About this map

Chocolate Mtn and Sugarloaf Mtn dominate the central and eastern portions of this high-desert landscape along the California-Nevada border. This survey captures a remote region where the White- Inyo Range meets broad basins. The transition from the steep elevation of Gilbert Pass down into Owens Valley is sharply defined by topographic contours, reflecting the basin-and-range geology characteristic of the area.

Surface water is sparse, marked primarily by Tule Spring and seasonal drainages like Wyman Cr and Cottonwood Cr. Human activity is centered on a light network of ranching and access roads, including Oasis Ranch Rd and Eureka Valley RD. The map clearly delineates the administrative boundary between Mono County and Inyo County, providing a detailed look at how these historical geopolitical lines bisect the varied terrain of Fish Lake Valley and Deep Springs Valley.
