I must say thanks for all the input, but unless the depot was further out of town on the route to the northwest of town headed to Grand Junction I don't recognize the landscape at all. The original line to Montrose is on the west side of town - of course the Summerset branch, to the coal mines to the east, is on the N end of town. they sort of form a Y if you will, where the 2 branches merge. The puzzle are those barren hills behind the depot. There are some small hills like the first
level but flatten out behind - they don't continue to climb as these look????
this AM I found these but am wondering the cira 1921 looks like Montrose version & the 1910 version looks like Ridgeway or Doloris depots which I guess that could be true with changing times??
