Huge and muscled Bison appear to me to be able to plow through anything. It surprised me, then, to watch them in Yellowstone National Park following deep furrows in deep snow made by other Bison instead of foraging a new path. We were entertained by this herd of mostly cows and calves as they began to stir and start to forage at the start of the day, crusted with ice and snow. This cow follows the path of another Bison, the path of least resistance.
