Bryce Canyon National Park, Garfield County, Utah

Water plunges over a dolomite ledge within the otherwise easily erodible limestone of the Eocene-age Claron Formation in Water Canyon. A canal (the “Tropic Ditch”) diverts water from the East Fork of the Sevier River seven miles across the Paunsaugunt Plateau divide to the head of Water Canyon, creating a steady flow during the summer and fall that is vital to the nearby towns of Tropic and Cannonville.

Ruins of the Harrisburg town site, established by Mormon pioneers in 1861, consist of blocks of Early Jurassic-age Springdale Sandstone, which a mile to the north is the main ore-bearing horizon of the Silver Reef mining district. The mining district is famous among geologists for its uncommon occurrence of silver ore in sandstone. In the distance, the Pine Valley Mountains tower 7,000 feet above the surrounding red-rock country.
