The United States Atomic Energy Commission appears prominently in the margin of this 1948 topographic study, reflecting the intense mineral interest in this corner of Colorado. The landscape is defined by the massive Sewemup Mesa and Sinbad Valley, where geologic uplift and erosion created the distinctive Sinbad Ridge and Hog Trough. Uranium and vanadium mining history is evidenced by the Radium Cycle Mine and the Rajah Mine, while the Radium Trail snakes through the southern breaks of Red Canyon. In the lower elevations, the Paradox Sch and Paradox Ditch near West Paradox Creek show the thin footprint of settlement and irrigation in an otherwise desolate reach of the Dolores River canyon system. This survey captures the remote industrial activity within the Manti-La Sal National Forest during the post-war mining boom.
