1968 Map of Coleman Lake

About this map

Coleman Valley and the Warner Valley converge in this high-desert basin of Lake County, where seasonal water and alkaline flats dictate the landscape. The 1968 survey reveals a terrain defined by its water management and natural springs, notably Coleman Lake and the Greaser Reservoir. A network of isolated resources supports ranching and survival in this arid environment, including named features like Kuhaya Waterhole, Foskett Spring, and Twentymile Slough. Evidence of human utility appears in the form of a remote Landing Strip, scattered Gravel Pits, and a lone Prospect mark. The map's detail preserves the placement of numerous family-named and utilitarian springs, such as Terry Spring, Jenny Spring, and Jackass Spring, which represent the vital lifelines for the region's early residents and travelers.
