Thunder Bay and Alpena, Michigan is known as "shipwreck alley" but we have more than just wrecks to explore. Most of this video was shot in Middle Island Sink Hole (75'). But some was from a deep sink Robert Ballard's crew found in 2002 (330').

We have an additional collection of 5 or 6 sinks just 2 miles from Rock Port ON LAND that are 60' + deep and little explored. (Sink Holes click on the green circles for pictures) And with the water up the Misery Bay sink might again be accessable from the lake as the Township and State of Michigan closed off both land based motorized access points.
