The Salt Flats in Utah Feel Like You’re on Another Planet
Utah is home to the Bonneville Salt Flats, one of the most surreal landscapes in America. It’s located in northwestern Utah, near the Nevada border, about 100 miles west of Salt Lake City. Here are some facts that are just as interesting as the flats themselves.
The Bonneville Salt Flats Are Remnants of an Ancient Lake
The flats are what’s left of Lake Bonneville, a massive prehistoric lake that dried up around 13,000-14,000 years ago. Covering 30,000 acres (46 square miles), the salt crust ranges from less than an inch thick at the edges to nearly five feet thick at the center.
It’s Home to World-Famous Land-Speed Records
The Bonneville Salt Flats are a hub for land-speed racing, but the highest recorded speed—631.4 mph by the Blue Flame in 1970—wasn’t set during Speed Week. Speed Week, held annually, draws racers to test their limits on specially prepared sections of the flats.
The Salt Crust Is 90% Sodium Chloride
The salt is nearly pure sodium chloride, the same substance as table salt. Scientists estimate 147 million tons of salt cover the flats, giving them their brilliant white glow that’s visible from miles away.
Photographers Love the Mirror Effect After Rain
During the wet season, a thin layer of water collects on the surface, creating a giant natural mirror. This stunning effect draws photographers and filmmakers from around the world. Movies like Independence Day have used the flats’ unique look for unforgettable scenes.
The Weather Swings From Extreme Heat to Freezing Cold
Summers can exceed 100°F, while winter nights drop below freezing. When wet, the salt crust softens, making parts of the flats dangerous to walk or drive on, so check conditions before visiting.
Microbes Thrive in the Salty Environment
Despite the harsh conditions, scientists have discovered extremophile microbes living in the salt flats. These hardy organisms survive in conditions similar to those on Mars, making the area a valuable site for research.
The Salt Flats Are Perfect for Stargazing
With no light pollution and a remote location, the Bonneville Salt Flats are a dream for stargazers. On clear nights, the reflective surface amplifies the beauty of the Milky Way and surrounding stars.
The Flats Are Shrinking Due to Human Activity
Salt mining and natural erosion are causing the Bonneville Salt Flats to shrink. Conservationists are working to protect the area, but the loss of salt is a growing concern for its long-term survival.
You Can Camp Nearby, But Not on the Flats
Camping isn’t allowed directly on the salt flats, but there are nearby options. Wendover, a town just minutes away, offers hotels, while dispersed camping is available on public lands in the surrounding area.
Visiting Is Free and Open Year-Round
You can visit the Bonneville Salt Flats without paying an entrance fee, except during special events like Speed Week. Whether visiting in the summer for the dry, cracked surface or winter for the reflective effect, it’s important to respect the area and leave no trace.
