Forty square miles of crystallized sodium chloride, remnant of ancient Lake Bonneville, stretch to the horizon in blinding white. This improbable surface has been the site of land speed records since 1914, when racers discovered that nothing else on Earth offers so much distance with so little friction. Hundreds of world records have been set here; cars have exceeded 600 mph; jet-powered vehicles have approached the sound barrier. The salt is free, the surface regenerates each winter, and the only limit is how fast humans can make machines go. The salt flats are both eternal and disappearing - mineral extraction is dissolving the surface that made the records possible.

When the climate changed 14,000 years ago, the lake evaporated, leaving mineral deposits across the basin. The densest concentration - the Bonneville Salt Flats - formed a surface harder and smoother than concrete....

Records fell continuously: 300 mph in 1935, 400 in 1964, 500 in 1965, 600 in 1965. Craig Breedlove's jet-powered Spirit of America set multiple records; Gary Gabelich's Blue Flame ...

Bonneville Salt Flats: The Fastest Place on Earth: The Threat

Photo credit Famartin, CC BY-SA 3.0. The salt flats are shrinking. Potash mining has altered the water flow that regenerates the surface; the salt layer that was once 5 feet thick has thinned to inches in places. Course lengths have been reduced as the usable area diminishes. Some years, monsoon rains leave the surf...
