Looks like the portage put in for the wetland area one has to cross to get to the 270m portage onto Carcajou Lake.  (The end of the 1110m + 530m portage from Greenleaf)

The last time I was at this put in we spooked a mama bear and 2 cubs at that opening in the pines across the meadow. The mama went back 40 or so yards from shore and huffed and puffed. The 2 cubs climbed up the pines right in that opening. Just starred at us for a while before slowly shimmying back down the trunk and running off after mom. It was pretty cool. We also saw a bear on the hydro line while portaging to Greenleaf. Wasn't as cool with that. But it ran off too.
