El Cajon, California:
El Cajon (/ɛlkəˈhoʊn/; Spanish: [elkaˈxon]) is a city in San Diego County, California, United States, 17 mi (27 km) east of Downtown San Diego. The city, located in a valley surrounded by mountains, has acquired the nickname of “The Box.”[7] Its name originated similarly, from the Spanish phrase “el cajón,” which means “the box” or “the drawer.”
El Cajon, Spanish for “the 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 “El Cajon.”
