1. In 1876, the U.S. Senate passed a bill allowing the creation of a commission to survey the boundary line between Idaho and Montana. The commission was tasked with determining the exact location of the 45th parallel, which divides the two states.

2. In 1910, the Idaho State Legislature passed a law allowing women to serve on school boards. This was one of the first states to grant voting rights to women, and Idaho women played a significant role in the suffrage movement.

3. In 1928, the Idaho State Board of Education authorized the establishment of a new public university in the state. What would eventually become Boise State University opened its doors in 1932.

4. In 1945, the U.S. Army established the Idaho Ordnance Works in Bonneville County. The facility was used to manufacture components for nuclear weapons during the Cold War.

5. In 1980, the Mount St. Helens eruption in Washington state resulted in widespread ashfall in Idaho. The town of Stanley, located 200 miles east of the volcano, reported ash accumulations of up to several inches. The eruption had a significant impact on agriculture, transportation, and air quality in the state.
