2015 Map of Nellie Spring Mountain

About this map

Nellie Spring Mtn anchors this arid Great Basin landscape in Washoe County, where ephemeral water sources and distinct geological formations define the territory. The topography is dominated by the Massacre Range in the northwest and the deep cut of High Rock Canyon to the northeast. Navigation through this remote terrain follows the High Rock Canyon Rd, which traces the low ground near High Rock Cr. The map reveals a network of vital water points necessary for survival in the high desert, including Indian Spring, Lower Indian Spring, and Fern Spring. Man-made intervention is visible at the Argo Reservoir, while natural landmarks like Grassy Rock, Grassy Wash, and Grassy Canyon provide essential orientation in a region of shifting desert drainages.
