Nikon 5100 with Nikkor 55-300 mm f4.5-6.3 @ 200 mm, 1/15 s/ f6.3, ISO 100. Taken in the Lamar Valley region of Yellowstone Park south of the Slough Creek campsite. The trail went up a hill and the bear appeared half way up the hill from the brush on the left. At the bottom of the hill were two "bear hunters" with their 1000 mm glass chatting about their day. They never saw the bear with its dinner head up the trail and disappear into the brush on the right.
