1986 Map of River Spring

About this map

Adobe Valley and the high desert basins of Mono County dominate this mid-1980s landscape at the boundary between Inyo National Forest and Toiyabe National Forest. The terrain is defined by its water sources, which were critical for the small settlement at Pizona and the surrounding livestock and transit routes. The map records a series of vital springs and catchments, including River Spring, Upper Pizona Spring, and Antelope Spring, which feed into local basins like River Spring Lakes and Antelope Lake.
