The Canadian Rockies

The Canadian Rockies comprise the Canadian segment of the North American Rocky Mountains range. The southern end in Alberta and British Columbia borders Idaho and Montana of the USA. The northern end is at the Liard Plain in British Columbia.

Contrary to popular misconception, the Rockies do not extend into the Yukon or Alaska, or into central British Columbia. North of the Liard River, the Mackenzie Mountains, which are not part of the Rockies, form a portion of the border between the Yukon and the Northwest Territories. The mountain ranges to the west of the Rocky Mountain Trench in southern British Columbia are called the Columbia Mountains and are not considered to be part of the Rockies.
