An outcrop of the Black Hand Sandstone Member of the Cuyahoga Formation at the Conkle's Hollow State Nature Preserve area in Hocking Hills State Park, Hocking County, Ohio. Conkle's Hollow is a deep rocky gorge. All three zones of the Black Hand Sandstone are visible in the steep cliffs of the valley walls. Crossbedding and honeycomb weathering are well displayed on the fretted surface of the Black Hand. The gorge at Conkle's Hollow follows a major joint trending N 60° W. Conkle's Hollow is named for an early visitor who inscribed his name, W. J. Conkle 1797, on the west wall of the gorge. Bedrock is from the Mississippian Geologic Period. The photograph was taken by Guy L. Denny in July 1966.
