2012 Map of Mammoth Pool Dam

About this map

The San Joaquin River defines the canyon landscape of this Fresno County high country, dominated by the massive Mammoth Pool Reservoir and the Mammoth Pool Dam. This 2012 survey illustrates the recreational infrastructure established along the river's course, including Wagners Mammoth Pool Resort and numerous forest service sites like Logan Meadow Campground and China Bar Campground. The geography is shaped by high-elevation meadows and peaks, with Fuller Meadow and Summit Meadow providing open breaks in the timbered slopes. Transportation in this vertical terrain relies on Mammoth Pool Rd and Stump Springs Rd, which connect remote outposts and lookout points. Geographically isolated water features, such as Upper Horsethief Lake and Lower Horsethief Lake, sit tucked away from the main river valley, while landmarks like Mile High Curve and Jump Off Point highlight the dramatic relief of the Sierra Nevada foothills.
