Lake Bonneville was a massive Ice Age lake that covered over 52,000 square kilometres of the American West until a catastrophic flood 14,500 years ago reshaped the entire region. The flood released over 4,000 cubic kilometres of water in just weeks, dropping the lake level by 100 metres almost overnight. Today, its remnants include the Great Salt Lake and the famous Bonneville Salt Flats, with ancient shoreline terraces still visible on Utah’s mountainsides. #geography #fyp #viral #usa #utah | U

And one of North America’s greatest lakes vanished. The Earth we live on… is nothing if not dramatic. | The Randall Carlson

The Bonneville Salt Flats have shrunk by 75% in the last 100 years, and they could vanish entirely by the end of the century, new research has found.⁠ ⁠ The flats — beloved by land speed racers, endurance runners, hobbyist rocket launchers and Instagram photographers — are losing about 1 square kilometer, or around 250 acres, per year, according to a study published this month in the journal Geomorphology. At that rate, the flats could completely disappear sometime between 2072 and 2126.⁠ ⁠ “The
