Glacial Grooves at Kelleys Island, Ohio: Man quarried away many other grooves during the 20th century. Today, Glacial Grooves Geological Preserve at Kelleys Island features the remains of 18,000-year-old glacial grooves that are “protected” and measure 400 feet long, 35-feet wide, and 10-feet deep. Visitors can get up close for a good view and pictures of the grooves from an observation stairway/walkway. There are also marine-fossil remains in the limestone bedrock dating nearly 400 million-years-old.
