Where is the visitor center?

The Borax Visitor Center, operated by U.S. Borax, a Rio Tinto business, is at 14486 Borax Road in Boron. Built in 1997, it tells the story of borax and the local community.
U.S. Borax’s Boron mine began as an underground mine in 1927 and became an open-pit mine in 1957. The mine itself is closed to the general public, so the visitor center is the place to learn about its history and see the operation from the public overlook.
