The panorama above shows a view of the Bonneville Salt Flats and surrounding mountain ranges in northwestern Utah. Steady winds have ruffled Bonneville’s surface forming the conspicuous windrow. A combination of wind and water created these salt flats. When rain falls here, during the cold season, it accumulates in a very thin layer since the surface is so level it has nowhere to drain. As the weather warms, the shallow “lake” water slowly evaporates, adding a new layer of salt, chiefly potassium, magnesium or sodium chloride. Note that it's likely that the "new salt" is really a combination of old, recrystallized salt, as well as some new additional salts that drain into the lake from the surrounding hills. Panorama taken on July 10, 2010.
