About this map

Modoc National Forest dominates this northern California landscape, characterized by an extensive network of water management features and high desert terrain. The area is defined by massive catchment systems, notably the Big Sage Reservoir and the Raker and Thomas Reservoirs, which underscore the region's reliance on managed water resources. Historically significant pathways, such as the Old Emigrant Trl, weave through the topography near Mahogany Ridge and Hog Ridge, marking routes used by early settlers.

Concentrated residential development appears at Daphnedale Park and the northern edge of Alturas, where a grid of modern street names—many inspired by local wildlife like Mule Deer, Gray Wolf, and Partridge Ln—meets the rugged canyons of Swanson Canyon and Daggert Canyon. This survey captures the transition from high-altitude rangeland and spring-fed basins like Indian Spring and Kelley Springs to the established administrative seat of Modoc County.
