About this map

The Fort Bidwell Indian Reservation and the town of Fort Bidwell anchor the southern reaches of this map, where the high desert meets the base of the Warner Mountains. This late-twentieth-century study of the corner where California and Oregon meet reveals a landscape defined by historical extraction and alpine water management. A high concentration of mining sites, including the Moonlight Mines, Sunshine Mine, and Klondyke Mines, are scattered across the northern slopes, signaling the region’s enduring mineral interest.

Water distribution in the arid Surprise Valley is visible through the engineering of the Schadler Ditch and the Burger Reservoir. The rugged transition from Mt Vida down to O'Leary Flat shows the complex terrain that separated these early industrial operations from the settlements below. This map is particularly valuable for tracing the physical footprint of mining claims and the specific topography of the reservation during this period.
