1982 Map of La Sal

About this map

Canyonlands National Park dominates the western landscape of this 1982 survey, where the confluence of the Green River and Colorado River carves through deep sandstone formations. The map captures a dramatic transition from the high-altitude La Sal Mountains and Manti-La Sal National Forest in the east down to the intricate labyrinths of The Needles and The Grabens. This period shows the industrial footprint of the region's uranium and potash history, particularly evident in the Lisbon Valley and Big Indian Valley where the Lisbon Mine and Big Indian Mine are situated. Settlement is sparse, clustered primarily around La Sal and La Sal Junction along US Highway 191, reflecting a landscape defined more by its massive geological features like White Rim and Hatch Point than by urban development.
