Counties on California's Eastern Border
According to the 2010 census, the population of the easternmost counties of California was 5,129,384. However, a single metropolitan area, consisting of San Bernardino and Riverside counties, has a population of 4,224,851.
Culture and history
Most of Eastern California does not fit the stereotypes of California and is more related in culture to southeastern Oregon, northwestern Nevada, and western Arizona. Northeastern California is very sparsely populated (except for the area around Lake Tahoe) and tends to be politically conservative, much like the rest of the rural Western United States. However, the counties of San Bernardino and Riverside form the 12th largest metropolitan area of the United States, and the counties of El Dorado, Placer, and Nevada are part of the Greater Sacramento area and are culturally influenced by their respective metropolitan areas.
Historically, Northeastern California has had strong ties to Nevada, with the exact boundary between the two states in some dispute. Residents of portions of near Susanville, California, tried to break away from California in 1856, first by declaring themselves part of the Nataqua Territory and then through annexation to Nevada. The two states further squabbled over ownership of Susanville in 1863. The town of Aurora, Nevada, was temporarily the county seat of both Mono County, California, and Esmeralda County, Nevada. Finally, the line between the two states was settled by a survey in 1872.
The easternmost counties of California are (from north to south) :
Cities within this region include San Bernardino, Riverside, Ontario, Rancho Cucamonga, Roseville, Victorville, Temecula, Palm Springs, Lincoln, El Centro, Barstow, South Lake Tahoe, Susanville, Truckee, Grass Valley, Placerville, and Alturas
Because Eastern California is generally in the rain shadow of the Sierra Nevada or the Transverse Ranges, the climate is extremely dry and can be considered a desert. Indeed, the hottest and lowest area in North America lies in Eastern California: Death Valley.
