Desolation Canyon in Utah
This photo, taken on Dec. 31, 2000, shows Utah's Green River flowing south across the Tavaputs Plateau before entering Desolation Canyon, according to the USGS. Desolation Canyon is a popular river-rafting spot in Utah. It is noted for its rock art sites and Native American ruins. However, it was not a popular site with settlers in the 19th century, as many found the terrain too wild to cultivate.
