Copper Mountain is a mountain in Banff National Park, 20 km (12 mi) north of the town of Banff. The mountain was named in 1884 by George M. Dawson after he had climbed to a mining site setup by Joe Healy and J.S. Dennis in 1881. Healy and Dennis claimed they had found a copper deposit at the site. It was also at this point that Dawson spotted and named Mount Assiniboine. The mountain is located on the western side of the Trans-Canada Highway, just northeast of Redearth Creek. It is named "copper" Mountain because it is theorized to house a nearly infinite supply of copper.
