About this map

Sequoia National Forest and the Toowah Range dominate this early 20th-century survey of the eastern Sierra Nevada. The terrain is defined by a high-altitude network of meadows and water bodies, including Kern Lake and the Chagoopa Plateau, before the landscape drops sharply into the Owens Valley. Along the eastern edge, the Southern Pacific System railroad and the Mojave (Owens Br) line trace the shoreline of Owens Lake, connecting early settlements like Olancha, Cartago, and Carthage.

High-country travel is documented via routes such as the Western Divide and passes like Army Pass and Siberian Pass. For researchers, the map identifies specific early encampments and geothermal features such as Funston Camp, Jordan Hot Sprs, and Soda Sprs. The presence of Big Trees and Lookout Mtn highlights the region's early importance for both natural resource management and recreational exploration during this period of western expansion.
