Glacier NP (BC) is one of my favourites but it is not in the Canadian Rockies but rather in the Selkirks which are part of the Columbia Range. These have very different rock formation (volcanic) than the Rockies and are separated by the wide Columbia Valley.

"Canadian Rockies, segment of the Rocky Mountains, extending southeastward for about 1,000 miles (1,600 km) from northern British Columbia, Canada, and forming nearly half the 900-mile (1,500-km) border between the provinces of British Columbia and Alberta. The Mackenzie and Selwyn mountains farther north along the border between the Northwest and Yukon territories are often included in the Canadian Rockies. To the west, the Rocky Mountain Trench (a geologic depression) separates the front ranges of the Canadian Rockies from the Columbia Mountains, which include the Cariboo, Selkirk, Monashee, and Purcell mountains and are also often considered part of the Rocky Mountain system."
Got that info from Wikepidia. You will have to look it up but it says that the Columbia Mountains which are made up of the Selkirks, Purcells, Monashees and Caribou Mts. and are geologically distinctly different from the nearby Rockies and are separated by the Columbia Valley. It also says that Glacier NP is made up of the northern Selkirks. Them English types from Encyclopedia Britanica don't know anything about their former colonies.
