With vast timber stands in the nearby Uinta Mountains, Moses Byrne saw an opportunity, and in 1869 he built kilns to supply charcoal for the iron smelting industry in Utah. The conical-shaped kilns measured 30 feet across and 30 feet high. These kilns are one of the best remaining. intact set of kilns in the region. In early 1900 the making of charcoal stopped when the Union Pacific rail line was rerouted north of Piedmont, leaving no means of transporting the charcoal to market.
