Mark J. Camp, Associate Professor of Geology at the University of Toledo and author of the recently published Roadside Geology of Ohio, will lead us on virtual field trips from Marion.
We will begin heading southwest to the oldest bedrock in the state, examining exposures in roadcuts, spillways, and quarries between Dayton and Cincinnati.
A trip west will lead to exposures of slightly younger rock of Silurian age and the isolated patch of Devonian rock around Bellefontaine.
Heading south brings us to the edge of glaciated Ohio at Chillicothe and into the dissected Mississippian sandstone terrain of the Hocking Hills near Logan.
Traveling east will eventually lead to the youngest bedrock of the state — the Pennsylvanian and Permian.
A journey north will uncover landforms, sediments, and fossils associated with the great ice sheets that periodically covered a good portion of the state over the last two million years.
