About this map

The high desert landscape of Madeline Plains defines this portion of Lassen County, where water management is central to the local geography. Significant infrastructure for livestock or irrigation is evident through features like Van Loan Reservoir, Threemile Reservoir, and Mendiboure Reservoir. Small settlements such as Brockman and Moran sit along the western edge, positioned near the drainage of Van Loan Cr.

Rising above the plains, the terrain becomes increasingly complex to the east, marked by the heights of McDonald Peak, Olson Mtn, and the distinct Three Peaks. This 2015 survey illustrates a network of springs, including Big Springs and Wire Spring, which sustain life in the arid basins between Skeleton Flat and Threemile Canyon. The map provides a clear view of how high-altitude water sources like Lanning Spring and Poulsen Spring are distributed across the volcanic topography of the Modoc Plateau region.
