Imperial County (

San Diego County
.

Imperial County is located in the far southeast of California, in the

border region, the smallest but most economically diverse region in the state.[12]

Although this region is a desert, with high temperatures and low average rainfall of 3 inches (76 mm) per year,[13] the economy is strongly based on agriculture. This is supported by irrigation, with water supplied wholly from the Colorado River via the All-American Canal.[14]

The Imperial Valley straddles the border between the United States and Mexico. Imperial County is strongly influenced by Mexican culture. Approximately 80% of the county's population is Hispanic, with the vast majority being of Mexican origin. The remainder of the population is predominantly non-Hispanic white, in addition to smaller African American, Native American, and Asian minorities.

History

Juan Bautista de Anza's noted expedition passed through the area in 1775.

The indigenous peoples of the area were the Quechan along the Colorado River, the Kamia-Kumeyaay west of the Quechan, and the Cahuilla to the north.

Spanish explorer Melchor Díaz was one of the first Europeans to visit the area of the Imperial Valley in 1540. The explorer Juan Bautista de Anza also explored the area in 1776.[15] The indigenous peoples in the county were also engaged in an armed regional conflict, with the Quechan leading a coalition with the Kumeyaay against the Maricopa-led coalition with the Cahuilla, Cocopah, and other tribes in modern-day Arizona. Constant warfare would deny the Spanish explorers any overland access to Alta California, dispites Spanish attempts to mediate the conflict.[16]

Decades later, after the Mexican–American War, the northern half of the valley was annexed in 1848 by the U.S., while the southern half remained under Mexican rule.

Following the war, another war would consume the region in 1850 after the

Glanton Gang sabotaged Quechan ferry operators and mugged a local Quechan chief. This would lead towards the start of the Yuma War, with a Quechan-led coalition of tribes against the US army and their indigenous allies in Baja California and Sonora. In the First Yuma War, the Quechan laid siege on Fort Yuma in 1851, and forced the American garrison there to abandon the fort. The Americans returned to the area in 1852 and subdued the Quechan by destroying their villages and farmland, and killed any warriors that resisted, leading to Quechan surrender to the US.[17]
The Second Yuma War would later see neighboring tribes erode much of the military advantages that the Quechan had left.

Small-scale settlement in natural aquifer areas had occurred in the early 19th century (the present-day site of Mexicali), but most permanent settlement was after 1900.[18]

In 1905, torrential rainfall in the American Southwest caused the Colorado River (the only drainage for the region) to flood, including canals that had been built to irrigate the Imperial Valley. Since the valley is partially below sea level, the waters never fully receded, but collected in the Salton Sink in what is now called the Salton Sea.

Imperial County was formed in 1907 from the eastern portion of San Diego County. The county was named for Imperial Valley. This had been named for the Imperial Land Company, a subsidiary of the California Development Company, which at the turn of the 20th century had claimed the southern portion of the Colorado Desert for agriculture.[19] The Imperial Land Company also owned extensive lands in Mexico (Baja California). Its objective was to develop commercial crop farming.

By 1910, the land company had managed to settle and develop thousands of farms on both sides of the border. The Mexican Revolution soon after severely disrupted the company's plans. Rival Mexican armies affiliated with different ethnicities killed nearly 10,000 farmers and their families in northern Mexico. Not until the 1920s was the other side of California in the United States sufficiently peaceful and prosperous for the company to earn a return for a large percentage of Mexicans. Some chose to stay and create roots in newly developed communities in the valley.

During the

All American Canal was completed from its source, the Colorado River
, to Imperial Valley from 1948 to 1951. By the 1950 census, more than 50,000 residents lived in Imperial County alone, about 40 times the population of 1910. Most of the population was year-round, but would increase every winter by migrant laborers from Mexico. Until the 1960s, the farms in Imperial County provided substantial economic returns to the company and the valley.

During the Great Recession of 2008–11, El Centro had one of the highest unemployment rates (above 30–34%) in the U.S. In the early 2020s, Imperial ranks as one of California's poorest counties. It has a lower median household income than either the state or national medians.[20]

Colorado River

The Colorado River streams through the southwestern United States and northwestern Mexico, approximately 1,450 miles (2,330 km) long, draining a part of the arid regions on the western slope of the Rocky Mountains. The natural course of the river flows from north of Grand Lake, Colorado, into the Gulf of California. For many months out of the year, however, no water actually flows from the United States to the gulf, due to human use.[26] The river is a popular destination for water sports, including fishing, boating, water skiing, and jet skiing.[27]

Fossil Canyon and Painted Gorge

Located near Ocotillo, California in the Coyote Mountains, Fossil Canyon (and the surrounding area) is a great place for rock-hounding and fossil hunting. The fossils here are not necessarily of dinosaurs; more commonly found are ancient oyster and seashell, coral, and other marine life from the prehistoric Miocene epoch, when the entire area was submerged as part of the Western Interior Seaway.[29]

The Painted Gorge, located on the eastern side of the Coyote Mountains, consists of

metamorphic and igneous rock; Heat and movement over time has created fantastic shapes and colors. Dark ochre, iron-reds, royal purples, and mauves (mixed with dark browns/black) create a palette of color as the sun illuminates and plays shadows upon this geologic wonder.[30]

Imperial NWR

Mesquite Point at Imperial NWR

The Imperial National Wildlife Refuge protects wildlife habitat along 30 miles (50 km) of the lower Colorado River in Arizona and California, including the last un-channeled section before the river enters Mexico. The river and its associated backwater lakes and wetlands are a green oasis, contrasting with the surrounding desert mountains. It is a refuge and breeding area for migratory birds and local desert wildlife.[31]

Sonny Bono Salton Sea NWR

The Sonny Bono Salton Sea National Wildlife Refuge is located 40 miles (64 km) north of the Mexican border at the southern end of the Salton Sea in California's Imperial Valley. Situated along the Pacific Flyway, the refuge is the only one of its kind, located 227 feet (69 m) below sea level. Because of its southern latitude, elevation, and location in the Colorado Desert, the refuge experiences some of the highest temperatures in the nation. Daily temperatures from May to October generally exceed 100 °F (38 °C) with temperatures of 116–120 °F (47–49 °C) recorded yearly.[32]

Museum of History in Granite

The Museum of History in Granite in the town of Felicity exhibits granite monuments made from Missouri Red Granite. Each is 100 feet (30 m) long. Subjects include a Korean War Memorial, History of Arizona, The Wall for the Ages, the eight monument History of Humanity, and the History of the United States of America. Smaller monuments include the Felicity Stone (sm), a Rosetta Stone for the future located at the center of the History of Humanity monuments.

Geography

Fields with Mount Signal in Background

According to the

U.S. Census Bureau, the county has a total area of 4,482 square miles (11,610 km2), of which 4,177 square miles (10,820 km2) is land and 305 square miles (790 km2) (6.8%) is water.[33]
Much of Imperial County is below sea level. Imperial County is roughly twice the size in total square miles as the State of Delaware.

Imperial county is bordered on the north by Riverside County; on the east by Yuma County, Arizona; on the south by Mexico; and on the west by San Diego County. The Colorado River forms the county's eastern boundary. Two notable geographic features are found in the county, the Salton Sea, at 235 feet (72 m) below sea level, and the Algodones Dunes, one of the largest dune fields in America.[34]

The county is in the Colorado Desert, an extension of the larger Sonoran Desert. The Chocolate Mountains are located east of the Salton Sea, and extend in a northwest–southeast direction [34] for approximately 60 miles (97 km).

In this region, the

Economy

Thousands of acres of prime farmland have transformed the desert into one of the most productive farming regions in California with an annual crop production of over $1 billion. Agriculture is the largest industry in Imperial County and accounts for 48% of all employment.[72] Although this region is a desert, with high temperatures and low average rainfall of 3 inches (76 mm) per year, the economy is heavily based on agriculture due to irrigation, which is supplied wholly from the Colorado River via the All-American Canal.[13]

Irrigation Canal Imperial County

A vast system of canals, check dams, and pipelines carry the water all over the valley, a system which forms the Imperial Irrigation District, or IID. The water distribution system includes over 1,400 miles (2,300 km) of canal and with 1,100 miles (1,800 km) of pipeline.[14] The number of canal and pipeline branches number roughly over a hundred. Imported water and a long growing season allow two crop cycles each year, and the Imperial Valley is a major source of winter fruits and vegetables, cotton, and grain for U.S. and international markets. Alfalfa is another major crop produced in the Imperial Valley.[73] The agricultural lands are served by a constructed agricultural drain system, which conveys surface runoff and subsurface drainage from fields to the Salton Sea, which is a designated repository for agricultural runoff.[74] Imperial County produces nearly 2/3 of all vegetables consumed by Americans during the winter.[75]

El Centro is the commercial center of Imperial County. Fifty percent of the jobs in El Centro come from the service and retail sector.[72]

A recent growth in the interest of Imperial County as a filming location, has spurred growth in servicing this industry.

Los Angeles, California, movies are sometimes filmed in the sand dunes outside the agricultural portions of the county. These have included Return of the Jedi, Stargate, The Scorpion King, and Into the Wild. Additionally, portions of the 2005 film Jarhead were filmed here because of its similarity to the desert terrain of Iraq.[citation needed

In 2016, Imperial County had the highest unemployment rate of any county in the United States, at 23.5%.[76]

Cotton in Imperial County and Riverside is predominantly Bt cotton.[77]: Supplemental  This is in contrast to the rest of the state, which largely relies on non-incorporated pesticides.[77]: Supplemental  The introduction of Bt cotton has dramatically reduced pesticide use here.[77]: Supplemental 

Renewable energy

Imperial Valley has become a hotbed of renewable energy projects, both solar and geothermal.

solar thermal plants, 10 square miles (26 km2) with 38,000 "sun catchers," it will power up to 600,000 homes once it is fully operational by around 2015.[79][78] CalEnergy runs a geothermal plant that generates enough power for 300,000 homes and could tap into more for up to 2.5 million homes.[78]
