Colorado was walloped by a monster blizzard, with huge snow flakes and sub-freezing temperatures. The weather caused rocks to break loose and fall on the tracks, which held up the Zephyr until the rocks were moved and the track was cleared. AMTK 33 then lead the Zephyr through the sweeping turn at Crescent, Colorado during the height of the snowfall.
Two Amtrak routes serve the Centennial State. The California Zephyr's route through Moffat Tunnel and along the Colorado River goes from one end of the state to the other. The Southwest Chief cuts across the southeast corner.
