See American Indian symbols carved in rock on the south shore of Kelleys Island. Rediscovered partly buried in the shoreline in 1833, the rock is now entirely exposed and covered by a roof and viewing platform. Listed on the National Register of Historic Places, the Inscription Rock Petroglyphs are believed to have been created sometime between A.D. 1200 and 1600. Inscription Rock Petroglyphs are accessible daily in season, weather-permitting. Open year-round, dawn-dusk.
