Alturas serves as the focal point for this section of Northern California, where the high desert plateau meets the eastern edge of the Modoc National Forest. The landscape is defined by its extensive water management system, featuring numerous high-altitude catchments like the Big Sage Reservoir and the combined Raker and Thomas Reservoirs. To the west, Mahogany Ridge overlooks a series of springs and seasonal drainages, including Kelley Springs and Indian Spring Reservoir. The southern portion of the map transitions into the residential outskirts of town, evidenced by Daphnedale Park and a dense network of local roads named for regional wildlife, such as Sage Hen Ln and Chukar Ln. This network of reservoirs and springs illustrates the vital role of water distribution in this arid timber and rangeland environment.
