My all time favorite portage is from  the NW corner of Poobah directly north to the Maligne river. It is not on some maps but is on old Fisher maps. I asked Shane Walshe about it when I happened to run into him and he told me it was marked with large blazes every 100 meters or so even though there was not really a trail anymore. A group of 6 of us did it in 1988 by repeatedly sending 2 or 3 scouts to the find the next blaze while the rest of us moved all the gear up to the most recently discovered blaze. The blazes were huge and unmistakable. There is a little lake in the middle with very difficult approaches but it is a charming lake. It dropped us out into wild rapids in the Maligne. It was as fine a day as I have ever had in the wilderness and I would love to do it again but I can't get anyone to agree to go there with me again.
