The 1km portage next to that is a former road from that structure, and is about as straight, wide, even, and smooth as it gets. So, there was no excuse for me, in 2016, when I fell on that trail with the canoe. I stepped on a little nub of a root, slightly larger than the size of a knuckle on your index finger, and it was just enough to buckle my ankle and I went down in a heap. Proud moment.
