Roundhouse Crew Works in Snow slide
D&RGW engines 361 and 481 were trapped in a snow slide January 30, in Slate Cut, some six miles from Crested Butte, when they ran into a 1,000 foot slide from 10 to 20 foot deep. Stuck so tightly they couldn't back out, and the flanger between them was partly lifted off the rails. Crew from Gunnison roundhouse kept the engines alive for two nights until freed February 1st. This was during a record cold wave when the thermometer at nearby Taylor Dam went to 59 degrees below zero.
361 was damaged so badly in this incident that it never ran again.
