I have studied overhead and satellite imagery of this area to know precisely where that photo was taken from the aircraft. I did not know precisely where it was when I first saw it but my first guess was 100% accurate. That was the first place I looked for on the image of Google maps. The river seems obvious but it is not obvious from that photo. Only after finding it on the map does it become obvious that it is a river. Also, there are a lot of miles of river coastline in the Seattle area but I zoomed in precisely on that location when I first started to examine the maps. The others in that set of images are a lot easier to find on the map.
