Modoc National Forest

Modoc National Forest is one of the largest national forests in California, covering about 1.65 million acres across the state's northeastern interior. Spanning portions of Modoc, Lassen, and Siskiyou counties, the forest sits in a remote high-desert region marked by ancient lava flows, broad plateaus, sagebrush foothills, and the rugged Warner Mountains. Much of the forest developed on basalt and other volcanic substrates laid down by lava flows over the past half-million years, which gives the landscape its distinctive rocky soils and basins. The eastern portion rises into the Warner Mountains, where elevations climb high enough to support coniferous forests of pine and fir that contrast sharply with the drier lowlands to the west. The forest is notable both for its sheer size relative to the sparsely populated region around it and for the ecological diversity created by its elevation gradients. It also sits within the traditional homeland of the Modoc people and contains designated wilderness, old-growth stands, and habitat for sagebrush steppe wildlife, making it an important conservation landscape in the western United States.
