About this map

Warner Valley serves as the focal point for this late 1960s survey of the high desert landscape in Lake County. The map captures a complex network of springs and seasonal water sources that supported early ranching efforts, most notably at the Barry Ranch in the northeast. Water management is central to the area's development, anchored by the Priday Reservoir and its spillway, alongside numerous named springs such as Finnucane Spring, Lynch Spring, and Cleland Spring. These features suggest a landscape where life and labor followed the reliable presence of water.

The eastern edge is dominated by the dramatic margins of the Warner Lakes system, including portions of Hart Lake and Crump Lake. Between these basins and the western uplands, where Fish Lake and Bull Lake are situated, the terrain is marked by remote tracks like the Jeep Tr, indicating the difficulty of travel across these volcanic formations. This survey reflects a specific moment in the mid-20th century before significant modern infrastructure altered the local hydrology.
