The Piedmont Charcoal Kilns southwest of Evanston, Wyo. were built in 1869 to supply charcoal primarily to Utah mining and smelting operations. The town of Piedmont’s location—on the Union Pacific Railroad but near a ready timber supply in the Uinta Mountains—made it a logical spot for the industry. Most of the charcoal was shipped to the Salt Lake valley, and some to Fort Bridger for use in blacksmith forges and heating stoves. Piedmont was a railroad station on the Union Pacific line. Three of the original five kilns remain standing. The site is on the National Register of Historic Places.

The JC Penney Company, long among the world’s largest department store chains, traces its roots to a one-room shop in a small Wyoming coal-mining town at the turn of the last century. Penney’s career in Wyoming lasted just a decade, but in 1902, Wyoming provided exactly what young Penney needed to found a chain that has survived, as of 2011, for 109 years.
