Rediscovery
Inscription Rock was discovered partially buried in the sand of the lake shore in 1833
and by 1915, it was appearing on postcards for tourists in the area and is still a well-visited site to this day.
In 1851 Col. Eastman of the United States Army was commissioned to analyze and create detailed drawings of the rock and petroglyphs. He then submitted copies to Shingvauk, a Native American with a knowledge of pictography, for further interpretation.
There are over 100 images on the rock and the carvings were noted to be similar to ones used by the

Due to the soft nature of the limestone rock in the area, the carvings are generally believed to be less than 1,000 years old but the Inscription Rock remains one of the most significant and accessible examples of native petroglyphs in the area. Due to its proximity to the Lake Erie shoreline, it is under constant threat of further erosion by wind and wave activity.
