According to geologists, the Redmond salt deposit is the remnant of an ancient inland sea, probably part of what they call the Sundance Sea, which places the deposit within the Jurassic Period. Over time, the salt that settled at the bottom of the sea was trapped within the earth and then pushed up near the surface close to the town of Redmond, Utah.
The deposit occurs with over 60+ natural trace minerals which gives the salt its unique color, unique flavor, and numerous health benefits. Because this deposit comes from an ancient sea bed, nature created the salt long before the earth experienced any pollution or contaminants that are troubling our oceans today.
The Redmond salt deposit begins about 30 feet below the surface, covered by a layer of bentonite clay, which has protected it from erosion and from the possibility of modern contamination.
