Rut season!! Come stay and see it!! Us is usually a quieter time in the park, too!!
It's difficult to describe if you've never been to Lamar Valley, but you can stand on the north side of the valley and look down across the flat grassy meadows that spread out to the river, and then turn your gaze east and west and as far as you can see there are bison covering the entire valley for miles. The bison bulls have already begun the rut, grunting and growling and in some cases engaging in fatal battles. The cows grazing all day long seem to be everywhere. And by their side, the adorable orange calves follow their mothers wherever they go, stopping to nurse at every chance they get. Truly an iconic American animal and such a joy to observe.
