El Cajon ( EL-_--hohn Spanish: El Cajón, meaning "the box") is a city in San Diego County, California, United States, 17 mi (27 km) east of Downtown San Diego. The city takes its name from Rancho El Cajón, which was in turn named for the box-like shape of the valley which surrounds the city, which is also the origin of the city's common nickname of "The Box".


El Cajon, Spanish for "the big box," was first recorded on September 10, 1821, as an alternative name for sitio rancho Santa Mónica to describe the "boxed in" nature of the valley in which it sat. The name appeared on maps in 1873 and 1875, shortened to "Cajon," until the modern town developed in which the post office was named "Elcajon."

In 1905, the name was once again expanded to "El Cajon" under the insistence of California banker and historian, Zoeth Skinner Eldredge.

Geography and climate

El Cajon is located at 32°47′54″N 116°57′36″W / 32.79833°N 116.96000°W / 32.79833; -116.96000 (32.798300, -116.960055). According to the United States Census Bureau, the city has a total area of 14.4 square miles (37 km2), all land. It is bordered by San Diego and La Mesa on the west, Spring Valley on the south, Santee on the north, and unincorporated San Diego County on the east. It includes the neighborhoods of Fletcher Hills, Bostonia, and Rancho San Diego.

Under the Köppen climate classification system, El Cajon straddles areas of Mediterranean climate (CSa) and semi-arid climate (BSh). As a result, it is often described as "arid Mediterranean" and "semi-arid Steppe". Like most inland areas in Southern California, the climate varies dramatically within a short distance, known as microclimate. El Cajon's climate has greater extremes compared to coastal San Diego. The farther east from the coast, the more arid the climate gets, until one reaches the mountains, where precipitation increases due to orographic uplift.

El Cajon's climate is warm during summer with mean temperatures averaging 70.1 °F (21.2 °C) or higher and cool during winter with mean temperatures averaging 55.4 °F (13.0 °C) or higher.

The warmest month of the year is August with an average maximum temperature of 88.1 °F (31.2 °C), while the coldest month of the year is December with an average minimum temperature of 40.3 °F (4.6 °C).

Temperature variations between night and day tend to be moderate with an average difference of 24 °F (13 °C) during the summer, and an average difference of 26 °F (14 °C) during the winter.

The annual average precipitation at El Cajon is 11.96 inches (30.4 cm). Rainfall is fairly evenly distributed throughout the winter months, but rare in summer. The wettest month of the year is December with an average rainfall of 3.80 inches (9.7 cm).

The record high temperature was 113 °F (45 °C) on June 14, 1917; September 1, 1955; July 22, 2006; and September 27, 2010. The record low temperature was 19 °F (−7 °C) on January 8, 1913. The wettest year was 1941 with 28.14 inches (71.5 cm) and the dryest year was 1989 with 1.51 inches (3.8 cm). The most rainfall in one month was 11.43 inches (29.0 cm) in January 1993. The most rainfall in 24 hours was 5.60 inches (14.2 cm) on January 27, 1916. A rare snowfall in November 1992 totaled 0.3 inches (0.76 cm). 3 inches of snow covered the ground in January 1882.

During Spanish rule (1769–1821), the government encouraged settlement of territory now known as California by the establishment of large land grants called ranchos, from which the English word ranch is derived. Land grants were made to the Roman Catholic Church which set up numerous missions throughout the region. In the early nineteenth century, mission padres' search for pasture land led them to the El Cajon Valley. Surrounding foothills served as a barrier to straying cattle and a watershed to gather the sparse rainfall. For years the pasture lands of El Cajon supported the cattle herds of the mission and its native Indian converts.

It was not until the Mexican era (1821–1846) that titles to plots of land were granted to individuals. The original intent of the 1834 secularization legislation was to have church property divided among the former mission Indians. However, most of the grants were actually made to rich "Californios" of Spanish background who had long been casting envious eyes on the vast holdings of the Roman Catholic missions. In 1845 California Governor Pio Pico confiscated the lands of Mission San Diego de Alcala. He granted eleven square leagues (about 48,800 acres, 197 km2) of the El Cajon Valley to Dona Maria Antonio Estudillo, daughter of José Antonio Estudillo, alcalde of San Diego, to repay a $500 government obligation. The grant was originally called Rancho Santa Monica and encompassed present day El Cajon, Bostonia, Santee, Lakeside, Flinn Springs, and the eastern part of La Mesa. It also contained the 28-acre (0.11 km2) Rancho Cañada de los Coches grant. Maria Estudillo was the wife of Don Miguel Pedrorena (1808–1850), a native of Madrid, Spain, who had come to California from Peru in 1838 to operate a trading business.

With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored. As required by the Land Act of 1851, a claim for Rancho El Cajon was filed by Thomas W. Sutherland, guardian of Pedrorena's heirs (his son, Miguel, and his three daughters, Victoria, Ysabel and Elenain) with the Public Land Commission in 1852, confirmed by the U.S. Supreme Court, and the grant was patented in 1876. In 1868, Los Angeles land developer Isaac Lankershim bought the bulk of the Pedrorena's Rancho El Cajon holdings and employed Major Levi Chase, a former Union Army officer, as his agent. Chase received from Lankershim 7,624 acres (30.9 km2) known as the Chase Ranch. Lankershim hired Amaziah Lord Knox (1833–1918), a New Englander whom he had met in San Francisco, to manage Rancho El Cajon. In 1876, Knox established a hotel there to serve the growing number of people traveling between San Diego and Julian, where gold had been discovered in 1869. Room and board for a guest and horse cost $1 a night. The area became known as Knox's Corners and was later renamed. By 1878 there were 25 families living in the valley and a portion of the hotel lobby became the valley post office with Knox as the first postmaster.

El Cajon was incorporated as a city in 1912.

In the 1960s and 70s, Frontier Town, Big Oak Ranch, was a tourist attraction, featuring a typical frontier town themepark and a periodic simulated shootout. The park closed around 1980 and is being used for residential housing.
