1963 Map of Rhyolite Ridge

About this map

Silver Peak Range dominates this mid-century topographic survey of Esmeralda County, revealing a landscape defined by mining prospects and desert hydrology. The rugged terrain is punctuated by historic routes and high points like Emigrant Peak and Emigrant Pass, while the broad Big Smoky Valley and Lake Valley occupy the lowlands. Localized water sources, critical for survival and industry in this arid environment, are mapped at Minnesota Spring, Valcalda Spring, and Gap Spring. The presence of an Old Railroad Grade in the northeast and scattered Landing Strips reflects the evolving transport infrastructure of the Great Basin. Dozens of unspecified prospects and prospect markers across the ridges of Rhyolite Ridge and Red Mtn illustrate the intensity of mineral exploration that shaped this region's early history.
