Encircled with cables, the remains of what were once 16 charcoal kilns built in 1886 by Montanan Warren C. King bask in the sun at the Charcoal Kilns Historic Site on July 10, 2020, in Lemhi County, Idaho. Four kilns in various states of preservation can be viewed on a self-guided tour after a 5-mile drive on a gravel road. The brick kilns were used to turn timber into charcoal. The charcoal powered a smelter in Nicholia, across the Birch Creek Valley, to process lead and silver from the Viola Mine. The kilns are now part of the Caribou-Targhee National Forest.
