Rio Grande spreader AX-41 plows snow on the main line at Crescent, Colorado, on March 21, 2003. It’s hard to tell that Crescent siding is on the right side of the plow! This major blizzard closed transportation through much of Colorado during the March 17-20 storm. Denver received 31.8 inches, while Coal Creek Canyon got 71.8 inches of heavy, wet stuff.
