The Grand Hogback dominates the southern landscape of this 1952 study, a prominent geological ridge that separates the high plateau country from the valley floor. During this era, the region supported a specialized mountain economy centered on natural resource extraction and high-altitude grazing. Evidence of local industry is visible through multiple Coal Mines and a specifically noted Coal Mine (Active) located near the southeastern corner. This area also includes a significant portion of the Naval Oil Shale Reserve, reflecting the strategic energy interests of the federal government in Garfield County during the mid-20th century.
