Los naufragios de los Grandes Lagos (Great Lakes Shipwrecks) [PDF ebook] 

The Great Lakes are the largest group of freshwater lakes on Earth and have always been important channels of shipping and trade. Though they are lakes, their waters have proven to be as challenging as the oceans. That’s why there are more than 6, 000 shipwrecks in the Great Lakes! This captivating book relates the stories of some of these wrecks, including the Edmund Fitzgerald, Argo, and Lady Elgin, their survivors, and the not-so-lucky. It also explains how wrecks are found and what happens after their discovery. Amazing photographs and sidebar information will provoke readers’ imaginations about these undersea artifacts.
