The latest from CLUE on the newest shipwreck in Lake Erie “The Lake Serpent

Check out the Toledo Blade news article about Carrie Sowden and MAST. It was published on March 28th, 2017.



In Summer 2016 the Maritime Archaeological Survey Team (MAST) mooring for the Morning Star historic shipwreck (Ohio Archaeological Inventory number 33LN295) served as a platform for collecting water quality data.  In a collaborative effort, the Ohio State Historic Preservation Office connected Stone Laboratory of The Ohio State University, who have water quality probes (sonde), with MAST, who has a submerged anchor block and the technical capability to install the probe.  MAST members deployed the sonde on the Morning Star anchor block Labor Day and recovered it October 1st.

What is MAST?

MAST, the Maritime Archaeological Survey Team is a nonprofit avocational group dedicated to the documentation of Ohio's underwater historic resources. Formed in March of 2000, MAST is composed of volunteer individuals who support and participate in research, documentation, underwater archaeological surveys, and educational workshops.


MAST's ongoing commitment to education includes training new members on skills and techniques used for shipwrecks research, measuring, mapping and plotting. In addition, MAST works to educate our community in our historic underwater resources.

Shipwreck Surveys

MAST's shipwreck surveys have resulted in the several technical reports for shipwrecks such as the Adventure, the Hanna, and the F.H.Prince.  Additionally, these shipwrecks have been registered as official archaeological sites with the State of Ohio. MAST has also worked to produce underwater slates for the sites surveyed.
