Located on Pigeon Creek in Washington County, the Dunkirk Mine was opened by the Dunkirk Gas Coal Co., who also owned the Acme Mine and coke works farther up the creek. In 1910 this coal mine was in a 78" thick section of Pittsburgh seam coal, and it was able to produce 1,500 tons per day. In 1921 the Dunkirk tipple burned. By then the operator was the Union Coal & Coke Company.
