The Bonneville Salt Flats in western Utah are one of the most surreal landscapes in the United States a vast, blindingly white expanse of salt that transforms into a glowing blue mirror under the right conditions. After rainfall or during the wet season, shallow water covers the flats, perfectly reflecting the deep blue sky and creating an infinite horizon that blurs the line between earth and heaven.
Why Do the Bonneville Salt Flats Turn Blue?
The iconic “blue” appearance isn’t from colored salt it’s pure white sodium chloride but from perfect sky reflections on a thin layer of standing water:
- The flats are the dried bed of ancient Lake Bonneville, covering about 30,000 acres with a hard, flat salt crust up to 5 feet thick.
- Rain or winter moisture creates a flawless mirror surface, turning the white ground into a brilliant blue expanse under clear skies.
- At sunrise or sunset, hues shift to pinks, oranges, and deeper blues for even more dramatic effects.
This optical illusion makes it one of the most photographed natural wonders in Utah, often compared to Bolivia’s Salar de Uyuni.

- Records include over 600 mph in jet-powered cars the ultimate test of speed on natural terrain.
