You can't miss the Calumet sign downtown.  The train station is still there.  The gas station looks a little different.  Drive -in should be there still.

The area they filmed in the mountains burned earlier this year,iirc.  Hermit's Peak is where they filmed..

Only thing I never found was the Teddy Roosenfelt statue.

Check out the Rough Rider museum.

Not sure of the name.  You will see it heading north out of town, not too far from the drive -in.

What are you up to out here? Lots of good food around Santa Fe. As others have said many areas closed or burned up by the recent fire near Las Vegas, but as I understand it there were many scenes filmed near Hermits peak and up near Abiquiu. I'm in Los Alamos, if you strikeout due to the fire closures there is a cool museum and sights from the original lab up here. Also a cool museum at Kirtland if you're into that sort of thing. If you end up by Chimayo there is an excellent restaurant there (linked below).
