In 1887, the First Nations of the area signed Treaty 7, which gave Canada rights to explore the land for resources. At the beginning of the 20th century, coal was mined near Lake Minnewanka in Banff. For a brief period, a mine operated at Anthracite but was shut down in 1904. The Bankhead mine, at Cascade Mountain, was operated by the Canadian Pacific Railway from 1903 to 1922. In 1926, the town was dismantled, with many buildings moved to the town of Banff and elsewhere.
