I've been fortunate to hear from better informed experts on Seattle's past topology as I've posted these photo mash-ups over the last few years. That first batch especially had a few mistakes. Sometimes the image alignments were a little off -- Sometimes a lot. David B. Williams was nice enough to point out that the 1914 photo of the McNaught house was actually situated on the southeast corner of 6th and Marion, not the northeast as shown in my original composite. So, here's a do-over with the house where it should be. If anything, the elevation difference looks even more dramatic now. Thanks, David!
