The Bonneville Salt Flats are located west of the Great Salt Lake in Utah. They cover about 30,000 acres and are open to the public. The flats are made up of salt deposits that were left behind by an ancient lake that once covered the area. The salt is about 10 feet deep in places.
The flats are a popular spot for speed trials, as the salt provides a firm, level surface that is ideal for setting records. In 2014, world land speed record was set on the flats by British driver Andy Green, who reached a top speed of 763 mph.
Visitors can access the flats from Interstate 80 or State Route 30. There are several viewing areas along both highways where you can stop and admire the unique landscape.
