In June Roman Dial, Derek Collins and I started just south of Cantwel and hiked up the the West Fork of the Chilitna River. We did a short side trip that afternoon and floated the gorge (Class 3+). The next day we crossed over to the head of Tsusena Creek. We portage one waterfall and floated the rest (Class III/IV) down to the Susitna. We took out a few miles down the Susitna and hike up to Stephan Lake. Across Stephan Lake, down Prairie Creek to the Talkeetna. After only a couple miles on the Talkeetna we hiked over to Clear Creak and floated (Class III) out to the town of Talkeetna. This a great traverse of the Talkeetnas and could be an Alaska Classic.
