2020 Map of South of Big Pass

About this map

Great Salt Lake Desert dominates this 2020 landscape in western Tooele Co, Utah, providing a detailed look at one of the most desolate regions in the Great Basin. This high-resolution survey by the U.S. Geological Survey reveals the vast, flat expanses where salt crusts and seasonal water patterns define the geography. The most prominent feature on this sheet is the Newfoundland Evaporation Basin, a massive industrial or natural salt-harvesting feature that underscores the intersection of western mineral extraction and the unique hydrology of the salt flats. The map is primarily characterized by the Public Land Survey System (PLSS) grid, showing section lines across an area largely devoid of permanent human settlements or structures. It serves as a precise record of the topography and land boundaries within the desert floor during the early 21st century.
