Joe Hannibal will give a presentation on “Bringing Norwegian Millstones to America” later this week.

From 1-2 p.m. Friday, June 14, attendees will learn about these round stones, which can be found in gardens, farms, dry-stone walls and along streams. The event will take place at Livsreise-Norwegian Heritage Center, 277 W. Main St.

Millstones are long rooted in Norwegian culture. On the west coast of the country, especially in communities like Selbu, millstone production lasted for more than 1,000 years before it ceased around 1930, a Livsreise document states.

Many of the stones were brought to the United States by Norwegian emigrants during the 19th century, according to the document. It was a time when commercial mills were scarce, the document states.

“This talk will weave together historical and geological information that tells the amazing story of these stones,” the document states.

Hannibal has research interests in paleontology and geology. He also investigates the origin of millstones in the United States.
