainbridge to Chillicothe along the Paint Valley; Chalahgawtha (principal-town) division of the Shawandasse Tula (Shawanwaki/Shawnee) held the Paint Creek valley as the principal Shawnee territorial corridor; documented Chalahgawtha town at Frankfort on Paint Creek in Ross County; Myaamia (Miami) co-held south-central Ohio; Shawnee and Miami lands ceded via Treaty of Greene Ville (August 3, 1795), Article 3 boundary and Article 4 relinquishment; Shawnee removed west via Treaty with the Shawnee 1831 under Indian Removal Act 1830.
Displacement & Tenure: Ceded via Treaty of Greene Ville (1795); Paxton Township lands entered private agricultural ownership under the Virginia Military District land grant system; site farmed throughout the 19th century and embankment walls leveled to approximately 10% of their original extent by agricultural plowing; Ohio Historical Society archaeologist William Mills excavated 1906-1909 under agreement with the private landowner; site donated to Ohio Historical Society by landowner James Seip 1923; added as an authorized unit of Hopewell Culture National Historical Park via Public Law 102-294 (May 27, 1992); full deed transferred to National Park Service October 10, 2014.
Shadow History: William Mills (Ohio Historical Society) excavated three conjoined mounds at Seip 1906-1909, removing 48 burials and artifacts including copper, mica, bone, shell, and pearl objects to the Ohio State Museum in Columbus; Henry Shetrone and Emerson Greenman (Ohio Historical Society) excavated the main Seip Mound over three field seasons 1925-1928, removing 122 burials and elaborate grave goods including Isle Royale copper objects, Carolina mica sheets, five Tennessee effigy pipes known as the Great Pipes, woven milkweed-fiber textiles with preserved geometric designs, and thousands of freshwater pearl beads from a log-lined crypt, all transferred to museum collections in Columbus; farming throughout the 19th and early 20th centuries leveled embankment walls to approximately 10% of their original height before Ohio Historical Society acquisition; earthworks not under full federal protection until NPS deed transfer in 2014; LiDAR analysis has documented old stream channels cutting into original earthwork boundaries, indicating centuries of unmitigated flood erosion.

Rocky Fork State ParkOH Images

Geological age: ~425 Mya Silurian dolomite (Peebles Dolomite, Ludlovian); 75-ft gorge incised approximately 25,000 years ago when advancing Wisconsin glacier ice blocked Rocky Fork Creek's original drainage outlet, reversing stream flow direction and rapidly cutting through dolomite bedrock; carbonate dissolution formed cave systems in the gorge walls; collapsed cave ceilings visible as large slump blocks in the streambed.
Epoch: Middle Silurian (Wenlockian/Ludlovian).
Native lands: Hopewell culture (c. 200 BC-500 AD) constructed at least two ceremonial earthwork complexes within current park boundaries: Rocky Fork Park Site (NRHP 73001479), a double-concentric circular enclosure with gateways on its eastern side, and the Rocky Fork Park Group (NRHP listed 1973), a separate mound group on an adjacent hilledge; both sites were never plowed, preserving their original earthwork profiles; Chalahgawtha (principal-town) division of the Shawandasse Tula (Shawanwaki/Shawnee) used the Paint Creek and Rocky Fork Creek corridors as principal travel routes and considered the Paint Valley home territory; Myaamia (Miami) co-held southern Ohio; Shawnee lands ceded via Treaty of Greene Ville (August 3, 1795), Article 3; remaining Shawnee removed west via Treaty with the Shawnee 1831 under Indian Removal Act 1830.
Displacement & Tenure: Ceded via Treaty of Greene Ville (1795, Article 3), extinguishing Shawnee and Miami title to Highland County; county organized 1805 and entered private agricultural ownership; Rocky Fork Creek valley acquired by Ohio Division of Conservation and Natural Resources for reservoir and recreation development; Rocky Fork State Park established 1950; dam construction began 1951, water first impounded April 1953; Rocky Fork Lake (2,080 acres, 31-mile shoreline, dam 74 ft high and 380 ft long, 30,000 cubic yards of concrete) was constructed strictly for recreational purposes, not flood control; condemnation and flooding of valley-floor agricultural land required displacement of farm families.
Shadow History: Rocky Fork Lake impounded 1951-1953, flooding the Rocky Fork Creek bottomland and requiring condemnation of valley-floor farm properties; the Blue Ribbon Road covered bridge and McCoppin's Mill (in continuous operation since 1829 using water turbines) were among the structures inundated; Rocky Fork Gorge State Nature Preserve (86 acres, Miller Nature Sanctuary), the only state nature preserve in Highland County, was not dedicated until 1982, leaving the gorge corridor without formal protection for nearly 30 years after park establishment; two Hopewell earthwork complexes within park boundaries, Rocky Fork Park Site and Rocky Fork Park Group (NRHP listed 1973), remain without dedicated on-site archaeological interpretation; Rocky Fork Creek biological communities have performed as badly as or worse than at any time since the initial Ohio EPA study in 1991, impaired by agricultural runoff, failing Home Sewage Treatment Systems, and elevated E. coli concentrations.

Hopewell Culture National Historical ParkOH Images

Hopewell Culture National Historical Park I

Geological age: ~375 Mya Devonian shale (Ohio Shale, Olentangy Shale); earthworks built on Pleistocene glacial outwash terraces.
Epoch: Late Devonian.
Native lands: Adena (c. 1000 BC-100 AD) and Hopewell (c. 1 CE-400 AD) cultures constructed the Mound City earthworks; no direct genealogical link between Hopewell builders and any historically documented tribe has been established; Chalahgawtha (principal-town) division of the Shawandasse Tula (Shawanwaki/Shawnee) returned to the Scioto valley c. 1738 following Haudenosaunee dispersal of Shawnee from the region in the 1670s-80s; the Scioto River Chalahgawtha town (c. 1758-1787) stood on the Scioto west bank near Paint Creek approximately 2-3 miles from Mound City, housing approximately 1,200 people including Tecumseh (b. 1768); Chillicothe, meaning principal town of the Chalahgawtha sept, was the moving political capital of the Shawnee nation with multiple documented locations across southern Ohio; Myaamia (Miami) held the Miami River valleys to the west; Shawnee and Miami lands ceded via Treaty of Greene Ville (August 3, 1795), Article 3 boundary and Article 4 relinquishment, with Shawnee receiving $1,000 annual annuity goods; remaining Shawnee removed west via Treaty with the Shawnee 1831 under Indian Removal Act 1830.
Displacement & Tenure: Ceded via Treaty of Greene Ville (1795, Article 3); Mound City tract entered Virginia Military District ownership c. 1796-1798 when frontier land speculator Nathaniel Massie surveyed and acquired the land; Shriver family held title from 1832; Civil War militia used the site as Camp Logan drill ground in 1861; woodland cleared beginning c. 1856 and smaller mounds plowed under during agricultural use; U.S. Army purchased the land in 1917 and established Camp Sherman (construction began June 21, 1917), a 9,700-acre WWI training cantonment built over and around the earthworks, with more than 120,000 soldiers passing through before decommissioning 1921; Ohio Historical Society advocacy resulted in designation as Mound City Group National Monument via Proclamation 1653 (President Warren G. Harding, March 2, 1923) under the Antiquities Act (34 Stat. 225); Hopeton Earthworks added via Public Law 96-607 (1980); redesignated Hopewell Culture National Historical Park via Public Law 102-294 (May 27, 1992), adding Hopewell Mound Group, High Bank Works, and Seip Earthworks; inscribed UNESCO World Heritage Site as Hopewell Ceremonial Earthworks (list no. 1689, criteria i and iii) September 19, 2023.
Shadow History: Squier and Davis opened mounds at Mound City in 1846, recovering approximately 200 stone effigy cremation pipes from Mound 8 (Mound of Pipes), the majority of the collection sent to the British Museum in London where it remains today; Warren K. Moorehead excavated the Hopewell Mound Group using horses and scrapers 1891-1892, obliterating stratigraphic context to collect artifacts for display at the 1893 World's Columbian Exposition in Chicago, where the collection remains at the Field Museum; U.S. Army construction at Camp Sherman 1917 demolished virtually all mounds at Mound City except the large central Mound 7 to grade barracks, roads, pipelines, and railroad lines; mounds #13 and #23 were specifically cut down; excavation of the destroyed Mound 13 base in 1921 recovered cremated remains of 20 Hopewell individuals and a mica-lined grave representing only what was preserved at the base level, with all upper-context material permanently destroyed; artifacts unearthed during Army construction were taken as military souvenirs; the 813th Pioneer Infantry and other African American segregated units of the 92nd Division trained at Camp Sherman under white officers per Army policy; 1,777 soldiers died of influenza at Camp Sherman during the 1918 pandemic, with 125 deaths in a single day on October 9, 1918, and approximately 60% of Chillicothe's civilian population infected; all leveled mounds were reconstructed by Ohio Historical Society from the 1846 Squier-Davis survey maps, the original fill and artifact context permanently destroyed.

New River Gorge National Park and PreserveWV Images

New River Gorge National Park and Preserve I

Geological age: ~325 Mya Pennsylvanian and Mississippian sandstone, shale, and coal seams.
Epoch: Pennsylvanian (Carboniferous).
Native lands: Shawnee (Shawanwaki) and Cherokee (Aniyvwiya) maintained hunting territories throughout the New River drainage; Shawnee forces under Chief Cornstalk fought Virginia militia at the Battle of Point Pleasant (October 10, 1774), a decisive engagement leading to the Treaty of Camp Charlotte (October 19, 1774), in which the Shawnee agreed to cease hunting south of the Ohio River and recognize Virginia's territorial claims; Seneca (Onöndowa'ga:') of the Haudenosaunee Confederacy maintained the Seneca Trail corridor (present US-219) through the region; Moneton peoples documented in pre-contact archaeological evidence; more than 400 archaeological sites along the New, Gauley, and Bluestone Rivers record at least 11,000 years of continuous Indigenous occupation; Shawnee removal to Oklahoma completed under federal pressure by the post-Civil War era.
Displacement & Tenure: New River Gorge area was part of Virginia's colonial charter (1609) and not included in the Virginia Cession of 1784 to the federal government; lands remained under private Virginia and later West Virginia (statehood June 20, 1863) ownership through coal and timber grants; federal acquisition began when Congress established New River Gorge National River (November 10, 1978, Pub. L. 95-625), with NPS purchasing coal and timber company lands through the 1990s; designated National Park and Preserve December 27, 2020.
Shadow History: The gorge's coal company towns enforced a scrip economy in which workers were paid in currency redeemable only at company stores, with markups ensuring perpetual indebtedness; armed guards controlled movement in and out of gated communities. African American miners comprised more than 25% of West Virginia's mining workforce by 1909; Helen, WV (developed by East Gulf Coal Company) enforced strict residential and educational segregation above ground while Black and white workers received equal wages for equal work underground; NPS documents segregated housing, schools, and churches at Nuttallburg and Helen. Coal processing operations associated with the gorge's mines introduced heavy metals into New River tributaries, a pattern documented across the Appalachian coalfield. Segregated CCC companies operated in the region 1933-1942 following Director Robert Fechner's 1935 segregation order.

Big Bone Lick State Historic SiteKY Images

Geological age: ~450 Mya Ordovician limestone and shale (Kope Formation); Pleistocene fossil-bearing bog deposits (25,000-12,000 BP).
Epoch: Late Ordovician (Cincinnatian Series); late Pleistocene (Wisconsinan Glaciation).
Native lands: Paleoindians from at least ~12,000 BP · Shawnee (Shawanwaki) · Delaware (Lenape); the salt springs drew Indigenous hunters for millennia; Shawnee used the lick as a salt source and hunting ground; Mary Draper Ingles, captured by Shawnee in 1755, was brought to Big Bone Lick and put to work boiling brine; Iroquois Confederacy ceded their Ohio River corridor claim to the British Crown via Treaty of Fort Stanwix 1768, a transaction the Shawnee disputed; Shawnee ceded rights south of the Ohio under duress via Treaty of Camp Charlotte 1774 ending Lord Dunmore's War; Cherokee ceded overlapping claims via Treaty of Sycamore Shoals 1775, a private purchase nullified by Virginia 1778; two prehistoric burial mounds and a cemetery documented by the 1932 Webb-Funkhouser survey; 2008 excavation found possible cut marks on Pleistocene bones suggesting Paleoindian butchering.
Displacement & Tenure: Kentucky was organized as a Virginia county in 1776 and was never part of the federal public domain; no federal Royce cession applies; Iroquois Confederacy ceded British Crown claim to lands south of the Ohio via Treaty of Fort Stanwix (1768), disputed by the Shawnee; Shawnee ceded rights south of the Ohio via Treaty of Camp Charlotte (1774); Cherokee claim extinguished via Treaty of Sycamore Shoals (1775), voided by Virginia 1778; Kentucky distributed as Virginia military bounty land grants prior to statehood 1792; the Big Bone Lick Historical Association purchased 16.66 acres and deeded them to the Kentucky State Commissioner for conservation, with the park formally established July 2, 1960.
Shadow History: Big Bone Lick has been systematically stripped of paleontological material for nearly 300 years. In 1739, French-Canadian military commander Charles Le Moyne de Longueuil collected a tusk, femur, and molars and shipped them to Paris, where they entered Louis XV's Cabinet du Roi under Buffon's direction, initiating the first scientific attention to North American Pleistocene megafauna. In 1765-66, British Indian agent George Croghan extracted specimens on two expeditions; one collection was seized during an attack; the second was presented by Benjamin Franklin to the Royal Society of London. By the late 18th century, hundreds and possibly thousands of bones had been removed by collectors. President Thomas Jefferson, fixated on the site as a rebuttal to Buffon's theory of American animal degeneracy, dispatched Meriwether Lewis in October 1803 to collect specimens; those bones were loaded onto a keelboat and shipped south from Fort Mandan in spring 1804 and the boat sank near Natchez, Mississippi, losing the entire collection. Jefferson then commissioned William Clark, who conducted a three-week excavation in fall 1807 with a ten-man crew, removing over 300 bones and teeth; Jefferson divided the collection among the Paris Museum of Natural History, the American Philosophical Society, and Monticello, where specimens were displayed in the Entrance Hall. Clark's 11-page description allowed naturalists to distinguish mammoths from mastodons for the first time, making this the first funded paleontological field excavation in North America. In 1962-67, University of Nebraska paleontologists recovered over 2,000 specimens now held at the University of Nebraska State Museum; four species were formally named from Big Bone Lick material. James Colquohoun operated a salt works at the site from approximately 1795 until 1812; Kentucky salt works of the era routinely used enslaved labor, and the 1800 Boone County census recorded 325 enslaved persons (21% of the county population), though direct documentary evidence tying enslaved workers to Colquohoun's operation has not yet been confirmed in available records. The Clay House hotel opened at Big Bone Lick in 1815 and operated until approximately 1845, serving planter families including the Clays and Breckinridges for mineral spring bathing; enslaved domestic service workers almost certainly staffed the operation, but no named records have been located.

Dinsmore Woods State Nature PreserveKY Images

Geological age: ~450 Mya Ordovician limestone and shale.
Epoch: Late Ordovician (Cincinnatian Series); Kope, Fairview, and Bull Fork formations.
Native lands: Adena culture (500 BCE-200 CE) · Shawnee (Shawanwaki) · Cherokee (Tsalagi); Adena moundbuilding culture occupied the Ohio River valley with documented sites in Boone County; Kentucky's interior served as contested hunting ground at the time of European contact; Iroquois Confederacy ceded their Ohio River corridor claim to the British Crown via Treaty of Fort Stanwix 1768; Cherokee ceded approximately 20 million acres including present-day Kentucky to the Transylvania Company via Treaty of Sycamore Shoals March 1775, opposed by Cherokee leader Dragging Canoe who called the cession a betrayal and withdrew to form the Chickamauga; Shawnee recognized the Ohio River as their southern boundary under Treaty of Camp Charlotte 1774, though many Shawnee rejected this cession; Shawnee and allied nations formally ceded remaining Ohio Valley claims via Treaty of Greenville 1795.
Displacement & Tenure: Shawnee territory recognized as south of the Ohio River under Treaty of Camp Charlotte (1774), though many Shawnee rejected this cession; Cherokee claim extinguished via Henderson Purchase (Treaty of Sycamore Shoals, 1775), voided by Virginia 1778; Iroquois claim to the Ohio River valley ceded to the British Crown via Treaty of Fort Stanwix 1768; northern Kentucky distributed as Virginia military bounty land grants prior to Kentucky statehood 1792; no federal Royce cession applies; the Dinsmore Woods parcel was part of approximately 700 acres purchased by James and Martha Dinsmore in 1839; Martha Munro Ferguson Breasted, a Dinsmore descendant, donated 107 acres to The Nature Conservancy in 1985; dedicated as a Kentucky State Nature Preserve May 16, 1990; Boone County purchased the preserve from the Conservancy using Kentucky Heritage Land Conservation Fund proceeds in November 2010.
Shadow History: The 107-acre nature preserve is the forested portion of the original Dinsmore farm, a working plantation on which enslaved people lived and labored from 1842 onward. James Dinsmore brought approximately 20-25 enslaved individuals from his Mississippi and Louisiana holdings to Kentucky upon completing Dinsmore Homestead in 1842. Those documented by name include: Coah (ca. 1790-1862), born in West Africa and previously enslaved in Mississippi and Louisiana; Nancy McGruder (ca. 1809-1906), purchased by Dinsmore in 1828 in Mississippi; Sally Taylor (ca. 1810-?) and her children John, Daniel, David, Nannette, Judy, Angeline, and Isaac; Jilson Hawkins (ca. 1811-1879) and Eliza Hawkins (ca. 1819-1903). Nancy McGruder left the farm after the Civil War's end, then returned to work as a free person, living on the property until her death in 1906. The Dinsmore Homestead, listed on the National Register of Historic Places, installed interpretive panels documenting the African American experience on the farm from 1840 through 1865. The woodland tract that became the nature preserve was inseparable from this farm landscape; no public interpretation at the preserve connects the old-growth forest to the labor history of the people who lived among it.

Caesar Creek State ParkOH Images

Geological age: ~447 Mya Ordovician limestone and shale.
Epoch: Late Ordovician (Cincinnatian Series); Waynesville, Liberty, and Whitewater formations.
Native lands: Shawnee (Shawanwaki) · Myaamia (Miami) · Hopewell culture (300 BCE-600 CE) · Fort Ancient culture (1200-1600 CE); Fort Ancient Earthworks, a UNESCO World Heritage Site, located in Warren County; creek named for Caesar, an enslaved Virginian who escaped bondage c. 1774, was adopted by the Shawnee, and used the valley as hunting grounds; Shawnee and Miami ceded southern Ohio via Treaty of Greenville 1795; remaining Ohio Shawnee removed west via Treaty of Wapakoneta 1831.
Displacement & Tenure: Cession 11: Treaty of Greenville (1795); U.S. Army Corps of Engineers began acquiring Caesar Creek Valley land in the mid-1960s under eminent domain authority of the Flood Control Act of 1938; construction started 1971, dam completed 1978; village of New Burlington condemned and inundated, approximately 300 residents displaced involuntarily; last resident departed April 20, 1973; state park opened 1978, managed by Ohio DNR under lease from the Army Corps.
Shadow History: The creation of Caesar Creek Lake required the forced inundation of New Burlington, a functioning rural community straddling the Warren/Clinton County line at the confluence of Caesar Creek and Anderson Fork. Approximately 300 residents were displaced beginning in the mid-1960s when the Army Corps of Engineers began acquiring land under eminent domain; the last resident, 87-year-old Lawrence Mitchner, departed April 20, 1973, after refusing to meet with Corps appraisers. The community included a post office, Quaker meetinghouse, school, churches, a Masonic lodge, and farms. John Baskin documented the displacement in New Burlington: The Life and Death of an American Village (1976). The Caesar's Creek Quaker Meetinghouse was relocated rather than demolished. A 1976 archaeological reconnaissance conducted prior to inundation documented pre-contact sites in the reservoir footprint; earlier surveys had recorded a Hopewell-era village of 60-70 acres near the creek, featuring burial mounds up to 8 feet high with 79 documented burials; these and other sites were permanently inundated without preservation. The creek's name carries an additional layer: it memorializes Caesar, an enslaved Virginian who escaped bondage c. 1774 and was adopted into the Shawnee nation, a detail absent from most park signage.

Shawnee LookoutOH Images

Geological age: ~450 Mya Ordovician limestone and shale.
Epoch: Late Ordovician (Cincinnatian Series); Waynesville and Arnheim formations.
Native lands: Adena culture · Hopewell tradition · Fort Ancient culture · Shawnee (Shawanwaki) · Myaamia (Miami); site occupied continuously for approximately 14,000 years; Hopewell builders constructed the Miami Fort earthwork complex approximately 2,000 years ago -- a water management and ceremonial enclosure nearly 6 km in extent, the largest of its kind in Ohio; Fort Ancient culture succeeded Hopewell occupation; Shawnee cultural continuity with the earthwork builders documented by University of Cincinnati archaeologists; the Treaty of Fort Finney (January 31, 1786) was signed at Fort Finney, a U.S. military post erected at the mouth of the Great Miami River directly below the Miami Fort earthwork; Shawnee delegates were coerced under military threat; the broader Shawnee nation repudiated the treaty, triggering the Northwest Indian War; full cession came via Treaty of Greene Ville 1795 following Battle of Fallen Timbers 1794.
Displacement & Tenure: Cession 11: Treaty of Greene Ville (1795); land acquired by Hamilton County Park District (founded 1930), later Great Parks of Hamilton County; Shawnee Lookout Golf Course operated 1979-2019 on portions of the Shawnee Lookout Archaeological District.
Shadow History: The Shawnee Lookout Archaeological District was listed on the National Register of Historic Places in 1974 (NRHP #74001516), recognizing it as one of the most significant Native American hilltop sites in the eastern United States; the listing did not prevent the Hamilton County Park District from constructing the Shawnee Lookout Golf Course in 1979 directly over portions of the archaeological district, burying more than 9,000 feet of headwater streams in culverts and grading land across an active site of national significance; cart paths were laid across the earthwork landscape; the golf course operated until 2019. University of Cincinnati archaeologist Ken Tankersley's fieldwork in 2008-2009 revealed via LiDAR survey that the Miami Fort earthwork complex is approximately twice the size recorded by the standard 19th-century maps, suggesting that major portions of the site were unmapped, unprotected, and potentially altered for over 150 years. The foundational documentation of the site came from E.G. Squier and Edwin Davis's 1847-1848 survey, published as the Smithsonian's first monograph, Ancient Monuments of the Mississippi Valley (1848); in the course of that survey Squier and Davis collected more than 6,000 objects from Ohio Valley mounds and enclosures; Squier sold the collection to a British collector in 1864 for $10,000, and it was transferred to the British Museum in 1931, where it remains today; which objects originated at Miami Fort specifically has not been confirmed in accessible public records. Stream daylighting and archaeological district restoration began 2025 in partnership with The Nature Conservancy, with the Miami Tribe of Oklahoma's Tribal Historic Preservation Office actively consulted on the identification of intact sites and sacred areas.

Fernald PreserveOH Images

Geological age: ~450 Mya Ordovician limestone and shale.
Epoch: Late Ordovician (Cincinnatian Series).
Native lands: Myaamia (Miami) · Shawnee (Shawanwaki) · Fort Ancient culture (900-1650 CE); Great Miami River valley a core Myaamia territory, river named for the nation; Fort Ancient people, widely regarded as Shawnee ancestors, occupied bluffs above the river; Shawnee and Miami among signatories who ceded southwestern Ohio via Treaty of Greene Ville 1795 following Battle of Fallen Timbers 1794; Myaamia removed to Kansas then Indian Territory (present-day Oklahoma) by 1846.
Displacement & Tenure: Cession 11: Treaty of Greene Ville (1795); Atomic Energy Commission condemned and acquired the 1,050-acre Fernald tract in 1951 from eleven private landowners at $375-$652 per acre; three owners who refused sale were dispossessed via federal court condemnation decree April 24, 1951; AEC transferred management to the Department of Energy; site decommissioned 1989; cleanup completed 2006; transferred to DOE Office of Legacy Management November 17, 2006; opened as Fernald Preserve 2007.
Shadow History: From 1951 to 1989 the site operated as the Fernald Feed Materials Production Center (FMPC), a classified uranium metal refining plant processing ore for the U.S. nuclear weapons program under the Atomic Energy Commission and later the Department of Energy; operated by National Lead Company of Ohio 1951-1986, then Westinghouse; produced approximately 170,000 metric tons of uranium metal products over 38 years. DOE and its contractors concealed ongoing contamination from residents for decades: uranium dust was released into air and groundwater throughout the 1950s-1980s; DOE knew by 1980 that private wells near the site were contaminated with uranium but did not disclose this to residents for four years. In 1984 a broken filtration system released approximately 275 pounds of uranium oxide dust off-site. K-65 silos on the site's western end stored radium-226-contaminated waste from uranium ore residues, a persistent source of radon gas; NIOSH documented elevated lung cancer risk among workers exposed to the K-65 radon plume. In 1984 Lisa Crawford, a renter on adjacent property who discovered her well was contaminated, founded Fernald Residents for Environmental Safety and Health (FRESH) and sued the Department of Energy that same year. Also in 1984, pipefitter David Bocks, 39, disappeared during a night shift; his remains were found in a uranium oxide furnace operating at 1,350 degrees; OSHA investigation ruled the death accidental, but coworkers and family disputed this, alleging he had documented plant emissions violations before his death; the case was cited in federal congressional testimony on contractor conduct at DOE weapons facilities. A class-action lawsuit (In re Fernald Litigation, Case No. C-1-85-149) produced a 1989 settlement of $78 million for 9,764 residents within five miles, covering emotional distress, property value loss, and an 18-year medical monitoring program (1990-2008); documented outcomes in the cohort included elevated rates of kidney and urinary tract cancers, lupus, and renal disease. In 1994, plant workers won a separate $20 million settlement for emotional distress and lifetime medical monitoring. EPA designated Fernald a Superfund priority in 1989; cleanup cost $4.4 billion over fifteen years, entombing more than 925,000 cubic yards of low-level radioactive waste under eight capped on-site disposal cells beneath a permanent mound. Uranium contamination of the Great Miami Buried Valley Aquifer was confirmed; pump-and-treat groundwater remediation begun in 1993 continues, with monitoring expected into the late 2030s. The site is permanently restricted from residential use by institutional controls.

Clifty Falls State ParkIN Images

Geological age: ~445 Mya Ordovician limestone and shale.
Epoch: Late Ordovician; Dillsboro Formation (shale and limestone) on lower canyon slopes; Saluda Formation (limestone and dolomite) capping waterfall crests and upper cliffs.
Native lands: Shawandasse Tula (Shawnee) · Myaamia (Miami); Ohio River valley ancestral Shawnee homeland; Shawnee displaced from the Ohio valley following the American Revolution; Treaty of Greenville 1795 ceded southeastern Indiana to the United States; Shawnee, Miami, and allied nations removed from Indiana under the Indian Removal Act 1830.
Displacement & Tenure: Cession 56: Treaty with the Delawares, Pottawatimies, Miames, Eel River, and Weas (1805); 570-acre core acquired October 27, 1920 via joint purchase by Jefferson County citizens and the State of Indiana, initiated by state parks director Richard Lieber; Madison State Hospital transferred adjacent farm fields to the park in 1965, expanding total acreage to approximately 1,416 acres.
Shadow History: Madison State Hospital (opened 1910 as Southeastern Indiana Hospital for the Insane) operated the adjacent farm fields under a patient-labor model in which psychiatric patients grew food, ran a dairy, and built roads without compensation; the Indiana legislature determined in the 1960s that this constituted indentured servitude, leading the hospital to discontinue farming rather than pay patients; the farm fields transferred to the park in 1965 were worked under this system for at least four decades; an institutional cemetery on hospital grounds holds an estimated 300 to 400 burials, the majority marked only with metal crosses bearing patient numbers rather than names.

French ParkOH Images

Geological age: ~450 Mya Ordovician limestone and shale.
Epoch: Late Ordovician (Cincinnatian Series).
Native lands: Hopewell tradition · Shawnee (Shawanwaki) · Myaamia (Miami); Benham Mound, an 8-foot Hopewell burial mound within the park with recovered mica indicating long-distance trade networks, listed on the National Register of Historic Places 1974; Adena culture earthworks documented throughout Hamilton County; Shawnee and Miami held the Ohio River valley at European contact; ceded Ohio lands via Treaty of Greenville 1795 following Battle of Fallen Timbers 1794.
Displacement & Tenure: Cession 11: Treaty of Greene Ville (1795); former 275-acre estate of Herbert Greer French, bequeathed to the Cincinnati Park Board upon French's death in 1942, including the brick manor house; land was part of the John Cleves Symmes Congressional land purchase of the 1790s.
Shadow History: The Benham Mound within the park, a Hopewell burial mound listed on the National Register of Historic Places in 1974, was excavated by local residents in the late 19th century; the diggings recovered mica deposits, stone tools, axes, scrapers, chisels, and flint projectile points; no institutional repository for the recovered material and no record of human remains from these excavations have been identified in accessible records; Herbert Greer French, who bequeathed the estate to the Cincinnati Park Board in 1942, was a vice president of Procter and Gamble.

Big South Fork National River and Recreation AreaTN Images

Big South Fork National River and Recreation Area I

Geological age: ~310 Mya Pennsylvanian sandstone and conglomerate.
Epoch: Pennsylvanian.
Native lands: Cherokee (Aniyunwiya) held the Cumberland Plateau as ancestral hunting territory, with rockshelter camps documented throughout the gorge zone; Yuchi (Tsoyaha) occupied the plateau prior to Cherokee dominance; Shawnee (Shawanwaki) used the region as hunting grounds following the Beaver Wars in the 1660s; Cherokee ceded adjacent plateau lands via the First Treaty of Tellico 1798 and remaining Cumberland Plateau territory via the Third Treaty of Tellico 1805; Cherokee removed to Oklahoma via the Trail of Tears 1838-1839.
Displacement & Tenure: Cession 57: Treaty with the Cherokee (1805); established by the Water Resources Development Act of 1974 (P.L. 93-251); Army Corps of Engineers began acquisition in 1979 across approximately 125,000 acres; Stearns Coal and Lumber Company had conveyed surface rights on 46,842 acres to the United States by deed in 1937 while retaining mineral rights; litigation over whether retained mineral rights authorized strip mining on federal surface produced United States v. Stearns Coal and Lumber Co., 816 F.2d 279 (6th Cir. 1987), affirming that the 1937 deed's silence on strip mining did not permit destruction of the conveyed surface.
Shadow History: Abandoned surface and deep coal mines throughout the park, the highest concentration of any NPS unit in the region, produce ongoing acid mine drainage; Roaring Paunch Creek and multiple tributaries carry contamination the NPS characterizes as potentially harmful to humans, with remediation underway under the Infrastructure Investment and Jobs Act; when word spread that the Army Corps of Engineers was authorized to acquire land under the 1974 act, large private landholders including Stearns Coal and Lumber accelerated logging and mining operations on their holdings before condemnation could proceed, extracting maximum value from land they knew would be taken; Blue Heron, the last Stearns company town in the gorge, was abandoned in 1962 after coal reserves were exhausted, leaving residents to relocate independently before Corps acquisition began in 1979.

Displacement & Tenure: Cession 478: Treaty with the Comanche and Kiowa (Little Arkansas Treaty, 1865); Cession 511: Agreement with the Comanche, Kiowa, and Apache (Jerome Agreement, 1892, ratified 1900); on September 28, 1874, Col. Ranald Mackenzie's troops entered Palo Duro Canyon at dawn, destroyed the winter encampments of Kiowa, Comanche, and Cheyenne bands, and slaughtered approximately 1,000 captured horses, breaking organized resistance; the canyon passed to private ranching, most prominently the JA Ranch established by Charles Goodnight and John Adair in 1876; approximately 15,000 acres purchased in 1933 from Fred A. Emery using a Federal Reconstruction Finance Corporation loan; the park was developed 1933 to 1937 by seven companies of the Civilian Conservation Corps.
Shadow History: CCC Companies 2875 and 2876, composed of African American enrollees transferred from East Texas, arrived at Palo Duro in August 1935 and performed the same construction labor as four white companies already on site; the Texas State Parks Board chairman selected Palo Duro specifically for Black enrollees because its canyon location 13 miles from Amarillo made geographic isolation easier to enforce; Black Texans were legally barred from entering the park they built until the Texas State Parks system was desegregated under federal pressure in 1964; Texas Parks and Wildlife acknowledges that most of the canyon's archaeological sites have been picked over and many artifacts removed.

Displacement & Tenure: Cession 11: Treaty of Greene Ville (1795); core land donated to the State of Ohio in 1937 by Hugh Taylor Birch, who acquired approximately 160 acres adjacent to John Bryan State Park; upper gorge designated a State Nature Preserve in 1973; eight acres listed as a National Natural Landmark in 1967.
Shadow History: The gorge corridor supported six operating mills within one mile by the early 19th century, all functioning before child labor and workplace safety laws; Hugh Taylor Birch, who donated 160 acres to the state in 1937 and also donated the initial parcel of Glen Helen to Antioch College in 1929, was an attorney and real estate speculator who assembled multiple large tracts in the Little Miami corridor; no records of displaced tenants in either acquisition appear in accessible archives.

Parker WoodsOH Images

Geological age: ~450 Mya Ordovician shale and limestone (Kope Formation).
Epoch: Late Ordovician (Cincinnatian Series).
Native lands: Shawnee (Shawanwaki) · Myaamia (Miami) · Adena and Hopewell moundbuilder cultures; Cincinnati area a major nexus of Shawnee and Miami territory; Fort Washington established 1789 as U.S. military base on Shawnee lands; Shawnee and Miami among signatories ceding southern Ohio via Treaty of Greenville 1795 following Battle of Fallen Timbers 1794.
Displacement & Tenure: Cession 11: Treaty of Greene Ville (1795); the Langland family held the property from their original 266-acre farm purchase in 1822; Margaret Parker and her children sold the initial 27.5 acres to the City of Cincinnati in 1911 for $41,233.50, with the park named for Alexander Langland Parker; a second parcel added in 1953.
Shadow History: The park sits adjacent to the Mill Creek watershed, which a 1996 assessment found to contain three Superfund sites on its banks, 31 other hazardous waste sites, and 158 combined sewer overflow outflows; EPA conducted a buried-drum hazardous waste removal on the West Fork Mill Creek in South Cumminsville in 2004; no contamination record specific to the Parker Woods parcel has been located, though the Mill Creek corridor has been among the most industrially contaminated urban streams in the Midwest.
Acreage: ~63 acres

Glen Helen Nature PreserveOH Images

Geological age: ~445-430 million years ago (bedrock); gorge and ravine system formed by glacial meltwater ~15,000 years ago.
Epoch: Silurian period (Llandovery-Wenlock); same dolomite and limestone formations as Clifton Gorge; Holocene iron precipitation at Yellow Spring actively ongoing ; visible as orange mineral staining on rock surfaces.
Native lands: Shawnee (Shawanwaki) · Miami · Adena culture; Orators Mound (Adena burial mound) within preserve boundaries; Yellow Spring a known Shawnee waypoint; Little Miami River a principal Shawnee waterway.
Displacement & Tenure: Cession 11: Treaty of Greene Ville (1795); attorney Hugh Taylor Birch donated the initial 700-acre parcel to Antioch College in 1929 as a memorial to his daughter Helen Birch Bartlett; Glen Helen Association assumed operational ownership from Antioch College in 2020 via a $2.5 million agreement over ten years.
Shadow History: Frank Van Wort partially excavated the Orators Mound within the preserve in 1953 to 1954, finding five skeletons (two adults, three infants) and placing seven skeletons along with artifacts in the Dayton Museum of Natural History; Van Wort published no reports; the current location or repatriation status of this material is not confirmed in available sources; a 1971 Antioch College excavation under archaeologist Wolfgang Marschall identified the mound as Hopewellian; the Neff family's 246-room hotel at the Yellow Spring, built in 1869 at a cost of approximately $250,000 and targeting Southern vacationers, failed financially within 13 years.

Otto Armleder Memorial ParkOH Images

Geological age: ~450 million years ago (Ordovician bedrock); floodplain deposits Holocene.
Epoch: Ordovician period (Cincinnatian); overlain by Quaternary glacial outwash and Holocene alluvium; site lies on Little Miami River floodplain shaped by Wisconsin glaciation meltwater.
Native lands: Shawnee (Shawanwaki) · Fort Ancient culture (900-1650 CE); Little Miami River a principal Shawnee corridor; Shawnee ceded Ohio lands via Treaty of Greene Ville 1795.
Displacement & Tenure: Cession 11: Treaty of Greene Ville (1795); the Little Miami floodplain site remained largely undeveloped due to periodic flooding; the park was funded through the Otto Armleder Trust, established by the 1935 will of Cincinnati businessman Otto Armleder (1862 to 1935), directing his estate toward charitable and civic projects in Hamilton County.
Shadow History: Ohio EPA and USGS assessments of the Little Miami basin have documented elevated trace elements and synthetic organic compounds including organochlorine insecticides and PCBs in streambed sediments downstream of Cincinnati's industrial corridor; no Superfund listing specific to the Armleder floodplain section appears in EPA records; the park's floodplain location, which prevented prior development and made acquisition relatively inexpensive, reflects the same industrial contamination history that kept the land undeveloped.
Acreage: 347 acres

Bender Mountain Nature PreserveOH Images

Geological age: ~450 million years ago (Ordovician bedrock); ridge morphology shaped by Illinoian glaciation ~400,000 years ago.
Epoch: Ordovician period (Cincinnatian); Ohio River rerouted during Illinoian glaciation created oversteepened valley walls; Pleistocene colluvium mantles bedrock slopes.
Native lands: Shawnee (Shawanwaki) · earlier Adena and Hopewell peoples; Ohio River ridge a known travel and hunting corridor; Shawnee ceded Hamilton County lands via Treaty of Greene Ville 1795.
Displacement & Tenure: Cession 11: Treaty of Greene Ville (1795); established in 2003 through Clean Ohio conservation program funds and Great Parks of Hamilton County ForeverGreen funding; in 2023 the Sisters of Charity of Cincinnati donated 73 acres to the Western Wildlife Corridor, the largest single gift in that organization's history.
Shadow History: Prior land use included grazing, hog foraging, fruit growing, and selective logging; no quarrying, industrial use, or documented forced removal has been identified for this Ohio River bluff site in accessible records; the Western Wildlife Corridor began managing the site in 2003 and describes it as degraded agricultural and silvicultural land undergoing active restoration.
