About this map

Karlo sits along the Southern Pacific railroad line, serving as a focal point for this high-desert landscape in Lassen County. The 1950s terrain is defined by the massive volcanic bulk of Snowstorm Mountain and the seasonal expanse of Horse Lake to the west. Evidence of early twentieth-century ranching and infrastructure is scattered throughout the region, from the Snowstorm Ranch near the center of the sheet to the Highway Maintenance Station and an Air Strip further east.

Water management is vital in this arid basin, as shown by the network of developed springs and wells such as Butte Well, Shaffer Well, and Rye Patch Spring. To the southeast, the State Game Refuge occupies a portion of the valley floor, while family-named features like Tunison Mtn and Mapes Spr provide valuable geographic markers for genealogists tracing the early settlers and stockmen of the High Sierra's eastern slope.
