Towering 1,488 feet above the canyon floor, Angels Landing is a joint-controlled resistant fin of Jurassic-age Navajo Sandstone, carved out by the incised North Fork Virgin River. A popular, but steep and exposed, hiking trail guides park visitors along the sheer fin to inspiring views of Zion Canyon.

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).

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.

One of numerous slot canyons carved into Jurassic-age Navajo Sandstone in Zion National Park, Bear Trap Canyon is particularly dark and narrow. With little sunlight penetrating to the canyon floor, snow and ice often linger well into spring. Zion National Park, Washington County, Utah Photographer: Tyler Knudsen; © 2014
