Desert riches

Since ancient times, borax and other borate minerals have been used in the Near East and Asia as an antiseptic, a washing agent, and welding flux. Europeans were not introduced to borates until the 13th century, when Marco Polo returned from Asia with borax crystals. However, borax remained a rare commodity until rich lakebed deposits were found in California and Nevada in the 1850's and 60's.

By the 1870's, an expanding market for borax motivated miners to search for new deposits in the desert playas of California and Nevada. In 1881, Rosie and Aaron Winters discovered borax on the Death Valley playa at the mouth of Furnace Creek wash in Death Valley.

Borax mining in Death Valley

Death Valley's first commercial borax operation began in 1881 at the Eagle Borax Works. W. T. Coleman's Harmony Borax Works followed in 1882 and the town of Greenland was built. This early outpost was later to become the modern Furnace Creek Ranch. Harmony played a central role in the opening of Death Valley and the subsequent popularity of the Furnace Creek area.

Ore production began in late 1883 or early 1884. When in full operation, the Harmony Borax Works employed forty men. These hardy workers scraped cottonball borax from the surface of the playa, producing three tons of borax daily.
