His tales of the pioneer life in Bankhead and the region remind folks of the town's great influence to the future social development of the national park, and the Bow Valley's once lucrative coal mining industry. Submitted by Johnnie Bachusky, a Bow Valley writer and ghost town enthusiast. Coal was the reason for Bankheadâs birth, and the poor quality of that product the reason for its demise. The Canadian and Pacific Raiload founded the town in 1903. It had police barracks, churches, saloons and even a Chinatown. It flourished until 1921. As the mining families moved away, Bankhead became a ghost town with its 44 homes, recreational hall and other buildings standing empty.
