Mine: Elkhorn Mine
Description: A peculiar feature of the reduction plant at Elkhorn is shown here. The tailings are impounded by a series of dams built up of sacks filled with tailing sand. The bags are those in which the salt used by the mills is received. Their cost is therefore trifling, and when filled with sand they form excellent retaining walls. These dams are made necessary by the fact that the water is used by the ranchmen downstream for irrigation.
