1970 Map of Yucca NE

About this map

The Automotive Proving Ground occupies the southwestern portion of this desert landscape, indicating the mid-century industrial utility of the Arizona backcountry. Broad alluvial washes dominate the Sacramento Valley, where seasonal drainage systems like Walnut Creek, Rock Creek, and Willow Creek carve through the arid terrain. Human activity is marked by a network of Jeep Trails and a prominent north-south Pipeline that bisects the valley floor. The placement of several Water Tanks suggests the critical importance of managed water resources for both the testing facility and local infrastructure during the early 1970s. This survey, grounded in 1969 aerial photography, documents a period when the valley served as a specialized zone for vehicular endurance and utility development.
