The “dome” character of a laccolith, where the sedimentary rock layers are tilted upward on the mountain flanks, is evident at Mount Ellsworth in the Henry Mountains, Garfield County.
La Sal Mountains, Grand and San Juan Counties, Utah

The La Sal Mountains, near Moab in southeastern Utah, are laccoliths formed when upwelling magma intruded into and bulged the overlying sedimentary rock layers upward. The magma did not reach the surface, but subsequent erosion of the softer sedimentary rocks exposed the peak-forming igneous rocks that rise above the surrounding landscape.
From everyone at the Utah Geological Survey, we hope you have a Merry Christmas that rocks!

Morning sunlight illuminates water-sculpted walls of the Buckskin Gulch slot canyon. Cut deeply into Jurassic-age Navajo Sandstone, the Buckskin’s slot ranges from 5 to 25 feet wide and 100 to 500 feet high for 12 miles, making it the longest slot canyon in the world.

The Owachomo Bridge was created by stream erosion of the Permian-age Cedar Mesa Sandstone. Owachomo, a Hopi term meaning “rock mound,” is named for the large rock mass found on the northeastern abutment of the bridge.
