A photograph of the location for the abandoned Lewis mine slopes in Weathersfield Township, Trumbull County, Ohio. The Lewis mine was a subsurface mining operation for the Sharon (No. 1) coal. This location is where coal was first discovered on that side of the Ridge. The slopes are covered in the photograph, but it is near them that the active drain for the Ridge is found as a bubbling spring. The area of the mine has shale, siltstone, sandstone, conglomerate, limestone, underclay, coal and flint lithologies. Bedrock is from the Pennsylvanian Geologic Period. The photograph was taken during the summer field work of James Osborn Fuller and Myron T. Sturgeon in July 1941.
The Lower Falls at Hocking Hills State Park, Hocking County, Ohio. Downstream from Old Man's Cave, Old Man's Creek encounters the resistant lowermost zone of the Black Hand Sandstone and cascades into a broad plunge pool as a scenic waterfall known as the Lower Falls. A large rock shelter is developed behind the waterfall. At the base of the rock shelter the contact between the Fairfield Shale and the Black Hand Sandstone Members of the Cuyahoga Formation can be seen. Bedrock is from the Mississippian Geologic Period. This photograph was an entry in the 1983 Ohio Geology Slide Contest.
Black Hand Sandstone rises 150 feet from the valley floor overlooking Laurel Run. Halfway up the face of the cliff is a row of five to seven
An outcrop of Black Hand Sandstone of the Cuyahoga Formation at Crane Hollow State Nature Preserve. Jane Ann and William Ellis organized Crane Hollow, Inc., in 1980 as a private, non-profit corporation that owns and administers the Crane Hollow Nature Preserve. The preserve encompasses more than 1,940 acres in Hocking County, Ohio. Access is by permit only to the 1,286 acres dedicated as a state nature preserve with the Ohio Department of Natural Resources, Division of Natural Areas and Preserves. Crane Hollow State Nature Preserve is part of the unglaciated Allegheny Plateau, with elevations from 780 feet to 1,140 feet. Bedrock is from the Mississippian Geologic Period.
Trails leading through the Lower Gorge come to Queer Creek and eventually to Cedar Falls at Hocking Hills State Park, Hocking County, Ohio. Cedar Falls is a semi-circular cliff over which Cedar Creek flows to form a waterfall, 50 feet in height. Behind the falls is a small recess cave formed by the sapping action of the plunge pool. The face of the waterfall is crossed by two deep grooves, formed by the abrasive action of small sand particles, through which the water flows. The rim of Cedar Falls is composed of the hard, massive upper layer of the Black Hand Sandstone. Two joint fractures are readily visible in the upper zone
A scenic view of Rockbridge at Rockbridge State Nature Preserve in Hocking County, Ohio. The image was taken by Michael C. Hansen in 1973. The Natural Arch and Bridge Society defines a natural arch as �a rock exposure that has a hole completely through it formed by the natural, selective removal of rock, leaving a relatively intact frame.� At 92 feet Rockbridge is Ohio's longest natural bridge. The bridge originated as a typical Hocking Hills alcove carved into the soft middle layer of Black Hand Sandstone at the head of a short box canyon cut by a small tributary of the Hocking River. Three intersecting vertical fractures in the roof of the shelter were gradually enlarged until the block they surrounded was no...
Conkles Hollow Arch is a natural arch of resistant Mississippian Geologic Period Black Hand Sandstone in Conkle�s Hollow State Nature Preserve, Hocking County, Ohio. The Natural Arch and Bridge Society defines a natural arch as �a rock exposure that has a hole completely through it formed by the natural, selective removal of rock, leaving a relatively intact frame.�
A filled shaft at the abandoned Mahoning Coal Company No. 4 slope mine near Coalburg in Hubbard Township, Trumbull County, Ohio. The Mahoning Coal Company No. 4 mine was part of the Sharon (No. 1) coal subsurface mining operation in the Vienna-Coalburg area. The dump had been largely removed, but water seeps and timbers of the shaft along with a large glacial boulder were still visible at the opening to the mine. The area of the mine has shale, siltstone, sandstone, conglomerate, limestone, underclay, coal and flint lithologies. Bedrock is from the Pennsylvanian Geologic Period. The photograph was taken during the summer field work of James Osborn Fuller and Myron T. Sturgeon in July 1941.
Columnar joints in the Black Hand Sandstone of the Cuyahoga Formation that forms Old Man's Cave at Hocking Hills State Park, Hocking County, Ohio. Old Man's Cave is a large rock shelter in the northwest valley wall of Old Man's Creek. It is formed in the weakly cemented crossbedded middle zone of the Black Hand Sandstone. The rock shelter cave is about 200 feet long, 50 feet high, and 75 feet deep. The resistant uppermost zone of the Black Hand sandstone forms the roof of the cave. Bedrock is from the Mississippian Geologic Period.
Rock House is the only true cavern at Hocking Hills State Park, Hocking County, Ohio. The outcrop of Black Hand Sandstone rises 150 feet from the valley floor overlooking Laurel Run. Halfway up the face of the cliff is a row of five to seven

Old Man's Cave is a large rock shelter in the northwest valley wall of Old Man's Creek. It is formed in the weakly cemented crossbedded middle zone of the Black Hand Sandstone. The rock shelter cave is about 200 feet long, 50 feet high, and 75 feet deep. The resistant uppermost zone of the Black Hand sandstone forms the roof of the cave. Bedrock is from the Mississippian Geologic Period. The photograph was taken by Michael C. Hansen in January 1978.
Outcrop of the Upper Mercer limestone of the Pottsville Group in Tuscarawas Township, Stark County, Ohio. This area has shale, siltstone, sandstone, conglomerate, limestone and coal lithologies. Bedrock is from the Pennsylvanian Geologic Period. Russell A. Brant is noted with the image information.This may be a photograph of work done by Richard M. DeLong for Measured Stratigraphic Section File Number 15129 in 1961.
An outcrop of the Pottsville Group-Sharon sandstone/conglomerate in Liberty Township, Jackson County, Ohio. Many scenic gorges, cliff exposures and outliers like this one known as
An outcrop of Black Hand Sandstone Member of the Cuyahoga Formation at the Blackhand Gorge State Nature Preserve, Licking County, Ohio. The Black Hand Sandstone is characterized by thick to massive beds of cross-bedded sandstone that form prominent cliffs. The Black Hand Sandstone bedrock unit was named for the large, dark, hand-shaped American Indian petroglyph carved into the cliff wall at the location of this nature preserve. The petroglyph was destroyed in 1828 during the construction of the towpath for the Ohio and Erie Canal. Bedrock in this area is from the Mississippian Geologic Period. This photograph was an entry in the 1983 Ohio Geology Slide Contest.
