This area is a national treasure. Outside a few popular spots, most of Greater Yellowstone's wilderness sees little human activity in summer. In winter, the backcountry becomes an untracked paradise perfectly suited to ski touring. A visit at this time of year is a window to an older world. Bison stand motionless around steaming, thermal pools.

The Experience Win and Joe are setting off on this trip because they want to experience the essence of Greater Yellowstone in winter and test their own physical limits at the same time.
