About this map

Mammoth Lakes and the adjacent settlement of Old Mammoth anchor this early 1980s topographic study of the Eastern Sierra. The map illustrates a period of significant recreational development within the Inyo National Forest, showing an established network of facilities including the Mammoth Visitor Center, Camp High Sierra, and several clustered campgrounds like Pine Glen Group Campground. To the north and east, the landscape transitions into the wide expanse of Long Valley, where the Owens River flows past the Arcularius Ranch.

Geothermal and natural landmarks are prominent, notably Casa Diablo Hot Sprs near the junction of U S Highway 395. The map also preserves local navigation points from the era, such as Lookout Mountain and the Crestview settlement along the highway. For researchers, the inclusion of St Joseph Church and specific civic buildings provides a detailed look at the community footprint before further modern expansion changed the local character.
