Outcrop showing contact between the uranium-rich Huron Member of the Ohio Shale with overlying till of Wisconsinan age along the Lake Erie shoreline at Showse Park, Vermilion, Lorain County, Ohio. Pleistocene glaciers eroded large amounts of Ohio Shale and incorporated these fragments in tills. Note vertical cracks in the till. These fissures provide avenues for upward migration of radon. Unit lithology in this area is shale, siltstone, and sandstone. Bedrock is from the Devonian Geologic Period. Ohio Geological Survey employee Merrianne Hackthorn is pictured next to the outcrop for scale. The photograph was taken by David B. Buchanan probably in April 1983.

A scenic view of Rockbridge with waterfall 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...
