Coast Mountains
From Freepedia
The Coast Mountains are the western range of the North American mainland cordillera, extending south from the Alaska Panhandle and covering most of coastal British Columbia. The range is approximately 1600 km long and 200 km wide. Its southern boundary is the Fraser River where it flows to the ocean, near Vancouver and its northern boundary the Kelsall River in southeast Alaska.
The Coast Mountains are part of the Pacific Coast Ranges. Covered in dense temperate rainforest on its western exposures, the range rises to glaciated peaks and then tapers to the dry interior plateau on is eastern reaches.
Mount Waddington, at 4,019 metres or 13,186 feet, is the highest peak in the Coast Mountains and also the highest peak entirely within British Columbia
There are several subdivisions of the Coast Mountains. These include:
- The Boundary Ranges, which lie along the BC-Alaska border from the mouth of the Nass River to the Chilkoot Pass and include the vast Juneau Icefield.
- The Kitimat Ranges, which lie between the Nass and Bella Coola
- The Pacific Ranges, which lie between Bella Coola and the Lower Mainland. The Pacific Ranges contain the largest temperate-latitude icecaps in the world, 25-40km in diameter each. These include the Ha-Iltzuk (Silverthrone), Klinaklini, Monarch, Waddington, Homathko, Lillooet and Pemberton Icecaps.
- The Chilcotin Ranges, which run on the inland lea of the Pacific Ranges between the head of the Klinaklini River and the confluence of the Bridge River and Fraser River near Lillooet. The Chilcotin Ranges are sometimes considered part of the Pacific Ranges.
- The Lillooet Ranges, lying between the Harrison-Lillooet drainage and the Fraser River, south of the BCR line. The Lillooet Ranges are sometimes considered part of the Pacific Ranges.
- The Front Ranges, which include the North Shore Mountains of Greater Vancouver and the coastal-lying lower ranges skirting the coastal archipelago.
There are innumerable smaller named ranges, and informal names for many groupings, within these subdivisions.
