1973 Map of Floating Island SE

About this map

Hill Air Force Range dominates the northern portion of this orthophotomap, showing the stark intersection of military activity and the arid landscape of Tooele County during the early 1970s. The terrain is characterized almost entirely by an expansive Mud Flat, a featureless surface that highlights the isolation and specialized land use of the region. A survey Base Line crosses the lower third of the quadrangle, serving as a rare human-defined boundary in an area otherwise devoid of traditional settlements, roads, or structures. This 1973 field-checked study provides a precise visual record of the desert floor, where the natural playa surface was utilized for defense purposes within the wider Great Salt Lake Desert system.
