route. A segment of the Applegate-Lassen Route, a Nineteenth Century pioneer wagon route to the area, crosses the valley diagonally from north of State Route 299 to Fandango Pass. The route is also known as the California National Historic Trail. Other roads out of the valley are unpaved. Because of its location along the Nevada state line, it is normal to see patrol cars from the Nevada Highway Patrol and the Washoe County Sheriff's Department transiting the area. Telecommunications Wired telephone service in this part of area code 530 appears to work out of a single central office and is provided by Frontier Communications. There is wireless service to some areas of the valley. This is a remote area and services that people from cities expect are sometimes degraded, expensive, or unavailable. The valley is one of the last places in California where Department of Transportation (Caltrans) highway workers have no radio communications coverage. California Highway Patrol radios were mostly useless in the area until the 1980s installation of a remote-controlled base station intended to cover the valley. The unvoted base station works over a 76 MHz link to establish radio connectivity from the Highway Patrol's command center to this remote area. Indian tribal governments There are two sovereign tribal governments in the valley: The Cedarville Rancheria and the Fort Bidwell Indian Community of the Fort Bidwell Reservation of California. The Cedarville Rancheria is a Paiute community on the southwest edge of Cedarville; it is led by Chairwoman Virginia Lash. The larger Fort Bidwell Paiute community is located at the Fort Bidwell Reservation to the north, and is led by Chairman Aaron Townsend. Special districts The area is entirely inside the Modoc County Air Pollution Control District. It is served by K-through-12 provider Surprise Valley Joint Unified School District headquartered in Cedarville. The Surprise Valley Hospital District, also known as Surprise Valley Healthcare District, operates a clinic in Cedarville. Cedarville Water District exists in Cedarville.
