Thermal's Story: A Brief History

Thermal started as a camp for railroad workers in 1910. It was first called Kokell. Over time, more people moved in and built homes.

Growing with Agriculture and Aviation

By the 1950s, the area became green and fertile thanks to irrigation canals. This helped farming grow a lot. Later, a former U.S. Naval Air station became the Thermal Airport in 1965. In the early 1990s, a new four-lane highway, State Route 86, was built. There are plans for a major airport, the Jackie Cochran-Desert Cities Regional Airport, at the same site.

The Thermal Club: A Place for Race Cars

The Thermal Club is a special place for car enthusiasts. It's a private motorsports racetrack and club south of the airport. It opened in 2012. In 2024, it hosted a big IndyCar Series race.

Where is Thermal? Geography and Climate
