When the snow falls, where are your favorite stashes? Maybe your list includes Mott or Killebrew Canyon at Heavenly, Monument Glade at Northstar-at-Tahoe, Whale’s Tail at Breckenridge, Royal Elk Glade at Beaver Creek, the Windows at Keystone, or Blue Sky Basin and the Back Bowls at Vail. Those are all relatively easy to reach—a few chairs lifts and some traverses and you’re there—but how about a spot that’s a little more exclusive? Sure, those favorite easier-to-access trails are going to be in pristine condition, but my legs are all in favor of another not-so-secret stash: a trip to the backcountry with Keystone Adventure Tours.
