This nearly east-west line of volcanoes stretches from the west coast of B.C., just north of Vancouver island, and reaches into the Interior Plateau near Quesnel. The volcanoes generally get younger as you go from the coast to the interior. These volcanoes probably formed as a result of the North American continent sliding westward over a small "hotspot", like the one feeding the Hawaiian islands. Volcanoes in this belt include the Rainbow, Ilgachuz, and Itcha ranges, and the Nazko cone which is only 7200 years old.
