The text on the sign reads:

Piedmont Kilns

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 charcoal kilns in the region. The making of charcoal stopped in the early 1900s when the Union Pacific rail line was rerouted north of Piedmont, leaving Byrne with no economical means of transporting his product to market.

Kiln Design
Moses Byrne built the kilns out of local materials - sandstone and limestone. Each kiln has a large doorway and a high-placed, back side window for loading cordwood. Vent holes were designed around the bottom of each kiln so that charcoal makers could adjust airflow during use. Once workers filled a kiln with logs, large metal coverings were mortared into place over the doorway and window to seal it before firing.
