History
U.S. Borax traces its roots to California's Death Valley, where borate deposits were discovered in 1872. The first 20 mule team hauled borax a sweeping 165 miles through Death Valley in 1883. Fully loaded with two ore wagons and a 1,200-gallon water wagon, the rig weighed 36.5 tons. Though the expansion of railways led to the 20 mule team's retirement, the team has lived on for more than a century as a trademark for U.S. Borax. The Borax Visitor Center tells this 150-year story of U.S. Borax in the local Boron community.
