When the sun hits the Wasatch just so it’s a beautiful sight, a rich layer cake of color and texture and only one of the innumerable natural wonders of my home state.
This spectacle is the geological fingerprint of Lake Bonneville, a Pleistocene-era paleolake that used to cover most of Utah in its chilly depths. At its largest, about 15,000 years ago, Lake Bonneville was 1,000 feet deep and covered 20,000 square miles, making it easily the largest inland lake in North America at the time. As the geologic eras ambled by and the Bonneville Flood unleashed the ancient lake, draining it forever, it left sediment on more than the walls of the Wasatch. One gift that this sediment gave the world is an expanse of nothingness known as the Bonneville Salt Flats.
