Brothers John and Eric Jackson set up with Travis Rice and Ian Walsh for one of their final days in the Alaska backcountry before embarking south to continue their search of powder stashes throughout Canada, the United States and South America. John stays on the sidelines for most of the day due to a back injury, but eventually gets in a couple laps and a gnarly tomahawk to end the day. Also check out the first and second episodes of Brothers on the Run.
