Description
The rock outcrops, which can be seen throughout Conkle's Hollow, are comprised entirely of Black Hand sandstone; a sandstone formation extending in a narrow band from the Ohio River, northward nearly to Lake Erie in eastern Ohio. The Black Hand sandstone is divided into three layers. The top and bottom layers are strongly cemented together while the middle layer is much softer and erodes much easier. It is in this softer portion of the Black Hand sandstone that recesses or re-entrant caves often form. The yellow, orange and red colors on the rock are evidence of the iron oxide which binds the sand grains together.
