If I were you, I would skip Telluride, because just getting there and out will take lots of time away. I would go over to Montrose, to Ridgeway, Ouray, Silverton, then Durango. You can spend a night or two in any of those citys, however, I feel Ouray and Silverton are the best. Do CO, and then go down to NM. If you want to stay north, you can go to the Aztec Ruins near Farmington, but if you really want Cliff Dwellings, you want to go south near Silver City and do the Gila Cliff Dwellings.
