Inscription Rock Petroglyphs at Kelleys Island, Ohio: Archeologists believe that these prehistoric Indian rock inscriptions date between 1200 and 1600. Much of the 32 X 21 foot rock has been eroded through time by the lake but a roof has since been built to preserve what’s left and a viewing platform for created for visitors to appreciate the remains. The drawings are of people and animals carved into limestone. It was discovered in 1833.
