Book Description

On Polar Mesa in Grand County, Utah, a total of 37,904 feet was drilled by the Atomic Energy Commission in 1950 under contract AT(30-1)-761. The mesa was again drilled during the period June 1952 to February 1953, under contract AT(30-1)-1265, which totaled 49,838 feet. This report deals primarily with the most recent project. The principal uranium-vanadium-bearing unit of the Salt Wash sandstone is approximately 270 feet above the Entrada-Summerville contact. It is a massive yellow-brown sandstone ranging in thickness from 10 to 70 feet. A method of correlation involving the projection, parallel to the regional dip, of a constant thickness of sediments was an aid in exploration drilling.
