Sweet Grass County Fair

On the Monday of the Sweet Grass County Fair, the horse show starts at 9 a.m. and is the only event of the day. That was the opening of the 2026 fair, which ran Monday, July 20, through Friday, July 24, in Big Timber. The rest of the week fills up around the showring. Marc King, the Sweet Grass County Extension Agent, counted the stock before the 2026 fair began: “There are 19 steers, 33 lambs, 38 hogs and, of course, breeding projects. There’s probably close to 120 students across 4-H and FFA.”

Five days in the showring

On Tuesday, July 21, indoor exhibit interviews began at 8 a.m. They are closed to the public. At 1 p.m. the small animal show brought out cats, rabbits and chickens. In the 2025 competition the top cat was Cinder, shown by Claire Seleasen. From 5 to 7 that evening came weigh-ins for swine, lambs and goats and a handling review for beef and breeding stock. Every animal had to be in place by 7.

On Wednesday, beef showed at 8 a.m., goats at 1 p.m., and dogs closed the day’s showing at 4. Fun night started at 7, an evening set aside for the kids to play games and unwind after a day in the ring.

Thursday began with swine at 8 a.m., and the sheep handlers entered the ring at 1. At 4:30 came the Knapweed Contest and Cloverbud Showmanship. Cloverbuds are five- to eight-year-olds who learn through group activities before they are old enough for the full 4-H program, which takes young people from 9 to 19. The FFA Alumni sponsored a dance and band to close the day. “It’s a chance to have some live entertainment at our fair,” King said. “It’s a way to draw some people down to our fair and make some money.”

Friday opened at 9 a.m. with a round robin, small animals first and then large. The awards program followed at 1 p.m., then a buyer’s barbecue from 4 to 6. The auction awards and introductions began at 5:45, and the auction itself at 6. All week the concessions sold for the benefit of the Class of 2026. “It helps put on their graduation party and keeps them out of trouble,” King said.

Barns, arenas and the Ag Pavilion

Big Timber lies in the valley where the Boulder River meets the Yellowstone, between the Crazy Mountains and the Absaroka-Beartooth range. The town takes its name from the cottonwoods along both rivers. The county fairgrounds have a rodeo arena with grandstands, an infield, an announcer stand and a walkway behind the chutes. There is also a cutting arena, a canopy over the Horse Whisperer Arena, livestock barns and outdoor stalls. Other buildings include the Ag Pavilion with its kitchen and grill, the Old Exhibit Building and a beer garden building. The grounds also have lawns, a picnic area and camping at $10 a night. Outside fair week the county rents the facilities out, and the grounds host events through the year, among them the annual Big Timber Bull-a-Rama.

A county Fair Board oversees the grounds. Its five appointed members include Nathan Ruth and Rocky Cosgriff, both appointed in 2017. King sits on the board ex officio, alongside a representative of the county commissioners. King has said what the week is for: “Our county fair is a chance for our community to get together. A lot of people in agriculture don’t come to town unless they need parts, so this is a great way for everyone to get together and see their neighbors.”

What the Friday sale pays for

Montana State University Extension, which runs the 4-H program through its county office, calls the fair the culmination of the members’ project work. The young exhibitors present their projects for judging and practice interviewing and salesmanship along the way. The Sweet Grass County Fair Sale wraps up the week. Members sell their finished projects to the community, and the proceeds go to them, typically to pay for their further education. During the 2024–2025 4-H year, 26 registered volunteer leaders mentored 127 youth enrolled in Sweet Grass County 4-H. The 2025 sale grossed $464,000.

In 2020, many Montana counties held their fairs virtually. Sweet Grass County worked with local officials on safety protocols and held its fair in person, altered in some respects from the usual. The livestock shows were livestreamed so the community could watch from home. The sale was held in person with social distancing, and it sold 204 lots for a gross of $340,126. The Extension office ranked it at the time as the top-grossing sale in the fair’s history.

Herefords and giant pumpkins, 1909

Sweet Grass County was formed in 1895 from parts of Park, Meagher and Yellowstone counties. MSU Extension says that in the early 1900s it was the largest inland shipping point in the United States for raw wool. Montana’s Yellowstone Country goes further and calls the county once the world’s largest exporter of wool, shipping more than a million pounds a year. The Extension office in Big Timber still grades, cores and ships wool from the co-op-owned Sweet Grass County Wool Warehouse.

The fair was already well established in those years. On September 23, 1909, the Big Timber Pioneer reported on the sixth annual Sweet Grass County Fair, put on by the Sweet Grass County Fair Association. The paper described large crowds, perfect weather, and record-breaking displays of crops, livestock and crafts, with Livingston and Melville Days adding to the turnout. Farmers showed giant pumpkins and cucumbers, along with heavy Herefords and Shorthorns. The horse show was lively, with several notable races.
