In the last 20 years or so, we’ve had the opportunity to float some of the great rivers in the U. S. — the Colorado, Rogue and Salmon among them. Our search for something different took us to the Tatshenshini and Alsek rivers, which are large glacial rivers in Canada and Alaska, which gave us sunshine, heat, fog, glacial chill, rain and icebergs. After gathering in Whitehorse, Yukon Territory, we drove to our put-in at Dalton Post, a historic trading post.
