September is Minnesota Archaeology Month. Each year the Office of the State Archaeologist (OSA) compiles a calendar of events which is then posted on the OSA web site: https://mn.gov/admin/archaeologist/ If you are considering sponsoring, organizing, hosting, or leading an event during the month check out the these downloads for more information as to how to participate and get your event listed on the OSA calendar.
