POTD May 19, 2015: Dead Horse Point State Park, San Juan County, Utah

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.

White traces of early snow dust prominent sandstone and limestone rock layers on Mount Timpanogos and contrast with lower-elevation yellow-tinted aspen trees. The sedimentary rocks are the Pennsylvanian-age Bear Canyon Member of the Oquirrh Formation that have been transported eastward over 30 miles on thrust faults.
