About this map

The Southern Pacific railroad corridor defines the development of this high-desert landscape in Lassen County, running through the heart of the Secret Valley. The small settlement of Karlo serves as a focal point along the tracks, supported by a Water Tank and a nearby Air Strip, reflecting the logistical needs of mid-century transportation and land management. Further north, the Snowstorm Ranch sits at the base of Snowstorm Mountain, illustrating the historical ranching patterns of the region.

Water is the critical resource here, with numerous small springs like Spanish Springs and Rye Patch Spring punctuating the arid terrain. The eastern edge of Horse Lake dominates the western portion of the map, while the expansive State Game Refuge indicates the area's transition into conservation during the 1950s. Traceable features such as a small Cem and a Highway Maintenance Station provide specific touchpoints for local historians and genealogists studying this remote corner of California.
