Borax Mining

An open pit borax mine.  Borax is a compound containing the element boron.  This mine supplies about half of the world's boron.

A 20 mule team borax train.  The rear wagon contains water for men and animals.  Usually the first two animals are horses; there are actually 18 mules.   I haven't yet found out what the barrels on the sides of the borax wagons are for.

This mine truck is 30 years old and small by todays standards.   It's now parked in a park in Boron.

This tire from a mine truck must be at least 10 feet in diameter.
