I believe we’re looking at—from foreground to background—South Pender Island (Pender Bluffs and the entrance to Bedwell Harbour), Saturna Island, Bellingham area in Washington State, and Mount Baker.
This uncropped photo was taken from Mount Tuam on Salt Spring Island with a telephoto lens.
Technical: Canon 1DX camera, 420 mm lens (300mm lens and 1.4 extension), 1/800 sec at f/8, ISO 200
