Timing of world land-speed record runs is under the jurisdiction of the United States Automobile Club. Not only does the high concentration of salt here make the terrain unique, but this is also the home of Utah’s famed measured mile and the site of world land-speed record runs. Named after an early military explorer, the flats are about 12 miles long and five miles wide. The flats were formed when ancient Lake Bonneville slowly evaporated and left behind a hard, white salt crust that can be up to five feet thick in the middle, tapering to about an inch on the edges. If you’ve never stopped for a closer look, take Exit 4 just before reaching the Nevada state line.

While driving on Interstate 80 in northwest Utah, you can’t help but notice the barren Bonneville Salt Flats.
