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,...

Rock core sample showing the Pottsville Group-Sharon sandstone/conglomerate. The sample is from Core Record File No. 2541 in Raccoon Township, Gallia County, Ohio. This area has shale, siltstone, sandstone, conglomerate, limestone and coal lithologies. Bedrock is from the Pennsylvanian Geologic Period. The photograph was taken by Michael C. Hansen in 1982.
The exposed core sample at the site of an American Aggregate Corporation quarry lease near the town of Lytle, Warren County, Ohio, where the Ohio Geological Survey's Longyear Hydro-44 drill core rig worked the Warren County Deep Core Hole project. The Warren County Deep Core Hole project was the second continuously cored hole planned to be drilled into the Precambrian basement rock in Ohio. The Ohio Geological Survey expected to reach the Precambrian rock at a depth of about 3,400 feet. At that depth, the drill rig encountered a previously unknown massive sandstone formation underlying the Mount Simon Sandstone of Upper Cambrian rock. The core hole went 1,910 feet into this sandstone. This core DGS # 2627 went to...
