About this map

Ruby Mountains terrain dominates this 1990 provisional study, revealing a landscape defined by significant high-altitude mining activity. The area is marked by numerous Prospects and industrial sites, most notably the Little Bald Mountain Mine and various Mines and Mine Shafts scattered across the slopes. The settlement history is sparse but telling, with Joy (Site) indicating a former presence near the mountain flanks, while the locality of Martin appears in the southern portion of the quadrangle.

Water sources are critical landmarks in this arid high-country environment, documented through named locations such as Mill Spring, Bourne Tunnel Spring, and Tognini Spring. The steep topography is carved by distinct drainages including Bourne Canyon and Cherry Canyon, which descend from the heights of Big Bald Mountain. This map records the intersection of geological exploration and remote Nevada settlement at the end of the twentieth century.
