About this map

Modoc National Forest encompasses this high-elevation landscape in Modoc County, where water management is central to the terrain's utility. The presence of features like the Dorris Brothers Reservoir and Big Sage Reservoir, alongside numerous stock tanks such as the Timbered Mountain Stock Tank and DeCamp Stock Tank, reveals a geography shaped by ranching requirements. Water flows are carefully tracked through Logan Slough, which meanders across the eastern half of the map.

Prominent landforms define the western and southern reaches, including the heights of Timbered Mtn and the steep incline of Porcupine Rim. Between these elevations, lowlands like Williams Valley and Graves Valley provide relatively level ground, while Whittemore Ridge and Crowder Flat serve as transit corridors. Several natural water sources, including Whittemore Spring and Cow Head Spring, dot the map, providing essential resources in an otherwise arid environment.
