About this map

Modoc National Forest dominates this landscape, where high-altitude water management and livestock infrastructure define the terrain. The northern reaches of the Big Sage Reservoir anchor the southern boundary, while the Dorris Brothers Reservoir highlights the importance of water storage in this arid timberland. The map reveals a complex system of hydrology and range improvements, featuring named stock tanks like the Timbered Mountain Stock Tank and DeCamp Stock Tank positioned along the slopes of Timbered Mountain.

Transit through the region follows the historical path of the Crowder Flat Road, which cuts across the drainage of Ingall Swamp. Local geography is marked by distinctive features such as Whittemore Ridge and the Porcupine Rim, providing a detailed look at the grazing and forest management patterns of the late 20th century. Numerous isolated water sources, including Whittemore Spring and Cow Head Spring, trace the natural seeps that have historically supported seasonal use in this part of California.
