Bison are the easiest of the big mammals to see in most of Yellowstone as they sometimes hang out in large groups near the road. They generally leave people alone but seem so docile that inevitably someone will get too close and end up getting hurt. It’s not so easy to underestimate them on the trails, however, where it’s hard to ignore their size and speed. And of course the horns. You are in their domain and there is no car to retreat to.
This was one of a group of bulls that was coming in my direction on the Storm Point Trail. While you are supposed to stay on the trails in Yellowstone, I decided to let the bulls have the right-of-way and stepped into the meadow. However, they soon veered off the trail themselves to go for a romp in the wallows so I was able to safely continue down the trail.
