2012 Map of Topaz Lake

About this map

Topaz Lake straddles the high-altitude border region between Nevada and California, serving as a focal point for this 2012 survey. The landscape is defined by the sharp transition from the aquatic basin to the surrounding peaks, including Wild Oat Mountain to the east and the high ridges of Leviathan Peak and Monitor Pass to the southwest. Settlement patterns are concentrated at Holbrook Junction and the residential layout of Topaz Ranch, where street names like Andesite Rd and Zeolite Cir reflect the geological character of the Great Basin. Agricultural infrastructure remains prominent in the south, where the West Walker River feeds a network of water management features including the Alkali Ditch, Swager Ditch, and Wiley Ditch. This era shows a mix of recreational geography near the shoreline and established ranching operations like Fairfield Ranch, alongside natural springs such as Virgil Connell Spring.
