The Uinta County Sheriff's Office is looking for any information about vandalism done to the Piedmont kilns.

The office believes the damage to this Wyoming State Historical Site happened between July 1 and October 1.

Moses Byrne built the kilns in 1869 to supply charcoal for the iron smelting industry in Utah.

The conical limestone kilns measure 30 feet across and 30 feet high. Three and a half of the original four kilns remain. Most of the charcoal was sent to Utah on the Union Pacific Railroad, according to the Wyoming State Parks, Historic Sites & Trails Division.
