Gray Wolf, Yellowstone National Park
Many years ago the entire Canyon Pack passed by me at close distance. This was at Twin Lakes. Actually, it happened twice. The other time I was photographing marmots at the north end of Yellowstone Lake. The marmots started screaming like crazy. Then I got a glimpse of a Canyon Pack wolf walking on the other side of the marmots. When that ended I decided to quit. I turned around to go back to my car and, lo and behold, another Canyon Pack member was ambling along between me and my car parked twenty yards away. I had a 500mm lens in one hand and a tripod in the other hand. All I could do was watch as it went by. At least I got the shot above near Twin Lakes.
