The Northern Rockies already looks like full on winter. With a mounting snowpack across Wyoming, Idaho, and Montana, resorts are optimistic for a good winter. Thanksgiving weekend marks the beginning of the season with Sun Valley and Big Sky opening first followed by Jackson Hole.

On Thanksgiving Day, Idaho's Sun Valley plans to launch its 77th winter season. Lifts on both Dollar and Bald Mountain are scheduled to operate for opening day. To get jazzed for the season, check out this winning time lapse video from Sun Valley's 2012 Gathering Festival of music and film. The video is called "A Taste of Time."

Montana's Big Sky also plans to open Thanksgiving Day. This winter, skiers and snowboarders will find new glades to ski on Lone Peak and Andesite Mountain. Thinning and tree removal for forest health have opened up more glades in the Bavarian Forest, Erika’s area, PK Ridge, Marshmallow Man, and Magic Meadows.

Wyoming's Jackson Hole Mountain Resort waits until the turkey dinner overeating settles before opening its lifts. Opening day is scheduled for this Saturday, Nov. 24, 2012. Lifts to be operating will be announced later in the week, with intermediates awaiting to inaugurate the new Casper lift.

In the meantime, Jackson Hole put together this review of last season to whet your appetite for this year:

All three resorts plan to operate daily once they open this week. Other destination resorts in the Northern Rockies will be opening in early December. To find information on snow conditions at resorts in the Northern Rockies, go here: Montana, Wyoming, and Idaho
