in the Lamar Valley in the northeastern part of Yellowstone National Park. I spent an entire day observing about 500+ bison in several small herds, only about a tenth of the total estimated population in the park.
The majestic American bison (Bison bison).
Typical scene in Yellowstone: Always yield to a huge animal with horns when it decides to cross the road.
Lip-smacking good.
Time for a dust bath.
