I don't know if southwest Colorado counts or not, but we're modelling the Silverton RR, based in the San Juan Mountains.
Musket Miniatures has some period figures, and lots of animals, you might look at their online catalog.
I got a whole bagfull of cowboys and Indians from a friend who does military dioramas. I think they're 1:72 scale, but they are less than half a head taller than 1:82 scale figures I have, so with some care, you should be able to place them so as to avoid having them look like mismatched giants. Look in the military figures section at your LHS, get brandnames off the packages, then look at their larger catalogs onine to find the less popular figures.
Pictures hmmm?
I have a mule train and driver for this, but they're off layout while some remodelling takes place.
This is a staged photo...no ballast yet, the water tower isn't painted, (or even glued together, I just bought it for the spount, plan to scratchbuild my own tank).
Just some Old Time motive power eyecandy here, enjoy!
