1973 Map of Granite Peak NW

About this map

The vast salt-crusted terrain of the Mud Flat dominates this 1973 orthophotomap of Tooele County. Captured through aerial photography, the landscape reveals the stark, geometric interface between natural alkali basins and the strictly controlled boundaries of the Dugway Proving Ground. This specialized topographic study provides an uncompromising look at the environmental isolation of the Great Salt Lake Desert during the mid-1970s. The map illustrates how human administrative lines, such as the townships of T 7 S and T 8 S, cut across an otherwise featureless expanse, where fine-grained textures in the orthophoto mosaic expose the subtle variations of the arid basin floor.
