Potash Evaporation Ponds Moab, UT

Shown in this picture are a series of evaporation ponds for potash, or salts that contain potassium used for fertilizer located near Moab, UT. A solution is pumped into the ground at the potash mine (not pictured) 2,400 to 4,000 feet underground to dissolve the potash. The solution is then pumped to the evaporation pools, dyed blue to increase evaporation and left to dry in the sun for ~300 days before it is scraped up and shipped off for further processing. The varying coloration in the ponds is due to the difference in water concentration in each pond. This picture was not cited except to credit NASA however similar pictures, with the same angle and resolution, of this mine are attributed to Landsat 8.
