The Beaumier U.P. Heritage Center is proud to announce the 25th annual Sonderegger Symposium will take place on Friday, November 14. The title of Sonderegger25 is Above and Below the Surface: Maritime History of the Great Lakes and will be held in Northern Center Ballroom IV on the campus of Northern Michigan University. Admission is free and open to the public. There is no need to register.

This year’s Sonderegger Symposium is inspired by the 50th anniversary of the sinking of the Edmund Fitzgerald on Lake Superior but will deal with far more than just that tragic event. The speakers are noted maritime scholars, authors, curators and divers who will present a breadth of knowledge at this year’s event. There will even be a performance of maritime music to conclude the day’s activities.  Click here to see the schedule for the event. To read the bios of this year's speakers, please go to this link.
