British Columbia, Canada; Washington, United States: N. Cascade Range/Canadian Coast Range. Mt. Baker is at lower left. Vancouver, on the Fraser River delta, and Bellingham, WA are barely visible. The Pacific tectonic plate is being driven under N. America, giving rise to the line of young volcanoes that includes Mts. Baker, Rainier, St. Helens, etc. The darker low country (right center) is the forearc basin lying inland (east) of the volcanic arc. Still farther east, the older Canadian Rockies are cloud-covered.
