Lower Gray Canyon
Past sandy beaches, river rapids, and petroglyphs, this journey takes you into the 1,000 foot deep Lower Gray Canyon along the Green River.
The San Rafael Reef is cut through with deep, sinuous canyons adorned with ancient rock art panels. Within the Reef lies the deep Black Dragon Canyon, named for the flying dragon pictograph located on its wall.
Sego Canyon contains rock art from three different Native American cultures and ruins of a coal-mining ghost town. This site can be viewed as a short side trip from Interstate 70 east of Green River.
