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
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...
Ladd Natural Bridge is a natural bridge of resistant Permian Geologic Period Hockingport Sandstone near Cutler, Washington 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.� The image was taken by Timothy A. Snyder in 1988.
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 disconformity in the Ohio Shale and the Columbus Limestone at the East Liberty Stone Quarry in Logan County, Ohio. Bedrock is from the Devonian Geologic Period. The photograph was taken at Stop #4 of the Ohio Academy of Science field trip on April 26, 1969.
An outcrop with coal balls in the Ames limestone of the Conemaugh Group along United States Highway 22 west of Wintersville in Wayne Township, Jefferson County, Ohio. Coal balls are concretions of mineralized plant debris, occurring in coal seams or in adjacent rocks. This area has shale, siltstone, mudstone, sandstone, limestone and coal lithologies. Bedrock is from the Pennsylvanian Geologic Period. This image was taken by Michael C. Hansen in 1975.
The image shows a section of Ohio Division of Geological Survey's core DGS 3275 at the interval of 1807.1 to 1807.8 feet. Symbolism with notes on the slide indicates that this section of the core is associated with a right lateral syncline in the Wells Creek Formation. This core section comes from the transition zone of the Serpent Mound Impact Structure, which has dolomite, shale, limestone, sandstone, and siltstone lithologies. Because of the geologic forces that have acted on the site of the impact structure, bedrock in the area is a mixture of uplifted, down dropped, faulted, folded and eroded rock from the Ordovician, Silurian, Devonian and Mississippian Geologic Periods. In 1979, John L. Carroll Mineral Exploration...

Myron T. Sturgeon is pictured examining the toe of the slump at the Monticello Village Apartments landslip in Athens, Athens County, Ohio. The Monticello Village Apartments was a complex of fourteen to sixteen buildings when construction was finished in 1968. The level area on which the apartment buildings were constructed was fashioned from a cut on the hillside in the Clarksburg red bed. The mudstone removed in this cut was used as fill on the edge of the hill in order to expand the level area for apartment construction. On November 4, 1972, the slope failed, causing the destruction of a 150 meter section of Hastings Road in the location of Ohio State Route 32. On November 7, 1972, four buildings were evacuated...
