On this special Christmas Eve episode of the American Shoreline Podcast, Peter A. Ravella and Tyler Buckingham take a trip up to the northern most reaches of the American Shoreline (not quite to the North Pole) with Craig Birrell, an adventurer, naturalist, outdoor educator, and all-around interesting guy to discuss his recent solo float trip down the Noatak River in the remote Brooks Range of Alaska. The river's entire course is north of the Arctic Circle.  The Noatak basin is the largest undisturbed watershed in the United States. The Noatak National Preserve alone encompasses 6,500,000 acres of public, protected land.
