Over the past 20 years I've written about adventure, the environment and the remote corners of the world for a variety of national and international magazines, ranging from National Geographic and National Geographic Adventure to the New York Times, Atlantic Monthly and more. A six-time grantee of the National Geographic Expeditions Council, those adventures have led my teams and me to each continent, and have included riding a cargo boat through the South Pacific, two-man sledding to the heart of Antarctica, sea kayaking along its coastline and first descents of rivers in Chile and China. Along the way I've written ten books and produced a dozen documentary films.
