Lake Huron

Lake Huron is one of North America's five Great Lakes and forms much of Michigan's eastern boundary. Shared by the United States and Canada, Lake Huron is the second-largest Great Lake by surface area and contains the world's longest freshwater shoreline.

The lake borders Michigan's Upper Peninsula and eastern Lower Peninsula, extending from the Straits of Mackinac southward to the St. Clair River. Lake Huron is renowned for its islands, bays, shipping routes, fisheries, beaches, and historic coastal communities.

Hydrologically, Lake Huron and Lake Michigan function as a single body of water connected through the Straits of Mackinac.

—

Lake Huron contains approximately 850 cubic miles of freshwater and is connected directly to Lake Michigan through the Straits of Mackinac.

Lake Huron borders:

* Michigan * Ontario

The lake connects to:

* Lake Superior through the St. Marys River * Lake Michigan through the Straits of Mackinac * Lake Erie through the St. Clair River, Lake St. Clair, and Detroit River system

Like the other Great Lakes, Lake Huron was formed during the last Ice Age.

Retreating glaciers carved deep basins and valleys approximately 10,000 to 14,000 years ago. As the glaciers melted, water filled these basins, creating the Great Lakes system.

Lake Huron continues to shape its shoreline through:

* Coastal erosion * Sediment deposition * Water-level fluctuations * Seasonal ice formation

—

Lake Huron contains one of the most complex shorelines of any Great Lake.

Major geographic features include:

* Saginaw Bay * Georgian Bay * North Channel * Straits of Mackinac * Thunder Bay * Mackinac Island

The lake contains more than 30,000 islands, making it one of the most island-rich freshwater bodies in the world.

Lake Huron contains one of the highest concentrations of shipwrecks in North America.

Notable wreck sites include:

* Thunder Bay National Marine Sanctuary * Hundreds of preserved historic wrecks

The lake's cold, freshwater environment helps preserve vessels for decades and, in some cases, centuries.

Thunder Bay is frequently referred to as “Shipwreck Alley” due to the large number of vessels lost in the area.
