Geology and uranium deposits of Elk Ridge and vicinity, San Juan County, Utah

Abstract

l'he Elk Ridge area covers approximately 1,000 square miles in Sau Juan County, Utah. It lies between the Abajo Mountains and the White Canyon area and includes Elk Ridge, The Needles, and Beef Basin. The top of Elk Ridge ranges in altitude from 7,000 to 9,000 feet above sea level, and forms a broad convex mesa bounded by steep-walled canyons. On the basis of physiography, two general d~visions can be made of the area: (1) Elk Ridge and (2) surrounding lower mesas. Both subareas are dissected by deep, steep-walled canyons.
