An outcrop with the Olmstead Bed of the Cleveland Shale Member of the Ohio Shale along the Vermilion River in the Vermilion River Reservation Park, Lorain County, Ohio. Unit lithology in this area is shale, siltstone and very fine-grained sandstone. Bedrock is from the Devonian Geologic Period. The photograph was probably taken by Dr. Paul Potter in the 1980s.
An outcrop showing contact of the Bedford Shale with the Berea Sandstone on the west side of Interstate 77 south of mile marker 155 at Independence, Cuyahoga County, Ohio. Bedrock is from the Devonian Geologic Period. The photograph was taken by Michael C. Hansen in 1981.
An outcrop along the Baltimore and Ohio Railroad Company tracks in Harrison Township, Scioto County, Ohio.The outcrop shows the bedrock contact between the Mississippian and Pennsylvanian Geologic Periods. This area has shale, siltstone, sandstone and conglomerate lithologies. The photograph was taken in 1968.

Outcrop with Brassfield Formation in Bratton Township, Adams County, Ohio, on State Route 73. Unit lithology in this area is limestone with interbedded shale and dolomite. Bedrock shows the contact between the Ordovician and Silurian Geologic Periods. Michael C. Hansen took this photograph in 1978.
The image shows a close-up of a section of Ohio Division of Geological Survey's core DGS 3275 at the interval of 1693.3 to 1693.8 feet. This section shows a calcite-filled fault in the Black River Group. 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 of New York City drilled two core holes in the Serpent Mound...
Damage to Hastings Road below 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 after additional rapid movement...
