From October 2011 to January 2012, Will Stauffer-Norris and his buddy Zak Podmore hiked and paddled from Wyoming's Wind River Mountains to Mexico following the Colorado River system from its farthest inland source to the sea. Now he and and Zak have embarked on a new Colorado source-to-sea expedition, this time starting from Rocky Mountain National Park. Will's address is constantly in flux, but he resides mainly in Colorado. www.downthecolorado.org
