This summer, the LLHS crew has been back, joined at times by Sue and Steve Mulholland, archaeologists with the Duluth Archaeology Center; David Mather, National Register Archaeologist with the State Historic Preservation Office; and Dr. Howard Hobbs with the Minnesota Geological Survey.
All this year’s excavations have been on land owned by WACC; previous digs were on adjacent land owned by the city of Walker; but LLHS was unable to get permission to continue digging there. Living Water Church also owns property adjacent to the dig sites.
There's a photo of the supposed artifact at that link.
