Potash Ponds
At the Moab mine, miners pump water from the Colorado River deep underground to reach the potash ore, which lies about 3,900 feet (1,200 meters) below the surface. The water dissolves the soluble potash into a brine, which is then pumped into underground caverns. Once it is fully dissolved, the potash brine is pumped to one of the evaporation ponds. The water in the evaporation ponds is dyed bright blue to help it absorb more sunlight and heat. This reduces the time it takes for the potash to crystallize, at which point in can be removed and processed for use as fertilizer. The ponds sit along Potash Road, which is a winding dirt road that is quite photogenic too. Note - the pair of ponds are fenced, for safety, so it could be tricky to find the best shooting angle unless yo have a drone. (Moab, Utah, USA)
