A strong upper level jetstream coupled with a very deep fetch of Pacific moisture, produced a prolonged period of heavy snow and strong winds in the mountains.  Peak wind gusts above timberline ranged from 55 to 65 mph.  The winter storm made travel nearly impossible at times, including Interstate 70 between Georgetown and Vail Pass.  In the mountains, storm totals ranged from 2 to  4 1/2 feet.  A SNOTEL site near Rabbit Ears Pass measured 54.5 inches of snow.
