Bison

This bull elk is on the campsite adjacent to mine.  He sat there over 30 minutes chewing some bark from a tree on the other side of my campsite, just sitting there and watching me (and other campers who came to take his photo.) He has 7 points on one antler and 8 on the other if you are trying to count.

Young elk just starting antler growth.
