With the QUEEN CHARLOTTE ISLANDS, Vancouver Island forms part of a partially submerged chain of the Western Cordillera and is a continuation of the US coastal mountains. Its coastline is very rugged, especially on the west, where there are several fjordlike inlets - the longest being Alberni Inlet and Muchalat Inlet - that cut into a heavily forested, mountainous interior.
L'île de Vancouver, en Colombie-Britannique, est la plus grande île de la côte ouest de l'Amérique du Nord avec une superficie de 31 285 km2.
