An early autumn snowfall in the higher elevations of Mullan Pass frames Austin Creek Trestle at Skyline, Montana, on October 11, 1997. Lower elevations toward Helena received rain, but a frosting of snow sticks to the trees up on the pass, creating an unusual look to the scenery. A westbound Burlington Northern Santa Fe train is grinding up the grade with an A-B-A set of former BN power; SD40-2s Nos. 7070 and 7028 sandwiching GE B30-7AB No. 4107.
