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.
Ecology Mixed mesophytic forest with oak-hickory woodlands, beech-maple slopes, and pawpaw thickets; meadow and prairie patches support pollinators; creek corridor hosts sycamore and tulip-poplar with exposed Ordovician fossil beds.
Hydrology Amberley Creek flows through the park, a tributary of Mill Creek, which drains 166 square miles of Hamilton County to the Ohio River; creek bed exposes fossiliferous Ordovician limestone.
