context_page_description: Canada has a vast geography that occupies much of the continent of North America, sharing land borders with the contiguous United States to the south and the U.S. state of Alaska to the northwest. Canada stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west; to the north lies the Arctic Ocean. Greenland is to the northeast and to the southeast Canada shares a maritime boundary with France's overseas collectivity of Saint Pierre and Miquelon, the last vestige of New France. By total area, Canada is the second-largest country in the world, after Russia. By land area alone, however, Canada ranks fourth, the difference being due to it having the world's largest proportion of fresh water lakes. Of Canada's thirteen provinces and territories, only two are landlocked while the other eleven all directly border one of three oceans.
  Canada is home to the world's northernmost settlement, Canadian Forces Station Alert, on the northern tip of Ellesmere Island—latitude 82.5°N—which lies 817 kilometres from the North Pole. Much of the Canadian Arctic is covered by ice and permafrost.
context_section_description: The Canadian Cordillera, contiguous with the American cordillera, is bounded by the Rocky Mountains to the east and the Pacific Ocean to the west.
  The Canadian Rockies are part of a major continental divide that extends north and south through western North America and western South America. The Columbia and the Fraser Rivers have their headwaters in the Canadian Rockies and are the second and third largest rivers respectively to drain to the west coast of North America.  To the west of their headwaters, across the Rocky Mountain Trench, is a second belt of mountains, the Columbia Mountains, comprising the Selkirk, Purcell, Monashee and Cariboo Mountains sub-ranges.
  Immediately west of the Columbia Mountains is a large and rugged Interior Plateau, encompassing the Chilcotin and Cariboo regions in central British Columbia (the Fraser Plateau), the Nechako Plateau further north, and also the Thompson Plateau in the south. The Peace River Valley in northeastern British Columbia is Canada's most northerly agricultural region, although it is part of the Prairies. The dry, temperate climate of the Okanagan Valley in south central British Columbia provides ideal conditions for fruit growing and a flourishing wine industry; the semi-arid belt of the Southern Interior also includes the Fraser Canyon, and Thompson, Nicola, Similkameen, Shuswap and Boundary regions and fruit-growing is common in these areas also, and also in the West Kootenay. Between the plateau and the coast is the province's largest mountain range, the Coast Mountains. The Coast Mountains contain some of the largest temperate-latitude icefields in the world.
  On the south coast of British Columbia, Vancouver Island is separated from the mainland by the continuous Juan de Fuca, Georgia, and Johnstone Straits. Those straits include a large number of islands, notably the Gulf Islands and Discovery Islands. North, near the Alaskan border, Haida Gwaii lies across Hecate Strait from the North Coast region and to its north, across Dixon Entrance from Southeast Alaska. Other than in the plateau regions of the Interior and its many river valleys, most of British Columbia is coniferous forest. The only temperate rain forests in Canada are found along the Pacific Coast in the Coast Mountains, on Vancouver Island, and on Haida Gwaii, and in the Cariboo Mountains on the eastern flank of the Plateau.
  The Western Cordillera continues northwards past the Liard River in northernmost British Columbia to include the Mackenzie and Selwyn Ranges which lie in the far western Northwest Territories and the eastern Yukon Territory. West of them is the large Yukon Plateau and, west of that, the Yukon Ranges and Saint Elias Mountains, which include Canada's and British Columbia's highest summits, Mount Saint Elias in the Kluane region and Mount Fairweather in the Tatshenshini-Alsek region. The headwaters of the Yukon River, the largest and longest of the rivers on the Pacific Slope, lie in northern British Columbia at Atlin and Teslin Lakes.
