1973 Map of Finger Ridge

About this map

Hill Air Force Range dominates this landscape in the early 1970s, serving as a restricted military testing and training ground within the Great Salt Lake Desert. This orthophotomap provides a photographic record of the stark terrain, where the arid expanse of Mud Flat meets the distinct elevation of Finger Ridge to the east. The map captures the boundary between Box Elder Co and Tooele Co, illustrating how administrative lines were drawn across this desolate environment. The visible surface patterns in the orthophotomosaic reveal the complex network of salt crusts and seasonal water drainage that define the basin floor, providing a unique visual perspective of a region largely inaccessible to the public due to its Restricted status.
