Anyone contemplating writing a wilderness canoeing guide would do well to go the distance in emulating this guidebook; it is nothing short of fantastic on every front and especially well-written and organized.
I will also add that it is one of the better "Look inside" presentations I've seen on Amazon. Northern-ish Canada, i.e. the latitudinal belt running across the sub-arctic provinces, is a wonderful part of the globe to explore, especially by canoe, and for its broad range of skill requirements (there are options for every skill level; not everyone is looking for a Class IV or V rapids experience) and this guide covers them all, and more, for Northern Saskatchewan. Ms. Archer also includes considerable, fascinating history regarding the area and the river trips described. Especially interesting is the detailing of where each of the rivers covered fit into both the First Nation's history and the early fur trade voyageurs. I very highly recommend this guide.
