Minn. Stat. § 365.28: PUBLIC BURIAL GROUND BECOMES TOWN PROPERTY AFTER TEN YEARS.

A tract of land in a town becomes town property after it has been used as a public burial ground for ten years if the tract is not owned by a cemetery association. The town board shall control the burial ground as it controls other town cemeteries. A town that has accepted responsibility for an abandoned cemetery may prohibit further burials in the abandoned cemetery, and may cease all acceptance of responsibility for new burials.
