Old Harmony Borax Works
On the marsh near this point borax was discovered in 1881 by Aaron Winters who later sold his holdings to W.T. Coleman of San Francisco. In 1882 Coleman built the Harmony Borax Works and commissioned his superintendent J.W.S. Perry to design wagons and locate a suitable route to Mojave. The work of gathering the ore (called cottonball) was done by Chinese workmen. From this point processed borax was transported 165 miles by twenty mule team to the railroad until 1889.
