Description
View from a porch on Mackinac Island of The Mackinac Bridge, Michigan.
Mackinac Island is an island and resort area covering 3.8 square miles in land area, part of the U.S. state of Michigan. It is located in Lake Huron, at the eastern end of the Straits of Mackinac, between the state's Upper and Lower Peninsulas. The island was home to a Native American settlement before European exploration began in the 17th century. It served a strategic position amidst the commerce of the Great Lakes fur trade. This led to the establishment of Fort Mackinac on the island by the British during the American Revolutionary War. It was the scene of two battles during the War of 1812.

Mackinac Island was formed as the glaciers of the last ice age began to melt around 13,000 BC. The bedrock strata that underlie the island are much older, dating to Late Silurian and Early Devonian time, about 400 to 420 million years ago. Subsurface deposits of halite (rock salt) dissolved, allowing the collapse of overlying limestones; these once-broken but now solidified rocks comprise the Mackinac Breccia. The melting glaciers formed the Great Lakes, and the receding lakewaters eroded the limestone bedrock, forming the island's steep cliffs and rock formations. At least three previous lake levels are known, two of them higher than the present shore: Algonquin level lakeshores date to about 13,000 years ago, and the Nipissing level shorelines formed 4,000 to 6,000 years ago. During an intermediate period of low water between these two high-water stages, the Straits of Mackinac shrank to a narrow gorge which discharged its water into Lake Huron through Mackinac Falls, located just east of Mackinac Island.
