The setting sun illuminates the Jurassic-age Navajo Sandstone cliffs of Cougar Mountain (right) and South Guardian Angel (left) as viewed from Kolob Reservoir Road. Here, the road travels on top of the 220,000- to 310,000-year-old Grapevine Wash lava flow (dark rocks in middle ground).

Yellow sulfur crystals and various colors of bacteria and algae give these hissing steam vents and bubbling pools an otherworldly look. This landscape is a recent and evolving phenomenon resulting from changing groundwater levels associated with nearby geothermal power generation.

Snow highlights cross-bedding on the sides of buttes and mesas along the Clear Creek drainage on the east side of Zion National Park. Cross-beds in the nearly 2,000-foot-thick Jurassic-age Navajo Sandstone formed in ancient sand dunes and reflect changing wind directions as the sand was being deposited.

Alpenglow illuminates the glacially sculpted Stansbury Mountains as seen from the shores of Great Salt Lake. Deseret Peak (11,031 feet), the leftmost high summit, is the range’s highest peak and is underlain by Cambrian-age Prospect Mountain Quartzite.
