Drive east from Bellingham on highway 542 (Mt. Baker Highway) until you reach the Mt. Baker ski area. The road loops around Picture Lake, you can't miss it... park alongside the road and walk a short distance along the lake shore to see this view.
Taken with a Canon 30D and Tamron SP24-135 lens at 24mm, 1/25 @ f/16.
Mt. Shuksan, in the North Cascades of Washington, is reflected in the still water of Picture Lake.
