One of the premier ski resort towns is Jackson Hole. With its ski-in/ski-out property, luxurious accommodations and backcountry access. But the back country access wasn't always there. There was a time when the ski patrol at Jackson Hole had run-ins with an underground group.

The Jackson Hole Air Force was a group of renegades, skiing in areas forbidden by the ski resort and by the U.S. Forest Service. They gained a great deal of notoriety with their antics and their wars with the ski patrol. However, when Jackson Hole ski resort was opened to back country access, the group faded away.

An award-winning documentary, Swift. Silent. Deep. revisits the Jackson Hole Air Force and puts things into perspective. You can also read a profile on the group from The Ski Channel.
