The Harmony Borax Works are located in Death Valley at Furnace Creek Springs, then called Greenland. They are now within Death Valley National Park in Inyo County, California. It is on the National Register of Historic Places.
After discovery of Borax deposits here by Aaron and Rosie Winters in 1881, business associates William Tell Coleman and Francis Marion Smith subsequently obtained claims to these deposits, subsequently opening the way for "large-scale" borax mining in Death Valley. The Harmony operation became famous through the use, from 1883 to 1889, of large Twenty-mule teams and double wagons which hauled borax the long overland route to the closest railroad in Mojave, Califor@r />
During the summer months, when it was too hot to crystallize borax in Death Valley, a smaller borax mining operation shifted to his Amargosa Borax Plant in Amargosa, near the present community of Tecopa, California. The Harmony Works remained under Coleman's operation until 1888, when his business collapsed.
