There were a lot of sweepers but the river rose enough that it was fairly wide and we had no trouble getting around them. As far as snow/Ice we never had any, not sure when the rivers freeze over but I would guess it is much later. I have attached a few more photos, one is of the two bullets I recovered from my moose. I was using a .338 Win Mag with 210 grain Barnes TTSX, both bullets penetrated the entire width of the moose and lodged just inside the hide on the opposite side, one broke both shoulders. Both bullets had 100% weight retention. I didn't need to shoot more than once but I didn't want him to stumble into the river.
