Introduced to the public in 1980, the Post-it Note has become one of the Minnesota-based 3M Company’s most successful products.

The Duluth, Missabe and Iron Range Railway (DM&IR) was a small railroad that hauled iron ore and taconite from the mines of northern Minnesota’s Mesabi and Vermilion Iron Ranges to docks on Lake Superior at Duluth and Two Harbors. It operated in northern Minnesota and Wisconsin.

The Great Northern Railway was a transcontinental railroad system that extended from St. Paul to Seattle. Among the transcontinental railroads, it was the only one that used no public funding and only a few land grants. As the northernmost of these lines, the railroad spurred immigration and the development of lands along the route, especially in Minnesota.

The world's largest peace pipe began with a vision shared by three spiritual people: one Lakota and two Anishinaabe. The pipe stands on the grounds of the historic Rock Island Railroad depot near the entrance to the Pipestone National Monument, home to the Keepers of the Sacred Tradition of Pipemakers. The location of the giant peace pipe is significant; the pipestone quarry nearby is known as "the crossroads of the Indian world." The soft red stone from the quarry has been used by American Indians for thousands of years to create ceremonial peace pipes.

On November 6, 2012, Minnesota voters rejected a proposed amendment to the state’s constitution. Minnesota Amendment 1, also called the Minnesota Marriage Amendment, would have limited marriage to heterosexual couples. When the amendment failed to pass, Minnesota became the first and only state to reject a "same-sex marriage" ban through the will of voters rather than a court ruling.

The Luce Line Railroad, known by several different names, was a small rural Minnesota railroad that operated through much of the twentieth century.

Platteville limestone is a distinctive building stone of southeastern Minnesota and southwestern Wisconsin characterized by its gray color, rough texture, and many fossils. It was heavily used in the early decades of the building of the Twin Cities and Faribault.

The Minneapolis, Northfield and Southern Railway (MN&S) was a Minnesota short-line railroad that operated between the cities of Crystal and Northfield from 1918 until 1982. It was a profitable bridge line, routing traffic past the crowded freight yards of the Twin Cities onto connecting railroads at Northfield.

From the time of statehood into the early 1900s, Minnesota's climate discouraged the growing of corn. Many immigrants from Northern Europe disbelieved the skeptics and set out to prove them wrong by developing special varieties of seed capable of growing corn in cold conditions. They were successful, and by the late 1930s, Minnesota had become one of the leading corn-producing states.

A gilded quadriga sculpture group titled "The Progress of the State" stands like a sentinel over the front façade of the Minnesota State Capitol. Architect Cass Gilbert commissioned Daniel Chester French, best known for the Lincoln Memorial in Washington, D.C., to do the work. He sculpted the chariot and human figures, and animal sculptor Edward Clark Potter created the horses. The quadriga (Latin for "four-horse chariot") has greeted capitol visitors since its installation in December 1906.
