This is a piece of Black Hand sandstone. Black Hand Sandstone makes up many of Ohio's geological features, including Old Man's Cave, Cedar Falls, and Rock House in Hocking Hills. Named after an Indigenous petroglyph of a black hand in Black Hand Gorge near Newark, Black Hand Sandstone "is a coarse, sometimes conglomeratic quartz sandstone […and is] massive in nature, without many discrete beds or major changes in its consistency" ("Blackhand Gorge"; Hartshorn). Covering a range of colors from red to brown to cream, Black Hand sandstone "forms sheer cliffs and gorges" and often features waterfalls (United States Geological Survey; "Black Hand Sandstone"). Additionally, it may show "cross-bedding, the angled bedding of ancient ripples or dunes, and graded beds, where layers of coarse pebbles transition upward into layers of smaller pebbles and then into the sand, an indication of sorting by water" (Hartshorn).Location
