Wonderful report!
I was thoroughly absorbed in this trek. In 2008 I paddled Carcajou Creek to the point where the road crosses it and remember the spot where the old bridge would have crossed the road. At the time, it was obvious where the bridge would have been. I don't recognize the spot in your pictures at all. Amazing how seasons, water levels and time can change the look of a place.
I love the treks you and your brother take. Nice to read the little bit of history at the end of this one.
