Grand Mound

Grand Mound is an archaeological site containing multiple earthworks and layered deposits from Woodland period villages. The main structure measures about 140 feet long, about 100 feet wide, and rises about 25 feet high, featuring an extended tail shape with four smaller surrounding mounds.

The site developed during the Woodland period, with settlement and burial activities dating back to around 200 BCE. It later received National Historic Landmark status and is now protected by the Minnesota Historical Society.

Indigenous communities view this site as sacred and use it for ceremonies and educational purposes to honor their ancestors. Public access is restricted to maintain respect for the burial grounds and the people connected to them.

Access is limited since this is an active burial site, with entry restricted to Native American community members and authorized visitors. You should contact the Minnesota Historical Society in advance to ask about visiting possibilities.

This site represents the largest prehistoric earthwork in the upper Midwest and features a distinctive silhouette resembling a muskrat. This rare design makes it one of the most notable examples of prehistoric mound art in North America.
