Three people posed on Kelleys Island's Inscription Rock appear oblivious to the pictographs etched in the rock's surface. Research suggests the pictographs were carved by Erie Indians in the 1600s. Copies of the pictographs were made by the federal government around 1850. Although the rock is now protected by a roofed structure, the sun, wind, water, and human activity have destroyed nearly all traces of the pictographs.
