On December 30, 1823, Brevet Captain Jose Romero led an expeditionary military expedition finding a route to Tucson from San Gabriel passes in the foothills west of Thermal and Martinez Indian Village (South of Thermal).[citation needed] Thermal (originally Kokell)[8]: 114 began as a railroad camp in 1910 for employees of theSouthern Pacific Railroad, followed byMecca (originally called Walters) in 1915 and Arabia in between, each with about 1,000 residents. Permanent dwellings were soon established on Avenue 56 (renamed Airport Boulevard), formerU.S. Route 99 (State Route 86) andState Route 111 by the 1930s.
Agricultural development from canal irrigation made the area thrive in greenery by the 1950s, followed by the former Camp Young U.S. Naval Air station converted into Thermal Airport by 1965. In the early 1990s, a four-lane highway (State Route 86) was constructed over an earlier transportation route. There is a proposal for a major commercial aviation Airport known as theJackie Cochran-Desert Cities Regional Airport on the same site.
According to theUnited States Census Bureau, the CDP covers an area of 9.5 square miles (25.5 km2), all of its land.[9]
