Took a short flight north from Fairbanks across the Arctic Circle and landed at Coldfoot - gateway to the NPS Gates to the Arctic National Park. Five of us from the Airstream caravan exchanged one thin aluminum tube for another faster but smaller diameter aluminum tube! Below us the Alaska pipeline and Dawson Highway head off to Prudhoe Bay some 400 miles further north on the arctic ocean.... Our plane officially crosses the Arctic Circle...at N66:33:00- W149:40:99.... At this point in its flow to the Bering Sea, the Yukon river meanders across the plain with many ox-bow lakes and islands....
