About this map

The Colorado River and Green River converge within the iconic sandstone labyrinths of Canyonlands National Park, defining a landscape where extreme erosion has carved features like The Needles and Upheaval Dome. This 1982 survey illustrates the transition from the high alpine environment of the La Sal Mountains down to the arid grabens of Lisbon Valley.

Industrial activity is centered in the eastern half of the map, particularly around the rich uranium and vanadium deposits of the Big Indian Valley. Named operations like the Mi Vida Mine, Homestake Mine, and Yellow Circle Mines reflect the era's intensive mineral extraction. The small settlement of La Sal remains the primary hub for this remote region, connected by U S 163 and Spanish Valley Road through the dramatic topography of Hatch Point and Behind The Rocks.
