Like most wildlife the coat on elk looks the best in winter or spring . In the summer
they can look quite mangy even if they remain unaffected by the disease itself. A snowy background also isolates the animal better.
This large bull was a member of a large group of elk that hang out in Gibbon meadows in late summer and early fall. In the past, large bull elk were more solitary. The introduction of wolves has changed their behavior. In Yellowstone these days, a solitary elk is easy pickings for a wolf pack.
