This quadrangle covers 1780 square miles and is located predominately in Arapahoe and Adams County. It also extends into Douglas and Elbert Counties. Within the quadrangle the major structural feature is the Denver Basin. The coal and lignite resources, which occur in the Laramie Formation and Denver Formation, respectively, are greater than previously thought. Factors affecting potential mining are discussed.
