Standing at the edge of Kelleys Island’s Glacial Grooves, you can’t help but feel dwarfed by the sheer scale of nature’s handiwork. These massive limestone channels, carved by mile-thick glaciers thousands of years ago, are the largest accessible glacial grooves on Earth—right here in Ohio! It’s wild to think that ice, not humans, sculpted this prehistoric art. The grooves are a time capsule, revealing both ancient sea fossils and the raw power of the Ice Age. If you’ve ever doubted Ohio’s natural wonders, this spot will change your mind. Who else has visited and felt that sense of awe? #Travel #OhioAdventures #KelleysIsland
