Potash Ponds — These electric blue molds in the brown desert are potash fumes from ponds operated by Intrepid Potash, Inc., the largest producer of potassium chloride in the United States. These ponds are located along the course of the Colorado River, about 30 kilometers west of Moab (Utah, USA). These ponds have an area of 1.5 square kilometers and are lined with rubber to retain the salt.
