1954 Map of Granite Peak SE

About this map

Dugway Proving Ground dominates this mid-century topographic study, illustrating the intersection of military operations and the unforgiving terrain of the Great Salt Lake Desert. The eastern portion of the sheet is defined by the steep, rocky slopes of Sapphire Mountain, which rises abruptly from the surrounding basin. This area represents a stark landscape of isolation where the Mud Flat spans the western reaches, showing the characteristic level, featureless topography of Utah’s salt flats. Originally compiled from 1953 aerial photography with subsequent revisions in 1984, the map records the boundaries of the military reservation as it existed during the height of the Cold War, reflecting the region's importance for defense testing within the vast Tooele County desert.
