August 19, 2020 while driving through Hayden Valley we happened upon this bison fight. I got everything but the first clash. You never know what you will see during the bison rut in Hayden Valley. One thing we have learned in our time working at Yellowstone is that you always leave extra time to get through the valley. Bison are notorious for stopping in the middle of the road. Luckily, the female who caused this jam also allowed up to capture this entire bison fight.
