About this map

Sierra National Forest surrounds the engineering feat of the Mammoth Pool Dam, which impounds the Mammoth Pool Reservoir along the San Joaquin River drainage. This high-elevation landscape in Fresno and Madera counties is defined by a dense network of forest service spurs and specialized routes, including the Stump Springs Road and the Minarets Rd. The topography is marked by several alpine meadows such as Logan Meadow, Fuller Meadow, and Aspen Meadow, which provide breaks in the timbered slopes.

Water management and recreation are central to the area's layout, with the reservoir being fed by numerous tributaries including Chiquito Cr and Jackass Cr. Farther south, the terrain ascends toward Kaiser Ridge, passing landmarks like Lookout Point and the high-altitude Upper Horsethief Lake. The presence of Westfall Camp and numerous named spurs like Mill Creek Spur and Guards Spur indicates a landscape heavily utilized for forest management and seasonal access.
