Those gigantic horns that a Rocky Mountain Bighorn ram carries weigh about 30 pounds. Their bodies are designed to carry the weight. We were so close to these sheep that my Nikon 500mm PF lens was almost too much lens. Had he moved much closer, he would have been out of focus. I was about fifteen feet away from the ram as he munched grasses on the edge of the road just outside of Yellowstone Nationaal Park. This mature ram’s horns show a bit of “brooming,” a term used to describe the frayed ends of the horns that results from wear and tear throughout their lives.
