1. In 1909, the Billings Gazette reported that the harvest of sugar beets in Montana had set a record, with a total of 146,825 tons being produced during the growing season. This was a significant increase from the previous year's harvest, which had been 100,000 tons.

2. In 1940, the town of Fort Peck was officially incorporated. The town is named after Fort Peck Dam, which was constructed between 1933 and 1940 and is one of the largest dams in the world. The dam was built on the Missouri River in northeastern Montana as part of the New Deal's efforts to create jobs and provide irrigation for agriculture.

3. On November 27, 1961, the Anaconda Copper Mining Company announced that it was going to shut down its copper smelter in Anaconda, Montana. The closure was due to a decline in demand for copper and increased competition from foreign producers. The smelter had been in operation since 1884 and was the lifeblood of the Anaconda community.

4. in 1978, a major winter storm hit Montana, causing widespread damage and disruption. The storm, which is now known as the Thanksgiving Blizzard, brought heavy snow and high winds, causing power outages and closing roads and schools. It was one of the worst winter storms in Montana's history.

5. In 2009, Montana State University's football team won the Big Sky Conference championship, earning a berth in the NCAA Division I Football Championship Subdivision playoffs. The team went on to win its first-round game against Texas State University but was eliminated in the quarterfinals by the University of New Hampshire. It was the team's sixth appearance in the playoffs and its first since 2006.
