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.

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 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.
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.
A clay dike in Meigs Creek (No. 9) coal. Ohio State Geologist Horace R. Collins visited the area being mined by the Big Muskie dragline with Russian geologist Petr Petrovich Timofeev (Timofeyev) and geologist James Morton Schopf. The Big Muskie was a coal mining Bucyrus-Erie dragline owned and operated by the Central Ohio Coal Company. Big Muskie removed overburden to access Meigs Creek (No. 9) coal in the Muskingum, Morgan, Noble, and Guernsey counties area. The Big Muskie was officially dedicated during a ceremony on May 22, 1969. This picture was taken on May 24, 1969, during the opening week of public tours.
The 300-ton coal tipple at the Muskingum Electric Railroad's loading loop area south of Cumberland, Morgan County, Ohio. The Muskingum Electric Railroad was the first truly automated railroad in the United States. It was operated by the Central Ohio Coal Company, a subsidiary of the Ohio Power Company, to transport Meigs Creek (No. 9) coal that was developed from the strip mining operation of the Big Muskie. The coal from the mines was trucked to the Muskingum Electric Railroad's loading area south of Cumberland, dumped at trestle, then cleaned and put on surge pile for loading at tipple where the railroad's remote controlled diesel was kept. The two Muskingum Electric locomotives, No. 100 and No. 200, were built...

Big Muskie dragline removing overburden at a coal strip mine operation in Muskingum County, Ohio. The image was taken by Michael C. Hansen in March 1983. Big Muskie was dedicated on May 22, 1969, at a ceremony held in northern Morgan County near Renrock, Ohio. At the time, it was described as the world's largest mobile land machine and the biggest walking dragline ever built. It could remove 325 tons of earth and rock a minute. Big Muskie was operated by the Ohio Power Company and its parent firm American Electric Power Company. It operated in Ohio from 1969 to 1991.
An abandoned mine on Wills Creek, in Conshocton County, Ohio. Spoil tip is shown in the foreground of the image. The photograph was taken by David B. Buchanan probably in the 1980s for the United States Office of Surface Mining. David worked for the Office of Surface Mining from 1985 through 1995.
The Redstone-Pomeroy (No. 8a) coal bed at the base of a strip mine near Cadiz, Harrison County, Ohio. The mine was visited as part of the coal sampling program. The image was made in September 1980. The location approximate to the township.
A Keller Mining Company strip mine for the Newland-Brookville (No. 4) coal in Smith Township, Mahoning County, Ohio. The photograph was taken at the location of Measured Stratigraphic Section File Number 15124, measured by Richard M. DeLong and Russell A. Brant on March 31, 1961.
