Enhance your visit to Kelleys Island and join Pat Hayes, Kelleys Island Audubon President, for a walk around the historic Glacial Grooves.
The Glacial Groovesare the most popular natural destination on Kelleys Island. Our grooves are thelargest and best accessible example of this geological phenomenon anywhere in the world!They arelocated at the intersection of Division Street and Titus Road, only a mile and a half north of downtown.
Theglacial grooves are 400 feet long, 35 feet wide, and up to 15 feet deep. They were created by the slow movement ofthe massive glacier that created the Great Lakes and Lake Erie Islands. When glaciers move across the earth, they pick up rocks, soil, and other debris, and dragthem along.As the ice crept over the soft limestone bedrock of Kelleys Island, these harder bits of rock gouged the grooves that we see today.Originally, the grooves were filled with soil, debris, and quarry waste.In 1972, excavation to uncover the full extent of the grooves began, and theyhave been a popular tourist attraction ever since.The grooves are also important to historians, scientists and students. They give us valuable information about the direction and movement of the glaciers that shaped our entire landscape.If you only have time to visit one Kelleys Island destination, the Glacial Grooves are not to be missed!
