Antelope Island's Bison Roundup

Ride with the Herd

“We ask when people sign up (for the roundup) if they want to be an aggressive rider or if they want to be a leisurely rider,” says former park manager Jeremy Shaw, who has lead the roundup. “Typically, about 100 people will want to go on the leisurely ride and be close to the bison but not engaged. We take the other 200 and break them into teams and call them a left flank, right flank and center.”

About 50 people are allowed to ride with the core group of riders. “These are the guys that know what they are doing, have done this year after year, know what the bison are going to do, know when it’s dangerous, when it’s safe, when we need to ride harder on one side or harder on the other.”

“It’s something to see cowboys (and cowgirls) chasing 700 bison around with dust flying everywhere and them snorting and hollerin’,” says Shaw. “The goal is to get all the bison into the corral safely and not have any of the riders injured in the process.”

That’s the thing about bison. They’re big animals. Shaw and the other staff say they frequently get asked if the bison are tame. They stress to visitors these are wild animals and caution people not to approach them. Signs are posted throughout the park and the best course of action is to keep a safe distance. Bison can run up to 30 miles per hour, which is much faster than humans. They don’t have to run around obstacles (brush), they rumble through things.

“We bring in every bison except for the mature bulls,” said Shaw. “Any bull three years old or over, we leave out. We don’t really need them. We’re not going to sell them and they don’t need to be vaccinated again. They’re basically breeder bulls and they’re hard to herd, and they’re really ornery when you get them with a bunch of other bison.” Once corralled the bison will have a thorough health check the following weekend, which is also a sight to behold. Two weeks later some will be auctioned off to the public. In 2023, approximately 290 bison were sold to high bidders.

A Spectator Sport

Rose has a healthy respect for the bison. “They’re almost a sexy animal,” she says with a big grin. During her early years on the job that they conducted the bison roundup using vehicles and helicopters. The last time they used vehicles and helicopters Shaw watched a full-grown bull put its horns through the door of a full-size Ford Bronco and almost put the vehicle up on two wheels. “He apparently had enough of being pushed around," said Shaw. This practice stressed the bison and was abandoned for the current roundup procedure on horseback.

Where do Bison Live

Custer State Park in South Dakota and Antelope Island State Park are about the only places where people can actually experience a public bison roundup first hand. Though Yellowstone National Park is home to one of the nation’s most famous free-roaming herds of bison, they are not rounded up.

“If you want to herd wild bison off the range, this is the spot...this is the place,” said Shaw.

“I’ve participated in the Custer roundup by invite,” said Shaw. “When I left Custer, my goal was to make this roundup more organized.” Shaw credits his mentors at Custer with playing a big role in helping to get the event in Utah running more smoothly. Through lessons learned we now limit the number of riders but we still try and invite enough public folks to keep the experience authentic.”

For those interested in participating but not riding, spectators are welcome and encouraged. There are two ways to participate. Individuals may view the roundup from inside or outside their vehicle along the miles of roads that parallel the driven bison. Visitors can find plenty of areas on the island where they can catch all the action from a safe distance.

It All Leads to This

Shaw calls the roundup the culmination of their year. The state park offers a number of recreational events throughout the season and has plenty of other wildlife available for viewing. Hikers, cyclists and photographers are likely to see the island’s namesake pronghorn antelope and mule deer, but the park is also home to bighorn sheep, coyotes, bobcats, badgers, porcupines and numerous birds of prey. But the bison roundup is the crème de la crème and a truly distinct Antelope Island experience. The “roundup is ours,” Shaw said.

“You’re talking about a lake (The Great Salt Lake) just out our back door that’s about the size of Rhode Island — that’s a huge draw in of itself," said Shaw. "Then you couple the island with it and it’s almost a combination that can’t lose. It’s truly like no other place in the world.”

Judy Gardner, the first manager of the Antelope Island Buffalo Grill echoes the same sentiments. “I moved from California to Utah and I claimed the island for myself,” said Gardner. “To find an island out in the middle of the Great Salt Lake that has what this island has, there is no comparison," she said. "I love Yellowstone but out here it’s kind of a home away from home. This is my island!”
