Join Marshall University geology professor Dr. Michael Caudill at the Pickaway County Library in Circleville for a free talk on Uncovering the Ice Age in Pickaway County, exploring relict ice-wedge polygons and permafrost distribution along Pleistocene glacial margins in southern Ohio. Dr. Caudill, a former Ohio Geological Survey researcher, will explain how these Ice Age landforms reveal Pickaway County’s glacial history.
