The rich tapestry of Alaska is threaded together by 365, 000 miles of waterways, from cascading mountain streams to meandering valley rivers, from the meltwaters of glaciers to broad rivers that empty into the sea. This guide profiles a wide variety of rivers from all over Alaska, concentrating on trips for intermediate boaters, and including a few major expeditions for the experienced river-runner. A section on gear outlines what to take into the backcountry.
