Bass Islands Dolomite outcrop with stalactites in a cave on South Bass Island, Put-In-Bay Township, Ottawa County, Ohio. This area has dolomite, anhydrite, gypsum, salt and shale lithologies. Bedrock is from the Silurian Geologic Period. The slide image was created in 1952 by Philip M. Smith for the Ohio Cave Survey Project. The Ohio Cave Survey Project was formalized in 1952. The Central Ohio Grotto of the National Speleological Society in cooperation with the Ohio Geological Survey established a comprehensive survey of Ohio caves and caverns. The location is approximate to the center of the island.
Fault plane breccia in the Peebles Dolomite at the Plum Run Stone quarry located two miles east of Peebles in Adams County, Ohio. This area has dolomite, shale, limestone and sandstone lithologies. Bedrock is from the Silurian Geologic Period. The image was made by Michael C. Hansen in 1978.
View of a salt wall inside the International Salt Company's mine operation site at Cleveland, Cuyahoga County, Ohio. The darker veins are anhydrite. Ohio's rock-salt deposits are confined to the Salina Group of the Silurian Geologic Period. The F unit of the Salina Group is the principal salt-bearing unit in Ohio and is further subdivided into four units. The F2 unit is mined by the International Salt Company at the Cleveland Mine. The underground mine is operated on a room and pillar system that leaves central pillars of salt to hold up the structure. The image was made by Michael C. Hansen in 1975.
A fault in rock face at the International Salt Company's mine operation site at Cleveland, Cuyahoga County, Ohio.

The Celotex Corporation gypsum mine facilities at Gypsum in Portage Township, Ottawa County, Ohio. After the gypsum-bearing rock was mined, an in-pit crusher reduced the size of the rocks to 2-3 inches. A conveyor then transported the rock to the plant, where the gypsum was separated from dolomite and shale by heavy-media separation. Commercial gypsum production in Ohio is from the F unit of the Salina Group where the gypsum occurs as nodules, lenses, and massive beds. Bedrock is from the Silurian Geologic Period.
A sinkhole in a field north of the area of Bellevue, Sandusky County, Ohio. The image was taken by Michael P. Angle during his field work for surficial mapping in April 1988.

Cliffs near Lynx, Ohio, in Adams County. Unit lithology in this area is shale and dolomite. Bedrock is from the Silurian Geologic Period. This image was an entry in the 1982 Ohio Geology Slide Contest.
The Plum Run Stone quarry near Peebles, Adams County, Ohio. This image was taken near a fault with graben foramtion in the quarry. The Plum Run quarry is about 6 miles southeast of the central uplift of the Serpent Mound disturbance. According to Subsurface Geology of the Serpent Mound Disturbance, Adams, Highland, and Pike Counties, Ohio (Report of Investigations No. 146, page 9), a series of north-northwest-oriented grabens, bounded by normal faults and folds, has been observed at the Plum Run quarry. This area has dolomite, shale, limestone and sandstone lithologies. Bedrock is from the Silurian Geologic Period. The photograph was taken by Gerald H. Newsom during the American Association of Petroleum Geologists...
This photograph shows near vertical strata on the Central Peak of the Serpent Mound Impact Structure on the William V. Martin farm north of Peebles in Adams County, Ohio. This area has dolomite, shale, limestone, sandstone, and siltstone lithologies. Because of the geologic forces that have acted on the site of the impact crater, 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. The photograph was taken by Gerald H. Newsom during the American Association of Petroleum Geologists Eastern Section Meeting Field Trip to the Plum Run Quarry and the Serpent Mound Disturbance on October 10, 1998. The Serpent...
A Landsat Thematic Mapper satellite false-color image with lineaments showing the central peak of the Serpent Mound Impact Structure. The image was taken in September 1994 and processing was done by the Ohio Department of Natural Resources, Division of Real Estate Management. The image was used for Subsurface Geology of the Serpent Mound Disturbance, Adams, Highland, and Pike Counties, Ohio by Mark T. Baranoski, Gregory A. Schumacher, Doyle R. Watts, Richard W. Carlton, and Belgasem M. El-Saiti (Report of Investigations No. 146) published by the Ohio Division of Geological Survey in 2003. The Serpent Mound Impact Structure is an approximately 9-mile-diameter area of highly disturbed and structurally deformed bedrock...
The image shows a close-up of sections in Box 22 of Ohio Division of Geological Survey's core DGS 3274 at the interval of 213.5 to 214.5 feet and 215.5 to 216.5 feet. This core section comes from the central uplift 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 Impact Structure in Bratton Township,...
