About this map

Hill Air Force Range occupies the northern expanse of this 1973 orthophotomap, where the desert floor transitions into the restrictive boundaries of military testing grounds. The landscape is dominated by a sweeping Mud Flat, a featureless and level terrain that highlights the stark environmental conditions of the Tooele County desert. This orthophoto format, created from 1972 aerial photography, provides a rare visual record of the ground surface texture before any modern modifications. The southern portion of the sheet is bisected by the Base Line, a critical surveying boundary that marks the division between Township 1 North and Township 1 South. This intersection of military land use and foundational public land survey system markers illustrates how the remote Utah desert was organized and managed during the early 1970s.
