About this map

The Toiyabe National Forest blankets the high terrain where California and Nevada meet, a landscape defined by sharp elevation changes and critical water management. Centered on Topaz Lake, this modern survey illustrates the complex irrigation network supporting Antelope Valley, including the Topaz Canal, Wiley Ditch, and Alkali Ditch. These diversions from the West Walker River are essential to the agricultural history of the region.

Settlement patterns are concentrated at Topaz Ranch Estates and Holbrook Junction, while the surrounding peaks like Leviathan Peak and Wild Oat Mtn rise above the drainage basins of Slinkard Cr and Nevada Cr. The inclusion of the Topaz Lake Public Fishing Area and high-altitude crossings like Monitor Pass reflects the modern intersection of recreational access and historic ranching infrastructure.
