The top photo is of the real Dawson City, Yukon. The bottom photo is a fake Dawson City; it is actually a movie set in Haines, Alaska leftover from the making of the movie White Fang.
It is easy to see why Hollywood would go to the efforts to build an entire city not too far from the real one – the Hollywood version is so much easier to photograph, there aren’t cars, people, powerpoles, powerlines and a bunch of other visual distractions. I thought it was interesting to see how much smaller the building were in the Hollywood version. I didn’t realize this at the time, but it became more obvious after looking at my photos of both locations side by side.
