1989 Map of McDonald Peak

About this map

Madeline Plains defines the lower elevations of this Lassen County landscape, where early ranching infrastructure and seasonal water sources are the primary indicators of human activity. The map reveals the location of Mendiboure Ranch and Jones Ranch, along with the small settlement area of Moran. These ranching sites were supported by a network of engineered water features, including Mendiboure Reservoir, Van Loan Reservoir, and Threemile Reservoir, alongside natural springs like Poulsen Spring and Big Springs.
