About this map

Devils Postpile National Monument anchors the southern boundary of this 1994 survey, protecting unique geological formations where the Middle Fork of the San Joaquin River flows through the High Sierra. The landscape is a complex corridor of volcanic peaks and glacial lakes, including the basaltic columns of the monument and the notable summits of Mammoth Mtn and San Joaquin Mtn. Settlement is primarily seasonal and recreational, centered on sites like Agnew Meadows and Soda Springs, which serve as staging points for the Pacific Crest National Scenic Trail and the John Muir Trail.

Recreational development is prominent along the eastern slopes, where numerous ski lifts and a gondola climb toward the peak of Mammoth. To the north, June Mountain and Carson Peak overlook a dense network of alpine water bodies like Yost Lake and Fern Lake. The map also captures infrastructure supporting this high-elevation transit, from the Mono Lake Mammoth Road to the remote Ranger Sta and various pack stations.
