1961 Map of Leach Hot Springs

About this map

Leach Hot Springs serves as a geothermal focal point in this high-desert landscape, where the basin of Grass Valley meets the rising terrain of the Sonoma Range. The map reveals a post-war ranching and mining economy defined by isolated outposts like Clear Creek Ranch and Hot Springs Ranch. Water management is critical for survival in this arid environment, evidenced by named features such as Lower Grand Trunk Reservoir and a network of desert springs including Grand Trunk Spring and Manganese Spring.
