"North to Athabasca" IS the book you are looking for if you are seeking a canoe-camping escape from the winter doldrums. This is especially true if you are ready to experiment with river canoe trips way up north.
David Curran & his paddling partner from Massachusetts were seeking a remote northern paddling experience. They had moderate canoeing experience but, really, the most they had ever done before was the Allagash Waterway in Maine (which he had written his first book about... and which I, myself, paddled 30 years ago). They settled on the McFarlane River, which dumps into Lake Athabasca in northwestern-most Satchkatchewan. Only a couple of non-First Nation folks had ever attempted it before so information was sketchy, at best, regarding portages, navigability, etc. There were some rough canyons to negotiate, several wildlife encounters, some interesting logistics issues, and challenging paddling conditions throughout. It is a very engaging accounts of their trials, none of which were truly exceptional but all of which will be appreciated by experienced QJ paddlers.
Curran writes in an engaging style. He has a good sense of humor. He digresses a lot, wrapping stories from his childhood, etc., into his tale. Nevertheless, I found myself fairly engrossed in this book. It was surely what was needed on this, the coldest day of the year (thus far) here in the frozen wastelands of MN. This is not the best book I have ever recommended in this forum but I certainly rate it as a "very good read". Those of you like me (& KF & dd & MP & MT & nctry_Ben & others) who find themselves creeping ever northward in their canoe camping ventures will DEFINITELY enjoy this book.
Now there's not much in this book on the fishing; mostly it's about the exploring & the challenges. Curran does a good job of putting the reader in his mind as he plans, then paddles this very challenging route. While it turns out to be a fairly short trip, the account is one of a trip very full of experience & discovery.
Get it from your local library for a winter weekend read. You will not be disappointed. This gets a big thumbs up!!
