Starting in the late 1800s mining industry set up around Searles Dry Lake to mine borax. Trona was officially established in 1913, as a self-contained company town, wholly operated by its resident mining company to house employees. Employees were paid in company scrip instead of cash. The mining company also built a library, a scrip-accepting for-profit grocery store, a school, basic housing , and minimal recreation facilities. The Trona Railway was built in 1913–14 to provide the town with a rail connection to the Southern Pacific (now the Union Pacific) line at Searles. The railway still operates today. Economic booms and busts followed. Its most notable boom occurred during World War I, when Trona was the only reliable American source of potash, an important element used in the production of gunpowder. In 1974, the company, now known as American Potash, was bought by Kerr-McGee, who did not want a company town. Their attempts to make everybody leave was resisted by the inhabitants . Today, Searles Valley Minerals Inc.'s soda ash processing plant remains the largest firm in town. Other operations nearby include evaporative salt extraction from the dry lake bed's surface, and a lime quarry. Searles Valley Minerals is the largest employer in Trona, and many employees live in Ridgecrest, California, commuting daily to Trona. Since its heyday, Trona's population has decreased, with more and more services relocating to the nearest town, Ridgecrest. Geography. The same collection of geologic forces which created the Searles Valley where Trona sits also created the natural resource of Searles Dry Lake, which contains rich  deposits of chemicals, including dozens of minerals. Located a few miles to the south are the Trona Pinnacles, an unusual landscape consisting of more than 500 tufa spires, some as high as 140 feet, rising from the bed of the Searles Lake basin. Trona is a seismically active area, and was heavily affected by the 2019 Ridgecrest earthquakes. Trona is located in the Eastern California Shear Zone, a seismically active zone that accommodates up to 25% of the fault movement between the Pacific and North American plates. Climate.

Trona Joint Unified School District operates two schools: Trona Elementary School and Trona High School . There is no junior high or middle school; instead, the high school houses 7th and 8th grades in addition to the traditional 9th through 12th grades. Course offerings at Trona High are supplemented by online classes offered by California State University, Dominguez Hills and Cerro Coso Community College in Ridgecrest, California. 95 students were enrolled at Trona High during the 2014-15 school year and its sports teams compete as the Tornadoes. The school's football field, known as "The Pit," has received national attention from "The New York Times", "Good Morning America", and the "Los Angeles Times" as the  only dirt American football field in the United States — the region’s heat and salty soil make upkeep of a grassy field nearly impossible. Barrow High School in Alaska previously had a dirt field as well, but it was replaced with blue Astroturf in 2007. Trona high school will be closed for a year to repair damage done by a earthquake. In popular culture. A number of Hollywood films have been shot in the surrounding desert (particularly around the Trona Pinnacles), including "" and "Planet of the Apes".
