Between three and four hundred years ago, Ohio pre-historic Indians, believed to be of the Erie tribe, pecked numerous inscriptions or pictographs on the top surface of this large native limestone rock. The figures, now nearly obliterated by the elements, measured and drawn in detail by Captain Seth Eastman, United States Army, in 1850. This relief of the Inscription Rock was made from the original Eastman drawing. Scale is approximately 1 to 15. The meanings of the pictographs are not known. There are at least eight human figures, all with headdresses and some smoking pipes; also animal and bird forms.
