カヌーキャンプと荒野クルージングに必要なテクニック（地図の見かた、川の流れのよみかた、事故の対処法など）を詳細に紹介した指南書です。

When books begin to appear on a subject that has had limited media coverage, the first one is usually pretty good. It has no competition, and the lack of public awareness of the subject means that the first book can be relatively rich. That book is followed by many imitators hoping to cash in on its success. The best of those advance the state of the art in tiny increments as various viewpoints and techniques are presented. Then somebody gets it all together and says, "This is it, for now." This is that for now. And a special mention must go to the illustrations, which are quite exceptional.
