Maclean has spent nearly four decades paddling rivers and lakes, and he has written this guide for beginning and intermediate paddlers that includes 36 separate treks through Alaska. Each expedition contains detailed river descriptions and maps that show access points, levels of difficulty, optimal flows, rapids and hazards. Appendices include general Alaska paddling information and a suggested packing list that is specific for conditions in Alaska. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
