Glacial grooves on Kelleys Island
Description: Original description reads: "Kellys Island." The Glacial Grooves on the north side of Kelleys Island are the largest easily-accessible such grooves in the world. They were scoured into solid limestone bedrock about 18,000 years ago by the great ice sheet which covered part of North America. A trough 400-feet long, 35-feet wide, and up to 10-feet deep remains today. The Glacial Grooves are a National Natural Landmark, part of the Ohio History Connection statewide network of historic sites. View on Ohio Memory.
