It is estimated that there are about 550 shipwrecks in Lake Superior, most of which are undiscovered. Well, you can scratch a few more off that list as the Great Lakes Shipwreck Historical Society recently discovered three 1800’s-era shipwrecks in Lake Superior near Grand Marais, Michigan.

We've all heard of the Bermuda Triangle but what about the mysterious locale known as the Michigan Triangle? It's an area that stretches from Ludington to Benton Harbor, Michigan, and to Manitowoc, Wisconsin.
