Lake Michigan, a natural marvel within the Great Lakes of North America, stands out due to its vast size and unique characteristics. This lake, entirely located within the United States, is renowned for its expansive shoreline and significant cultural and ecological importance.
Geography and Features
With coordinates at 44°N 87°W, Lake Michigan is remarkable for being the second-largest of the Great Lakes by volume and the third-largest by surface area. It boasts a maximum depth of 923 feet, an average depth of 279 feet, and spans an impressive surface area of 22,404 square miles. The lake is connected to Lake Huron through the Straits of Mackinac, forming a single hydrological entity.
Hydrology and Climate
Lake Michigan’s unique hydrology features the Milwaukee Reef, dividing it into northern and southern basins.
