Where Are the Bonneville Salt Flats?
Quick Answer
The Bonneville Salt Flats are in northwestern Utah, United States, about 190 km west of Salt Lake City — a vast, flat expanse of salt covering about 121 square kilometres, famous as the site where land speed records have been set since 1914.
The Full Story
The Bonneville Salt Flats are the remnant of ancient Lake Bonneville, a massive Pleistocene lake that covered much of western Utah about 14,500-32,000 years ago. As the climate warmed, the lake evaporated, leaving behind thick deposits of sodium chloride (table salt) and other minerals. The result is one of the flattest natural surfaces on Earth: variations of just a few centimetres across kilometres. This flatness, combined with the hard salt surface, makes it ideal for high-speed driving. The first land speed record attempt here was in 1914 (racing driver Teddy Tetzlaff reached 228 km/h). The Bonneville Speedway on the salt flats has hosted hundreds of record attempts; in 1970, Gary Gabelich reached 1,014 km/h in the rocket-powered Blue Flame. Annual events like Speed Week (organised by the Southern California Timing Association since 1949) attract thousands of racers. The salt crust is about 1.5 metres thick in the centre but has been thinning, threatening the site future.
