Straits of Georgia and San Juan de Fuca, USA and Canada49.3N 123.8W
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.
