Jay Hanson from North Shore Scenic Cruises has helped the GLSPS on many projects. Jay has many years of experience as a Captain, dive shop owner, dive instructor and commercial diver.

Jay has taken a different path for the past few years and his scuba charters are no longer available. However, in 2012, Jay purchased the Wenonah which was previously used to transport people from Grand Portage, MN to Isle Royale, MI. He now offers day cruises on the North Shore of Lake Superior and is docked at the Silver Bay, MN Marina.

For the last two years the Wenonah has been laid up in dry dock to replace the entire steel bottom of the boat in order to pass the Coast Guard Safety Inspection. 
The Wenonah will hopefully be ready for service in 2020.

If you are interested in booking a 2 hour - day charter cruise on the North Shore of Lake Superior, please click on the logo above for information on joining him and his staff on a north shore day cruise.

Closing Report:

We were very successful in locating several knees from the schooner ELGIN and a hatch combing, hull section, bow section and several metal pieced and timbers from the steamer LIBERTY. The most significant find was a very large section of the hull side, including the rail from the steamer LIBERTY. 

No one was aware of this piece that is the size of a full size pickup truck. Coordinates for each piece were pinpointed by the diver, photographed underwater and recorded on a list.

While we did not find the rudder, it is most likely buried in the sand.  The last time I saw it, it was almost fully covered then and easy to miss. This large heavy artifact may be the most at risk, considering the plan drawing provided by the Campground/Marina manager.  The "L" shaped extension of the rock rubble breakwater that will be added near the new launch ramp docks, with direct boat traffic toward the rudder location.  This could be difficult to dive safely as a consequence. I will contact the MHS SHPO archaeologist regarding this to consider potential options to protect this artifact and keep access available to divers.

I will summarize our project and post more of it in this closing report.  I will also assemble a brief PowerPoint presentation to share with GLSPS members at Friday Night at the Movies at the next UMSAT Show in 2020.

We made the decision to wrap up the project Saturday. The heavy thunderstorm that came through late Saturday night dropped a lot of rain. Diving on Sunday in the harbor would have been very poor visibility as a result.
Thank you all very much for your outstanding participation in the Grand Marais Shipwreck Artifact Harbor Survey in completing this important project successfully.

Best regards,
