1983 Map of Round Mountain SW

About this map

Hill Air Force Range dominates this 1983 orthophotomap, showing the stark, functional landscape of military testing grounds in the Great Salt Lake Desert. The terrain is characterized by the expansive Mud Flat, a vast level basin that stretches across the border of Box Elder Co and Tooele Co. This specific survey, based on 1973 aerial photography, provides a rare visual of the land's surface texture, where the barren flats meet the rising slopes of the Grassy Mountains in the southeastern corner. A solitary Observation Tower stands as a rare vertical landmark in a landscape otherwise defined by subtle elevation contours and the rhythmic patterns of desert drainage. This map is particularly valuable for researchers of Cold War-era military infrastructure and the physical geography of the Bonneville Salt Flats region.
