Archaeologists uncover massive 1,000-year-old Native American fields in Northern Michigan that defy limits of farming

  • Archaeologists led by Dartmouth surveyed the Sixty Islands site along the Menominee River in May 2023 using drone-based lidar technology.
  • The survey followed initial mappings and excavations from the 1950s through the 1990s and was prompted by Menominee tribal requests to document their ancestral lands.
  • The team uncovered an extensive raised ridge field system dating from around 1000 to 1600 CE, which covers about 70% of the surveyed 330 acres and includes burial mounds and cultural features.
  • Lead author Madeleine McLeester noted that the extent of farming created by the ancestral Menominee people is much greater—about tenfold—than earlier estimates suggested, indicating a level of labor coordination usually seen in larger, more complex societies.
  • These findings challenge previous assumptions about northern Michigan's agricultural history and suggest reconsidering the extent of pre-colonial intensive farming and social complexity in eastern North America.
