Just to the north of Oscoda is Thunder Bay located near a stretch of water that is considered one of the most treacherous in the Great Lakes. Because it is prone to thick fog banks, unpredictable weather, rocky shoals, and strong sudden gales, it has claimed over 200 vessels. Known as “Shipwreck Alley” nearly 100 shipwrecks have been discovered in a 4,300-square mile area in and around Thunder Bay.
