Late May through early June marks calving season in Yellowstone — when cow elk become fiercely protective of their newborns. Without antlers, they rely on powerful hooves to defend against any perceived threat, including well-meaning visitors. Stay 25 yards back, watch your surroundings at Mammoth Hot Springs, and if an elk approaches, get to shelter fast.
Experience fall wildlife in Yellowstone and Grand Teton, where elk, bison, bears, and golden landscapes work to create nature’s most spectacular wildlife season.
