Stop Stop!  "That looks like red salt!" said KUSM Director of Operations Gayle Ferrell, as Myron Marcotte, Mine Manager, drove the latest Myron Mobile through the underground cavern.  Sure enough, in salt mine terms, it was a mountain of red salt, piled by miners in the 50's and left behind as trash salt.  What is the red salt?  It is a combination of Halite (sodium chloride) Sylvite (potassium chloride) and other conglomerate minerals.   In past decades, miners either mined around red salt or discarded it because of its bitter flavor in cattle feed. Today, it is mined along with everything else to be used  for road salt.  The discovery of the red pile was lucky because as Gayle notes " You see a pile of rocks and it all looks gray and dirty until you get closer and remove the dust and then you find treasure!  As for the red pile: you can now find gorgeous chunks of red salt for sale at the Salt Cellar 650 feet underground.
