2010 Map of Grassy Mountains

About this map

The Grassy Mountains define the central axis of this Great Basin landscape, stretching across the quadrangle as a prominent topographical feature in Tooele County. This 2010 survey reflects a largely unpopulated desert environment, where the primary geographical markers are geological rather than residential. The southeastern portion of the map is punctuated by the isolated rise of Cobble Hill, which stands apart from the main mountain chain. Produced during the early 21st century by the U.S. Geological Survey, the map uses modern satellite imagery and national datasets to document the arid terrain and the sparse network of 4WD roads that navigate the basin floor. This data provides a detailed record of the natural contours and landforms before any significant infrastructure or commercial development altered the high-desert character of the region.
