The Cedar Canyon Petroglyphs are dated back more than 200 years, with some of the petroglyphs unique to this location, including several panels that include depictions of plants and markings referred to as calendars. The surrounding landscape is known as the Red Desert, and is the traditional homeland of many Indigenous Nations who are known today as the Shoshone, Arapaho, Ute, Shoshone Bannock, Lakota, Cheyenne, and Crow tribes.
