Coast Mountains, Canada and USA - June 2nd, 2009

The Coast Mountains are a major mountain range of western North America, so-named because of their proximity to the sea coast.

The ranges extends from southwestern Yukon Territory in Canada, through the Alaska Panhandle in the USA and stretches along virtually all of the coast of British Columbia in Canada.

The section visible here is mostly in the province of British Columbia, although the coastal area on the left side is part of Alaska.

The Coast Mountains are approximately 1,600 kilometres (990 mi) long and average 300 kilometres (190 mi) in width. The range is part of the Pacific Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean.

However, the range includes volcanic and non-volcanic mountains, the huge icefields of the Pacific and Boundary Ranges, and the northern end of the notable volcanic system known as the Cascade Volcanoes.

Covered in dense temperate rainforest on its western exposures, visible here as a green band between the snow-capped peaks and the blue waters of the Pacific Ocean, the range rises to heavily glaciated peaks, including the largest temperate-latitude icefields in the world.

The mountains then taper to the dry Interior Plateau on its eastern flanks, or to the subarctic boreal forest of the Skeena Mountains and Stikine Plateau.
