1991 Map of West of Big Pass

About this map

Newfoundland Evaporation Basin dominates this desolate landscape in the Great Salt Lake Desert, where the shifting expanse of Mud defines the terrain. The map captures a specialized environment of salt flats and evaporation areas at the intersection of the Box Elder Co Tooele Co line. Significant portions of the southern quadrangle are restricted, marked by the Military Reservation Boundary that cordons off the Utah Test and Training Range North. This 1991 survey, which utilized aerial photography from 1973 and 1987, reveals a landscape primarily shaped by modern military utility and hydraulic management rather than traditional settlement. The presence of the military range underscores the region's historical role as a remote testing ground, away from the populated corridors of northern Utah.
