I've heard Rock Creek area of Montana as well. The officer in the first pic is definitely a Montana officer. I saw an absolute giant of a ram standing on the shoulder of the road in that area last winter.
It looks like the rock creek area...the warden is definately Dan Curtin. I've known Dan about as long as he's been a warden. He checked my buddies and I all the time when we were hunting ducks and geese near Missoula.
