Boron 20 Mule Team Days


Celebrating nearly 150 years of innovation

History of the U.S. Borax
20 Mule Team

The first Borax 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.
 

20 Mule Team Borax—TV Show

The 20 Mule Team® Borax brand originally became a household name through the radio program Death Valley Days which evolved into a TV show (now available on DVD) starring Ronald Reagan. The teams rode for:

  • 1904 St. Louis World’s Fair
  • President Woodrow Wilson’s 1917 inauguration
  • The dedication of the San Francisco Bay Bridge in 1937
  • 1999 Rose Parade

145-Year History as a Leading Supplier of Boron

In celebration of this historic icon’s 145th anniversary, a full-scale, authentic, working replica of the wagons rode in the 2017 Rose Parade. Construction of the replica wagons took nearly two years, to ensure their authenticity and capability.

Since the discovery of borates in California’s Death Valley in 1881, Borax has come a long way. Over our 145-year history as a leading supplier of boron, many things have changed. Today, the boron we mine is used in everything from soap (sold today through partnership with Henkel Dial) to fertilizers to cell-phone glass.

But one thing never changes: our innovative spirit and commitment to our customers, employees, and community.

Death Valley National Park

Stephen T. Mather created the 20 Mule Team brand when he launched his career at the Pacific Coast Borax Company, which became U.S. Borax before being acquired by Rio Tinto in 1967. It was the start of a lucrative business venture, and one that would lead him from mining to his ultimate calling—helping to create the National Park Service.
