Sunset on Gooseberry Mesa shines golden light on cliffs of Triassic-age Shinarump Conglomerate and the underlying slope-forming Moenkopi Formation. White cliffs and peaks in the distance are thrones and temples of Zion National Park, formed of Jurassic-age Navajo Sandstone.

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.
Wishing our Tuesday was spent out there! The weather just gets nicer and nicer by the day. What Utah places do you want to explore this year?

Fluted crimson walls of Jurassic-age Entrada Sandstone rim Cathedral Valley in the remote northern part of Capitol Reef National Park. The near-vertical Entrada walls owe their existence to the overlying white Curtis Formation that serves as a protective cap rock.

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).
The mornings are becoming a little crisper, and night comes a little quicker. It won’t belong before we see this scene!

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.
While this photo is a throwback to colder seasons, we cannot deny the stunning #UtahGeology present. This crisp, cold picture is worth a thousand hand warmers—that’s how the saying goes, right?

The Colorado River loops around the Gooseneck between Dead Horse Point State Park and distant cliffs of the Island in the Sky District of Canyonlands National Park. The river has carved and exposed nearly flat-lying Jurassic to Pennsylvanian-age sedimentary strata of the Colorado Plateau.
