Legend Rock Petroglyph Site is located in Hot Springs County, Wyoming, 20 miles northwest of Hot Springs State Park (which is located in Thermopolis, Wyoming). Legend Rock is a petroglyph site which features hundreds of individual petroglyphs spread across the face of the rock. Although a handful of the rock's etchings have variously been eroded and defaced, a wide majority have been preserved for public viewing. The nearly 300 individual petroglyphs feature some of the oldest and best examples of Dinwoody rock art in the world. The origins of the petroglyphs are still subject to debate. The site was listed on the National Register of Historic Places on July 5, 1973. and it is preserved by the state of Wyoming as a state historic site.
