About this map

Sierra Estrella peaks dominate the eastern horizon of this 1970s desert landscape, marking a sharp boundary for the Gila River Indian Reservation. The terrain below is defined by the broad Rainbow Valley, a drainage basin carved by the winding Waterman Wash and its western tributary, West Prong. This survey illustrates the early stages of infrastructure development in the arid Maricopa County interior, noting the placement of a major Pipeline and early thoroughfares like Chandler Hts Rd and Riggs Rd.

Water management is central to the land's utility, evidenced by a scattering of industrial and agricultural sites. Numerous wells are noted throughout the valley floor, alongside specialized livestock or irrigation features such as Big Mac Tank and Big Bertha Tank. Evidence of mineral exploration appears near the mountain slopes, including a Prospect and a Dry Well, reflecting the era's ongoing assessment of the region's natural resources.
