Buffalo - Henry Mountains

Utah’s Henry Mountain range is home to one of the only free roaming bison herds found on North American public lands. With between 250 and 400 bison at any given time, the Henry Mountains herd are direct descendants of the Yellowstone Park bison, and one of two American bison herds maintained by the state of Utah. Their habitat encompasses the mostly public lands on and very near the Henry Mountains, generally ranging from Blue Bench on the north to Eggnog on the south, and Coyote Bench on the east to Notom Road on the west.

While the terms buffalo and bison are often used interchangeably, it’s bison that are native to North America. The Henry Mountains bison have shaggy coats that shed during summer, stocky legs, and shorter horns. Their habitat is typically open grasslands or desert lowlands, and they often graze on gently sloped mountains and hillsides (with two major grazing areas). Although bison aren’t typically high altitude animals, the Henry Mountains herd can be found grazing up at all elevations, ranging from 4,800 feet to the 11,500-foot peak at Mt. Ellen.

Buffalo have short legs and despite their weight can still hurdle a six foot fence.

At one time, there were as many as 50 million bison roaming in North America, but they were hunted to near extinction by the end of the 1800s, with the exception of the Yellowstone Park herd. Bison were gradually reintroduced in 1941, with 18 bison set free into Robbers Roost. The following year, five more were added to the herd, and then they moved themselves to grasslands near the Henry Mountains and eventually into the mountain range itself. In the mid-1960s, the population had grown to include about 80 bison. The prairie grasslands, alpine meadows, and even desert scrub have proved to be ideal environments for the bison to thrive, and they have stayed there ever since.

The Henry Mountains bison are genetically pure, with no evidence of cross-breeding with cattle, unlike other bison herds. In fact, this herd is particularly healthy, with a high natural survival rate and very few natural predators. The biggest issue to date has been competition with local livestock for grazing, so limited hunting is permitted by special license in order to control the population. It is the only hunt-able free roaming heard in the U.S. Although the mountain is capable of supporting up to 400 bison, the state tries to keep the population around 325. Recent population control efforts also include transplanting excess bison to the Book Cliffs, about 100 miles north of the Henry Mountains.

Roamers by nature, the Henry Mountain bison often cover distances of 20 miles a day. You might spy these elusive creatures along the road or kicking up dust in the distance. And if you do, consider yourself lucky. They typically hang out at higher elevations in the spring and summer, then migrate to the lower, western side of the mountain range in fall and winter. The bison tend to graze at dusk and dawn, and rest during the day. They usually breed in summertime, and give birth in the late spring to early summer and that’s usually the best time to spot them. Some of the best areas to look for the bison are Swap Mesa in the winter, Cave Flat/Airplane Springs in the early spring, and Star Flat/Burned Ridge in the early summer. Keep in mind that these animals are truly wild, weighing as much as a ton and capable of running 35 miles per hour, so view them from a safe distance.

Hanksville and Caineville make a great base for exploring the Henry Mountains.  Hanksville is located at the intersection of Highway 24 and Highway 95. The west access to the Henry Mountains is best if you are coming from Capitol Reef National Park.  For more information about the Henry Mountains bison herd, contact the Hanksville BLM office.  Read more about the Henry Mountains here.
