When the going gets tough, we turn to the ones we love and trust the most in our lives. That’s what I immediately thought of when I had the good fortune of witnessing this family of bison brave a thick, early-season Colorado snowstorm. I had watched the herd for quite a while. At first, these magnificent animals were all dispersed, each minding their own business. But then, something beautiful happened. As the snow started falling ever more violently, individual family members within the herd started to gravitate toward each other in a remarkable display of the power of family bonds.
