Black Dragon Wash features some of the most interesting Indian rock art on the San Rafael Swell. The wash is named for the "Black Dragon," a pictograph that resembles a winged dragon. The Black Dragon Canyon is located near Green River. The canyon has pictographs left by ancient Fremont Indians, who inhabited Emery County from about 500 to 1300 AD. They left considerable evidence of their occupation, including campsites, stone granaries, and artwork painted (pictographs) or carved (petroglyphs) on canyon walls.
