Description

View of the Glacial Grooves on the north side of Kelleys Island, Ohio, ca. 1930-1960. These are the largest such grooves in the world that can be easily seen. They were created in limestone bedrock about 18,000 years ago during the Ice Age. A trough 400 feet long, 35 feet wide, and up to 10 feet deep remains today. The ice, probably hundreds of feet thick, moved from the north into what is now the Lake Erie basin. The grooves contain marine fossils that are 350 to 400 million years old. Other grooves on the island were destroyed by quarrying.
