Baja California (English: Lower California) is a state in Mexico. It is the northernmost and westernmost of the 31 states which, with Mexico City, comprises the 32 Federal Entities of Mexico. Before becoming a state in 1953, the area was known as the North Territory of Baja California (El Territorio Norte de Baja California). It comprises the northern half of the Baja California Peninsula plus oceanic Guadalupe Island. The mainland portion of the state is bordered on the west by the Pacific Ocean, on the east by Sonora, the U.S. State of Arizona, and the Gulf of California (also known as the “Sea of Cortez”), and on the south by Baja California Sur. Its northern limit is the U.S. state of California. The state has an estimated population of well above 3,3 million, much more than the sparsely populated Baja California Sur to the south, and similar to San Diego County, California on its north. Over 75% of the population lives in the capital city, Mexicali, in Ensenada, or in Tijuana. Other important cities include San Felipe, Rosarito Beach and Tecate. The population of the state is composed of Mestizos, mostly immigrants from other parts of Mexico, and, as with most northern Mexican states, a large population of Mexicans of European ancestry, and also a large minority group of East Asian, Middle Eastern and indigenous descent. Additionally, there is a large immigrant population from the United States due to its proximity to San Diego and the cheaper cost of living compared to San Diego. There is also a significant population from Central America. Many immigrants moved to Baja California for a better quality of life and the number of higher paying jobs in comparison to the rest of Mexico and Latin America.
Baja California is the twelfth largest state by area in Mexico. Its geography ranges from beaches to forests and deserts. The backbone of the state is the Sierra de Baja California, where the Picacho del Diablo, the highest point of the peninsula, is located. This mountain range effectively divides the weather patterns in the state. In the northwest, the weather is semi-dry and mediterranean. In the narrow center, the weather changes to be more humid due to altitude. It is in this area where a few valleys can be found, such as the Valle de Guadalupe, the major wine producing area in Mexico. To the east of the mountain range, the Sonoran Desert dominates the landscape. In the south, the weather becomes drier and gives way to the Vizcaino Desert. The state is also home to numerous islands off both of its shores. In fact, the westernmost point in Mexico, the Guadalupe Island, is part of Baja California. The Coronado, Todos Santos and Cedros Islands are also on the Pacific Shore. On the Gulf of California, the biggest island is the Angel de la Guarda, separated from the peninsula by the deep and narrow Canal de Ballenas.
Baja California encompasses a territory which exhibits diverse geography for a relatively small area. The Peninsular Ranges of the California cordillera run down the geographic center of the state. The most notable ranges of these mountains are the Sierra de Juarez and the Sierra de San Pedro Martir. These ranges are the location of forests reminiscent of Southern California‘s San Gabriel Mountains. Picacho del Diablo is the highest peak in the whole peninsula. Valleys between the mountain ranges are located within a climate zone that are suitable for agriculture. Such valleys included the Valle de Guadalupe and the Valle de Ojos Negros, areas that produce citrus fruits and grapes. The mineral-rich mountain range extends southwards to the Gulf of California, where the western slope becomes wider, forming the Llanos del Berrendo in the border with Baja California Sur. The mountain ranges located in the center and southern part of the state include the Sierra de La Asamblea, Sierra de Calamajué, Sierra de San Luis and the Sierra de San Borja. Temperate winds from the Pacific Ocean and the cold California Current make the climate along the northwestern coast pleasant year-round. As a result of the state’s location on the California current, rains from the north barely reach the peninsula, thus leaving southern areas drier. South of El Rosario River the state changes from a Mediterranean landscape to a desert one. This desert exhibits diversity in succulent flora species that flourish in part due to the coastal fog. To the east, the Sonoran Desert enters the state from both California and Sonora. Some of the highest temperatures in Mexico are recorded in or nearby the Mexicali Valley. However, with irrigation from the Colorado River, this area has become truly an agricultural center. The Cerro Prieto geothermal province is near Mexicali as well (this area is geologically part of a large pull apart basin); producing about 80% of the electricity consumed in the state and enough more to export to California. Laguna Salada, a saline lake below sea level lying between the rugged Sierra de Juarez and the Sierra de los Cucapah, is also in the vicinity of Mexicali. The state government has recently been considering plans to revive Laguna Salada. The highest mountain in the Sierra de los Cucapah is the Cerro del Centinela or Mount Signal. The Cucapah are the primary indigenous people of that area and up into the Yuma, Arizona area.
There are numerous islands on the Pacific shore. Guadalupe Island is located in the extreme west of the state’s boundaries and is the site of large colonies of sea lions. Cedros Island exists in the southwest of the state’s maritime region. The Todos Santos Islands and Coronado Islands are located off the coast of Ensenada and Tijuana respectively. All of the islands in the Gulf of California, on the Baja California side, belong to the municipality of Mexicali. Baja California obtains much of its water from the Colorado River. Historically the river drained into the Colorado River Delta which flowed into the Gulf of California, but due to large demands for water in the American Southwest, less water now reaches the Gulf. The Tijuana metropolitan area also relies on the Tijuana River as a source of water. Much of rural Baja California depends predominantly on wells and a few dams. Tijuana also purchases water from San Diego County‘s Otay Water District. Potable water is the largest natural resource issue of the state.
