Over perhaps a dozen trips to Telluride in the winter, I believe I've only been diverted on the inbound once. Well twice now! Came in from Phoenix on a Dash-8, practically a jumbo next to the Beech 1900s. Below minimums, we diverted to Montrose. Picked up 5000 pounds of Jet-A; and 22 passengers got off while 3 of us stayed on. Gabriel said the weather was looking OK, and sure enough, we shot the approach at 2000 ft ceiling and 2 mi visibility.
