Etymology of San Diego County Place Names

Alta. The adjective means ‘high’ in Spanish and is found in many place names. Most of these, such as Altaville, Alta Loma, Alta Peak, Altamont, were applied in American times.

  • Loma Alta is a mini-subdivision, street and park located within Santa Fe Hills

Anza Desert State Park [San Diego]. Named in 1933 in honor of Juan Bautista de Anza, leader of the famous expedition which crossed the area in 1744.

Arroyo, a-roi’-oh. California has more than 150 streams and gulches which include in their names this word, which means ‘watercourse’.

Auga, ah’-gwa. The Spanish word for water was frequently used as a generic geographical term for springs, creeks, and ponds. The most common, agua caliente, for warm springs, has survived in a number of places. Other adjectives used with the term are amargosa (bitter), dulce (sweet), fria (cold), hedionda (stinking), mansa (gentle), tibia (tepic).

Borego [San Diego]. The Spanish word for lamb or sheep was frequently used for place names in Spanish times. The feminine form borrega was used more often than the masculine form, properly spelled borrego.

Buena Vista, bway-na vis-ta. The California places were apparently all named because they command a ‘beautiful view’, not to commemorate Taylor’s victory at Buena Vista.

Cal-. The first syllable of California is found in a number of coined border names. Calada, Calvada, Calneva are found along the Nevada line. Calor connects with Oregon (Caldor in El Dorado County, however, stands for California Door Company), Calzona with Arizona, Calexico with Mexico.

California. California, like El Dorado, Quivira, and The Seven Cities of Cibola, was the name of one of the utopias which originated in the imagination of the people after the discovery of America had revived the age-old dream of a paradise on earth. The mythical realm was apparently created by the Spanish writer Montalvo in the romance Las Sergas de Esplandian (the exploits of Esplandian) and endowed with beautiful black Amazons, gold and pearls.

The name is a fanciful creation; none of the many explanations of the meaning of California can be substantiated. Golfo de la California and a Cabo California appear on maps of 1562. In 1569 the name was applied to the peninsula of what is now Lower California; on later maps it was often extended to include the entire Pacific coast. From 1769 to 1846 the area which is approximately included in the present state was termed Alta (upper), or Nueva (new), California.

Camino, ka-mee’-noh. The Spanish word for ‘road’ is repeatedly found in California place names. El Camino Real (the public highway) is the modern highway along the route which connected the various missions along the coast. It is often erroneously interpreted to mean ‘the king’s highway.’

  • Camino Del Sol and Camino Magnifico are street names in Santa Fe Hills.

Campo. The word means ‘field’ in Spanish but in California is usually used in the sense of ‘camp’.

Cañada. The Spanish word for valley, unlike the terms canyon and arroyo, has not entered our language. In a few places the name has survived from Spanish times, and American surveyors have used the term for gulches and valleys in Ventura and Santa Barbara counties. On the topographical maps of the War Department the Spanish spelling, cañada, has been restored. The pronunciation varies in different parts of the state: ca’-na-da, ca-na’-da, can-yah’-da.

Carlsbad [San Diego]. Named in 1886 after the famous German Karlsbad in Bohemia because the mineral waters found in the two places are similar in composition.

Casa. The place names which contains the Spanish word for house were probably all applied in American times. Casa Blanca [Riverside] was so named by the Santa Fe in 1887 because a white house could be seen from the station.

Cerro. The Spanish generic term for peak or hill is still used in the southern part of the state for peak: Cerro Alto, Cerro Gordo, Cerro San Luis Obispo, etc.

Cleveland National Forest. Created and named July 1, 1908, for President Cleveland, who had died a week before.

Coches Canyon, koh’-ches [San Diego]. The name, ‘hog canyon,’ is derived from the name of the land grant, ‘Cañada de los Coches, of 1843. The Mexican provincial word coche, for ‘hog’, was applied elsewhere in Spanish California.

Cuyamaca, kwee-a-mah’-ka [San Diego]. A rancheria, spelled Cullamac and Cuyamac, is mentioned in mission records after 1776. In 1845 the present spelling was used for a land grant and for the mountains. The designation “Queermack,” commonly used for the mountains, seems to indicate that Diegueño India ekwi-amak (rain above) may be connected with the name.

Del Mar [San Diego]. The name was suggested in 1885 by Bayard Taylor’s poem “The Fight of Paso del Mar.”

Descanso, des-kan’-soh [San Diego]. The name, meaning ‘repose’ in Spanish, was applied to the post office in 1880’s. A place named Descanso, across the border in Lower California, was recorded in 1845.

Encinitas, en-si-nee’-tas [San Diego]. Settled in the 1880’s and named after Cañada de los Encinitos (valley of the little oaks), recorded in 1839. Encina (live oak) and its diminutive, encinita, are frequent in California place names.

La Jolla, hoy’-a [San Diego]. The word, also spelled Joya or Hoya (hollow, cavity, pit, or river bed), is a Mexican geographical term, repeatedly found in Spanish California documents and maps. The name in San Diego County was probably first applied to a hollow, or to a rancheria ‘in the hollow’; it appears in mission and land-grant records since 1828, and was applied to the town in 1869.

La Mesa [San Diego]. The name was first used in 1886 as Las Mesa Heights.

Monte. The word means ‘grove,’ ‘thicket,’ or ‘woods’ in Spanish and is sometimes used to form pleasant-sounding but ungrammatical combinations for place names, like Monte Rio, Monte Vista, Miramonte. Although Spanish dictionaries list monte aso with the meaning ‘mountain,’ it has rarely if ever been used as a geographical term with that meaning in Spanish-speaking countries.
