A previous friendship circle. The Winona-Dakota Unity Alliane will gather for its traditional celebration this weekend at Lake Winona’s east end. The theme: “Back to the Land.” Events include drums and dancers. Time: 1 p.m. on Saturday. The city has a covenant with the Dakota people to preserve and protect the natural environment surrounding Winona. This includes burial grounds and archaeological sites. Wapasha Prairie had been a seasonal home for the Dakotas until the 1860s when federal troops forced them into a forced match to resettle in arid several hundred miles west. Many didn’t survive.
