From the air, these turquoise colored salt evaporation pans provide a striking contrast to the surrounding desert. Bristol Lake, near Amboy and Cadiz Dunes in southeast California, has been a source of salts, both table salt (sodium chloride) and road salt (high in calcium chloride), for more than a century. Salt evaporation pans can serve either or both of two purposes: concentrating brine to recover salt or drying high-saline-content waste from desalination operations. The color of the evaporation pans comes from algae that live in the water; the algae’s colors reflect the nature and concentration of the salts.
