Mackinac Island (pronounced /ˈmækɨnÉ”Ë/ MACK-in-aw) is an island covering 3.8 square miles (9.8 km²) in land area, belonging to 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.[1] 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.[2]
In the late 19th century, Mackinac Island became a popular tourist attraction and summer colony. Much of the island has undergone extensive historical preservation and restoration; as a result, the entire island is listed as a National Historic Landmark. It is well known for its numerous cultural events; its wide variety of architectural styles, including the famous Victorian Grand Hotel; and its ban on almost all motor vehicles. More than 80 percent of the island is preserved as Mackinac Island State Park.



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 lakeshores date to about 10,000 years ago, and the Nipissing shorelines formed about 12,000 years ago.[52] 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.[53]
Following the Civil War, the island became a popular tourist destination for residents of cities on the Great Lakes. Much of the federal land on Mackinac Island was designated as Mackinac National Park in 1875, just three years after Yellowstone was designated as the first national park. To accommodate an influx of tourists in the 1880s, the boat and railroad companies built hotels, including the Grand Hotel. Souvenir shops began to spring up as a way for island residents to profit from the tourists. Many wealthy industrialists built summer cottages along the island's bluffs for extended stays. When the federal government left the island in 1895, all of the federal land, including Fort Mackinac, was given to the state of Michigan and became Michigan's first state park. The Mackinac Island State Park Commission appointed to oversee the island has limited private development in the park and requires leaseholders to maintain the island's distinctive Victorian architecture.[3][20]
Motor vehicles were restricted at the end of the 19th century because of concerns for the health and safety of the island's residents and horses after local carriage drivers complained that automobiles startled their horses. This ban continues to the present with exceptions only for emergency and construction vehicles.[21][15]
As the Great Lakes assumed their present levels, Mackinac Island took on its current size.[1] The steep cliffs were one of the primary reasons for the British army's choice of the island for a fortification; their decision differed from that of the French army, which had built Fort Michilimackinac about 1715 near present-day Mackinaw City. The limestone formations are still part of the island's appeal. However, tourists are attracted by the natural beauty rather than the strategic value. One of the most popular geologic formations is Arch Rock, a natural limestone arch, nearly 150 feet (45 m) above the ground.[2][54] Other popular geologic formations include Sugar Loaf and Skull Cave
