1986 Map of River Spring

About this map

Pizona serves as a remote focal point on this 1986 provisional survey, situated near the intersection of the Toiyabe National Forest and Inyo National Forest boundaries. The map highlights a complex network of hydrologic features along the California-Nevada state line, including the isolated waters of McNamara Lake and the extensive River Spring Lakes system. The geography is defined by the sharp transition between the Adobe Valley floor and the rising slopes of the Benton Range, where Antelope Mountain stands as a prominent landmark. This document details the essential water sources that supported activity in this arid high-desert corridor, from Antelope Spring to Upper Pizona Spring, while tracing the established Base Line and high-voltage Trans Line corridors that cross the desert floor.
