Modoc National Forest encompasses the high volcanic plateaus and valleys shown in this 1990 provisional survey. The landscape is defined by its water management systems and natural springs, crucial for ranching and forest maintenance. To the south, the expansive Big Sage Reservoir dominates the basin, while the Dorris Brothers Reservoir and Ingall Swamp characterize the central drainage. This map documents a series of critical watering points, such as Whittemore Spring, Logan Spring, and several stock tanks including the Timbered Mountain Stock Tank and DeCamp Stock Tank. The relief is marked by Timbered Mountain and the distinct Porcupine Rim overlooking Williams Valley. These features reflect the area's long-standing utility for grazing and resource management within the high desert environment of Northeastern California.
