Has any one taken a surface drive up the Sheenjack or the Coleen rivers. If so or if you just have any experience with these rivers how far do you think one could get.
Had a friend go to the Sheenjack a few years ago. He launched his boat in Circle and went up the mouth of the Sheenjack a few miles. He hired a piolt out of Ft. Yukon to fly him and his partners up to the headwaters and it took them 23 days to float down to the boat. This was the first of August and he said they encountered cold nights and ice.
