This episode is a color remake of the series pilot, "She Burns Green" which aired as the second episode of the first season.
In 1881, Aaron and Rosie Winters discovered a large bed of borax in Death Valley. They sold their claim to a borax mining company for $20,000 (about $460,000 in 2018). They bought a ranch in Pahrump, Nevada (about 60 miles from present-day Las Vegas). Rosie died a few years later, and Aaron lost most of the ranch to back taxes in 1887.
