About this map

Geothermal activity and ranching define this high-altitude landscape in Long Valley, where the Owens River and Mammoth Creek intersect. The 1983 survey illustrates a specialized local economy centered around the waters of Whitmore Hot Sprs and the Hot Creek State Fish Hatchery, situated just east of the Mammoth-June Lake Airport. Settlement patterns are sparse, anchored by the Cashbaugh Ranch and the Mono County Youth Camp, while educational infrastructure is represented by the Mammoth Sch near the southwestern corner.

Evaporative features like Big Alkali Lake and Little Alkali Lake suggest a basin where mineral-rich water frequently pools and recedes. Much of the western terrain falls within the Inyo National Forest, transitioning from the flats toward the rising slopes of the Little Antelope Valley. Transportation is dominated by the long reach of Benton Crossing Road, which provides the primary access through these thermal flats and open grazing lands.
