Bonneville Salt Flats

The salt flats are the dried-up bed of an ancient lake. During the Ice Age, a huge body of water called Lake Bonneville covered much of western Utah, far larger and deeper than the Great Salt Lake that survives as its remnant. As the climate warmed and the lake shrank and evaporated, it left its dissolved minerals behind on the basin floor.

What remains is a crust of salt, mostly common table salt, laid down in a layer that in places is many feet thick and packed hard and smooth. Each winter, water pools on the flats and dissolves the surface, then evaporates in the dry summer to redeposit it, a yearly cycle of flooding and drying that keeps the plain so remarkably level and white.

The flats' extraordinary flatness and length made them the natural stage for the pursuit of pure speed. Beginning in the early twentieth century, racers laid out a course on the salt, and the Bonneville Speedway became the place where many of the world's land-speed records were set, drivers pushing streamlined cars and jet-powered machines to astonishing velocities across the white.

The tradition continues in the events known collectively as Speed Week and beyond, when enthusiasts bring homemade and factory machines of every description to see how fast they can go. The very idea of Bonneville, the long shot at a record on a plain of salt, has become part of American automotive lore, drawing pilgrims to a place that is empty most of the year.

The flats are transformed by water. When a shallow layer of rain or runoff spreads across the salt without any wind to ripple it, the plain becomes a perfect mirror, reflecting the sky, clouds, and distant mountains so completely that the horizon dissolves and photographs look like the subject is standing on the surface of the sky.

This mirror effect, along with the blinding white by day and the vivid colors of sunrise and sunset, has made the flats a magnet for photographers and filmmakers. The same water, though, is a warning: when the salt is wet it will not bear a vehicle, and countless cars have sunk to their axles by driving out onto a surface that only looked solid.

For all their toughness, the salt flats are a fragile resource. The crust has thinned over the decades, and there is ongoing work to restore salt to the flats to keep the racing surface and the landscape intact. Visitors help by staying off the salt when it is wet and treating the surface with care.

This is genuinely remote country, hot and shadeless in summer, with no water or services on the flats themselves and the small border town of Wendover as the nearest base. Coming prepared with water, sun protection, and a full tank is essential. In return, the flats offer an experience of scale and emptiness found in few other places, a horizon of pure white under an enormous sky.

The Bonneville Salt Flats are a vast, otherworldly expanse of hard white salt crust in western Utah near Wendover, a remnant of the ancient Lake Bonneville that once covered much of the region. Stretching flat to the horizon, they are famous worldwide for land-speed racing and for their surreal, mirror-like beauty. Free to visit, the flats offer a landscape unlike anywhere else, whether cracked into geometric salt patterns when dry or reflecting the sky like glass when wet.

Sometimes, but only when the salt is dry and stable and only in the designated areas. Driving on wet salt damages both the flats and your vehicle and can get you stuck, so avoid it entirely when the surface is damp. When conditions allow, start slowly, since the salt drives unlike any normal road, and steer clear of any spots that feel soft. Afterward, rinse your car thoroughly, since the salt is highly corrosive to vehicles.

For walking or driving on the flats, the dry season, roughly summer into early fall, is best, when the salt is firm. The wetter months create a stunning mirror-like surface that is beautiful for photography but not for driving. The famous land-speed racing events, including Speed Week in August, are a spectacular time to visit, weather permitting. Sunrise and sunset are magical and cooler, so many visitors time their trip for the soft light.

Come prepared, since there are no services, shops, shade, or shelter on the flats. Bring plenty of water, snacks, sunscreen, and a full tank of fuel, and make sure your car is in good shape, since there is no help nearby. The open terrain is prone to strong wind gusts and intense sun and heat, so dress accordingly. Sunglasses help against the blinding white glare, and a hat and sun protection are essential year-round.

The flats lie near Wendover on the Utah-Nevada border, about ninety minutes west of Salt Lake City along Interstate 80, with Wendover offering the nearest services, fuel, and lodging. The nearby Tree of Utah sculpture along the highway is a quirky roadside stop. Because the drive crosses a lot of empty desert, the salt flats are usually visited as a dedicated trip or a memorable break on a cross-state journey along I-80.
