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.

Late-winter ice still clings to the Colorado River near Big Bend, north of Moab. Boulders of Jurassic-age Wingate Sandstone and Triassic-age Chinle Formation line the banks of the river, eroded from the cliffs and ledges cut by the river as it has incised its channel over millions of years.

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.

At Long Canyon, stream erosion has carved a deep gorge into the east limb of the Cane Creek anticline. The canyon exposes dark-brown Triassic-age shale and sandstone of the Moenkopi and Chinle Formations capped by vertical cliffs of Triassic and Jurassic-age sandstone of the Wingate and Kayenta Formations.
Another weekend gone by, and a photo to greet you on your Monday morning. Who went somewhere fun this weekend?

The Klondike Bluffs 7.5′ quadrangle covers a large part of Arches National Park and encompasses colorful bedrock strata ranging in age from Pennsylvania Paradox Formation to Cretaceous Mancos Shale. Salt diapirs are common throughout the area, and the Salt-Cache Valley Salt Structure is the most prominent structure, with several additional salt structures present, including the Salt Wash and Courthouse synclines and the Elephant Butte folds. Scenic resources in the area showcase joints, fins, grabens above salt wells, and the highest concentration of arches in the world.
This CD contains geographic information system (GIS) files in ESRI file geodatabase and shapefile formats. A geologic map at 1:24,000 scale and a 31-page booklet are also included in PDF format. The latest version of Adobe Reader is required to view the PDF files.

Salt diapirs are common throughout the area, and the Salt-Cache Valley Salt Structure is the most prominent structure, with several additional salt structures present, including the Salt Wash and Courthouse synclines and the Elephant Butte folds. A one-mile-wide zone of faults is located in the Windows Section northeast of the Moab fault. Scenic resources in the area showcase joints, fins, grabens above salt walls, and the highest concentration of arches in the world.

Mount Tukuhnikivatz, a prominent peak in the La Sal Mountains, is an erosional remnant of magma that rose from depth (but never reached the surface) about 28 million years ago, forcing through and pushing up the area’s layered sedimentary rocks.
