About this map

Portland Mine and several scattered prospects define the industrial character of this desert landscape in the late 1960s. The terrain transitions sharply from the rugged western heights of the Black Mountains down into the expansive Detrital Valley to the east. Water management is central to survival and livestock operations here, evidenced by a network of catchments and sources including Cottonwood Reservoir, Middle Tank, and Squaw Pocket Well. Drainage patterns are carved by Lost Cabin Wash and Portland Wash, which flow toward the valley floor. The map records a sparse but functional infrastructure of unimproved roads and corrals, such as Corral Junction Tank, indicating the area's use for both mining exploration and open-range ranching during this period.
