Alturas is located at the confluence of the south and north forks of thePit River, east of the center of Modoc County,[7] at an elevation of 4,370 feet (1,330 m).[5] Alturas is one of the largest cities in the region and a local economic hub.
Alturas occupies what was initially anAchumawi (Pit River) village known as Kosealekte[8] or Kasalektawi.[9] The city was initially known asDorris Bridge orDorris' Bridge, named after Pressley and James Dorris, who built a bridge across the Pit River at this location.[7]
The Dorris Bridge post office opened in 1871.[7] The town was renamedDorrisville in 1874[10] and Alturas in 1876, the latter meaning "heights" in Spanish.[11] The census of 1880 showed a population of 148. However, settlement continued over the next two decades, until the city wasincorporated on September 16, 1901. Because of its central location, Dorrisville became the county seat whenModoc County formed in 1874, even though bothAdin andCedarville were then larger towns.[10]

Alturas is the headquarters to theModoc National Forest, the Applegate Field Office of theBureau of Land Management, theModoc National Wildlife Refuge and other recreation areas, and is the trade center for the agricultural region, which produces beef, sheep, potatoes, alfalfa and lumber. Despite its abundance of wilderness, recreational opportunities, hunting and fishing resources, and natural environment, tourism is not a major sector of the local economy – largely due to the city's remote location.[citation needed]
Local, State, Federal, and Tribal governments are the largest employers in Alturas.[23] A vibrant timber industry collapsed in the early 1980s due to increased production costs and low market prices for softwood lumber.
