The view through North Window arch in The Windows Section of Arches National Park reveals snow-covered sandstone spires and fins of the Jurassic-age Entrada Sandstone. The spires and fins result from weathering and erosion along parallel fractures, or joints, in the rock.
For those of our friends that can’t get out into the outdoor wonder-world this weekend, here are some stunning photos to keep you company.

Turret Arch viewed through North Window arch in The Windows Section of Arches National Park. The arches formed as the result of erosion through weak parts of sandstone fins composed of Jurassic-age Dewey Bridge Member of the Carmel Formation and Slick Rock Member of the Entrada Sandstone.

Dissolution of subsurface salt caused the collapse of the Salt Valley anticline, forming vertical fractures in the Jurassic-age Entrada Sandstone. Weathering along the fractures has produced the spectacular fins, towers, and arches in the Devils Garden section of Arches National Park.

A geologist examines a sequence of Early Cretaceous-aged paleosols (ancient soils) in the Yellow Cat Member of the Cedar Mountain Formation. Many dinosaur fossils are found in these rocks, and the study of paleosols can provide valuable
information about the environments in which these dinosaurs lived.

One of the most photographed geologic formations in Utah if not the world, the Entrada Sandstone is the featured rock unit of Arches National Park, Goblin Valley State Park, Kodachrome Basin State Park, and parts of Glen Canyon National Recreation Area. Variations in the Entrada’s appearance across the state are due to differences in internal structure and composition as well as external stresses.
