The Henry Mountains offer a unique experience to hunt free ranging bison. Several mature bulls roam the unit and different herds can be found. Some of the bison live in steep and rugged terrain making for a physically challenging experience. Some hunters use horses to hunt the remote canyons of the unit during late seasons.

This unit is strictly managed for trophy-class animals, giving hunters an opportunity for a once-in-a-lifetime trophy. Bison are found in different elevations at different times of the year.
