Aniuk River Points
You should be able to arrange a pickup here and then fly out of Kotzebue.
Howard Pass is accessible by wheelplane from Bettles, Coldfoot, or Kotzebue. You will have to carry your gear at first to the small rocky stream that is the Aniuk River and for many miles the river is small and you may have to line through some of the sharp rocky riffles.
For anyone not interested in the beautiful headwaters and instead wants the wide valley of the lower river then there is a gravel strip at the confluence with the Cutler River where you could start.
For those interested in seeing some of the upper Noatak you can continue 20 miles more to fly out of the gravel strip at the confluence of the Cutler River and the Noatak River.
