|Location||Alpena County, Michigan |
THUNDER BAY (MICHIGAN) Latitude and Longitude:
|Surface elevation||581 feet (177 m) |
Several islands in the bay are protected as part of the Michigan Islands National Wildlife Refuge. Thunder Bay Island lies just east of North Point outside the bay. The wildlife in the Bay's waters are protected as part of the Thunder Bay National Marine Sanctuary.
The name is the English translation of the French Anse du Tonnerre, which appears as early as the map of Franquelin in 1688. It was probably derived from the Native American name, as they believed that the Bay was peculiarly subject to thunder storms.
There are a substantial number of shipwrecks in and around Thunder Bay. Diving is an important activity.
