Inscription Rock (Kelleys Island, Ohio)

Inscription Rock is a large slab of limestone measuring approximately 32 by 21 feet located on the south shore of Kelleys Island in Lake Erie in Erie County, Ohio. It is situated near the intersections of E Lakeshore Drive and Addison Rd under a large shelter structure with a viewing platform and is open to the public. The rock was listed on the National Register of Historic Places in 1973 and was also located near a series of crescent shaped mounds thought to be created by Pre-Columbian peoples. More mounds were documented to be on the island and another rock with inscriptions was located on the north shore of the island. Unlike Inscription Rock, this boulder was granite - likely a glacial erratic - and engraved with two upside-down figures. However now only Inscription Rock remains since island quarry workers dynamited the petroglyph rock on the north shore.
