1991 Map of Big Pass

About this map

The Newfoundland Mountains rise sharply out of the vast, level expanse of the Great Salt Lake Desert in this 1991 survey. The landscape is defined by the stark contrast between the high relief of the range and the surrounding Newfoundland Evaporation Basin, where a dashed blue line at 4217 feet indicates the high-water elevation of the seasonal salt flats. This area, located near the border of Box Elder and Tooele counties, is heavily influenced by government operations, with a significant portion of the terrain falling within the Utah Test and Training Range North. A remote Landing Strip sits at the base of the mountains, while Big Pass provides a natural corridor through the northern heights. The map captures the isolation of this desert environment, marked primarily by mineral flats and the Military Reservation Boundary that limits public access.
