Reduction in Size
Due to extraction of salt from the area, the salt flats have begun to disappear. Once around 90,000 acres in size, they are now only 30,000 acres. The salt layer is thought to be shrinking due to the use of the salt in the making of potash, a mineral ingredient used in fertilizer. A nearby potash plant uses a system of canals, pipes, and tunnels to collect the brine that is produced during the rainy winter season in the area. This brine is then used to make potash. The company has begun to voluntarily spray leftover brine back onto the salt flats. It is estimated that over 55 million short tons of salt have been taken from the salt flats since mining began in 1963. Geologists estimate that 18 inches of salt crust have been removed from the flats, and that the reduction of salt happens at a pace of one percent per year. In some areas, the salt is now a mere 1/2 inch thick.
