Is that the case for Maybell to your west? If I'm not mistaken, I believe they hold the all-time record low for the state of -64F (or in that neighborhood -- I did a social studies fair project on Colorado back in elementary). I always thought it was odd that a low elevation would hold the record low but it makes sense as the cold air really can pool in some of the valleys (I often notice this occurring in the San Luis Valley while it is actually warmer in Wolf Creek Pass or the Sangre De Christos than it is in Alamosa.
Yes, same for Maybell. Maybell is just to the west of us and only 5920 feet elevation. The official record low there was -61F.
It's amazing how much a difference a few hundred feet elevation change can make.
Maybell has been officially down to -61F and verified temperatures in Craig down to -56F. Some people have recorded (unofficial) temperatures of -64F down by the river. The Trapper Mine, which sits at 6440 feet and where the Craig SW station is located has only been down to -41F. Still chilly, but much warmer considering it's only a few hundred feet higher and only a few miles away. The valley floors get much colder at night than the hills do, at least on clear nights.
