What is the significance of the Rocky Mountains?

The Rocky Mountains form the western spine of Canada, running roughly 1,500 kilometres from the United States border northward through Alberta and British Columbia. The Canadian Rockies include four contiguous national parks (Banff, Jasper, Yoho, Kootenay) and three provincial parks (Mount Robson, Mount Assiniboine, Hamber), together designated the Canadian Rocky Mountain Parks World Heritage Site by UNESCO in 1984. Mount Robson, at 3,954 metres, is the tallest peak in the Canadian Rockies.

The mountains have shaped Canadian transportation, settlement, and tourism. The Canadian Pacific Railway crossed the Rockies through Kicking Horse Pass and Rogers Pass to complete Confederation's promise of a transcontinental link in 1885. The Canadian Northern Railway followed through Yellowhead Pass in 1915. The Trans-Canada Highway, completed in 1962, parallels the CPR through Banff and Yoho. Lake Louise, Moraine Lake, the Columbia Icefield, and the Athabasca Glacier draw millions of visitors a year.

The Rockies are the source of three of Canada's largest river systems: the North and South Saskatchewan rivers (which flow into Hudson Bay), the Athabasca and Peace rivers (which flow into the Arctic Ocean via the Mackenzie), and the Columbia (which flows to the Pacific). Glaciers feeding these systems have receded significantly since 1880, and Parks Canada now monitors the Athabasca and Saskatchewan Glaciers as climate-change indicators.

Indigenous peoples have lived in the Rockies for at least 11,000 years. The Stoney Nakoda, Ktunaxa, Tsuut'ina, and Cree nations have known and used the mountains across generations, with sites such as Banff's Cave and Basin recognised in modern co-management agreements between Indigenous nations and Parks Canada.
