2021 Map of Pahroc Summit Pass

About this map

The high desert landscape of Lincoln County unfolds across this 2021 survey, centered on the broad expanse of Pahroc Valley and its surrounding mountain ranges. The northern portion of the Pahroc Range and the South Pahroc Range dominate the topography, providing a dramatic backdrop to the arid plains. Water resources in this environment are sparse and highly engineered, with livestock or irrigation-focused features like White-Sage Reservoir, Knoll Pond Reservoir, and Mackay Reservoir positioned to collect seasonal runoff. Natural water sources are limited to small, discrete points such as Six Mile Spring and East Boulder Spring. The map documents a mostly unpopulated terrain where the primary human footprint is found in the scattered reservoirs and the corridor of Route 93, which cuts through the northern sections of Delamar Valley.
