Region Summary

Modoc County is a county located in the far northeast corner of the U.S. state of California. As of the 2010 census, the population was 9,686.[1] making it the third-least populous county in California. The county seat and only incorporated city is Alturas.[2] Previous county seats include Lake City and Centerville; the latter is now a ghost town. The county borders Nevada and Oregon.

A large portion of Modoc County is federal land. Several federal agencies, including the United States Forest Service, Bureau of Land Management, National Park Service, Bureau of Indian Affairs, and the United States Fish and Wildlife Service,
have employees assigned to the area, and their operations are a
significant part of the economy and services in this rural area.

The county’s official slogans include, “The last best place,” and “Where the West still lives.”

Topography & Vegetation

The county is very diverse geographically. The northwestern edge of the county is dominated by the Medicine Lake Highlands, the largest shield volcano on the U.S. West Coast. The Lava Beds National Monument lies partly within the northwest corner of the County. Also along the western edge of the county is the massive Glass Mountain lava flow. The southwestern corner of the county is a unique ecosystem of isolated hardwoods (oaks) and volcanic mountains with inter mountain river valleys.

A great diversity of plants are found in Modoc County, since this is situated within the biodiverse California Floristic Province. Numerous native trees are found in the county including Garry Oak and Washoe Pine trees.[11] Jeffrey Pine and Ponderosa Pine are also found in large numbers.[12]
