About Chinook

Chinook grew around the Great Northern Railway's Hi-Line station, which received its first train in 1887. The railroad placed the town along the Milk River and helped make it Blaine County's seat in 1895. Ranching, livestock shipping, wool, and later sugar beets shaped the local economy around the county seat. The Utah-Idaho Sugar Company opened a beet factory in 1925; it operated for 26 years, and the crop's legacy survives in Chinook High School's Sugarbeeter mascot.

Chinook's museums and county institutions keep that history close. The Blaine County Museum and Blaine County Wildlife Museum sit in the town center, alongside the Blaine County Library. Sixteen miles south, Bear Paw Battlefield marks the final battle of the Nez Perce Flight of 1877, where the Nez Perce laid down arms after a five-day battle and siege; the National Park Service keeps staff offices in Chinook. That connection puts a Hi-Line county seat, a local museum cluster, and a nationally significant Nez Perce history site on one map.
