Two straits can be observed in this image of the border between British Columbia, Canada, and Washington State, USA. To the north is the Strait of Georgia, between Vancouver Island (as well as its nearby Gulf Islands) and the mainland coast of British Columbia, Canada. It is approximately 240 km long and varies in width from 18.5 to 55 kilometres (11.5 to 34 mi).

Archipelagos and narrow channels mark each end of the Strait of Georgia, the Gulf Islands and San Juan Islands in the south, and the Discovery Islands in the north. The main channels to the south are Haro Strait and Rosario Strait, which connect the Strait of Georgia to the Strait of Juan de Fuca.

The Strait of Juan de Fuca, visible south of the large Vancouver Island, is a large body of water about 95 mi long forming the principal outlet for the Georgia Strait and Puget Sound, connecting both to the Pacific Ocean. It provides part of the international boundary between the United States and Canada.

Visible at the top edge are the snow-capped peaks of the Pacific Ranges, the southernmost subdivision of the Coast Mountains portion of the Pacific Cordillera. Located entirely within British Columbia, Canada, they run northwest from the lower stretches of the Fraser River to Bella Coola.

Canada - February 1st, 2011

This orthorectified image shows several lakes in the southern Coast Mountains of Canada. The one in the upper right corner is Harrison Lake, the largest lake in that mountain range, at about 250 square kilometres in area.

East of the lake are the Lillooet Ranges while to the west are the Douglas Ranges. The lake is the last of a series of large north-south glacial valleys tributary to the Fraser River along its north bank east of Vancouver, British Columbia. The river can be seen crossing the lower part of the image.

Two ranges belonging to the large Pacific Coast System are visible in northwestern North America: the Coast Mountains, upper left quadrant, and the Cascade Range, visible as a thin line of white peaks parallel to the green coastal plains.

The Cascade Range, part of the Pacific Ring of Fire, extends from southern British Columbia, Canada, through Washington state and Oregon to Northern California, USA.

It includes both non-volcanic mountains, such as the North Cascades in southern British Columbia and northern Washington, and the notable volcanoes known as the High Cascades in Washington, Oregon and northern California. Both of these divisions are visible here; the volcanic peaks of the High Cascades can be noted as a line of snow-capped summits.

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.
