The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
For example, snow cover and asphalt insulate the ground and homes can heat the ground (see also heat island). The line varies by latitude, it is deeper closer to the poles. The maximum frost depth observed in the contiguous United States ranges from 0 to 8 feet (2.4 m). [1] Below that depth, the temperature varies, but is always above 0 °C (32 ...

The Columbia Icefield is the largest ice field in North America's Rocky Mountains. [1] Located within the Canadian Rocky Mountains astride the Continental Divide along the border of British Columbia and Alberta, Canada, the ice field lies partly in the northwestern tip of Banff National Park and partly in the southern end of Jasper National Park.

Canada covers 9,984,670 km 2 (3,855,100 sq mi) and a panoply of various geoclimatic regions, of which there are seven main regions. [9] Canada also encompasses vast maritime terrain, with the world's longest coastline of 243,042 kilometres (151,019 mi). [20] The physical geography of Canada is widely varied.
The climatic snow line is the boundary between a snow-covered and snow-free surface. The actual snow line may adjust seasonally, and be either significantly higher in ...
The foundations underlying over-land segments is most often native soil or muskeg frozen to a given depth, and locally, bedrock. These surfaces may either be bare or are overlain, as is most commonly the case, with a snow cover. Over-ice segments of winter roads are often referred to as ice crossings, ice bridges or, simply, ice roads. [3]
