After leaving Eagle, mushers travel northwest for on the Yukon River, except for a few short portages. During this stretch, two hospitality stops are available. The first is from Eagle at Trout Creek. The next is Biederman's Cabin, the former home of Charlie Biederman, one of the last people to deliver mail by sled dog. (The final sled dog mail route was canceled in 1963, and Biederman's sled hangs in the National Postal Museum.) A dog drop site is located from Biederman's Cabin at Slaven's Cabin, a historic site operated by the National Park Service. Some past Slaven's Cabin mushers arrive in Circle, so named because its founders believed it was on the Arctic Circle. (Circle is actually about south of that line.)
