Wind River Canyon Highway
Wind River Canyon is a magnificent channel carved more than 2,000 feet deep by the rushing waters of the Wind River. Engineers designed US 20 to be constructed by literally blasting it from the rock and tunneling through solid granite in three places. Unusual rock formations highlight the canyon walls, which are identified in terms of geological era and formation by strategically placed highway signs. One of the canyon's most prominent landmarks is Chimney Rock, about 10 miles south of Thermopolis. At the south end of the canyon is Boysen Dam, another engineering achievement.
