Arch Rock, Natural arch in Mackinac County, United States.
The limestone arch formation rises 146 feet above the ground and spans across a significant portion of the rocky outcrop on Mackinac Island.
The natural arch dates back over 10,000 years to the last glacial period, formed through continuous processes of erosion and limestone dissolution.
Native American tribes considered the arch a sacred location, incorporating its presence into their traditional stories and ceremonies throughout generations.
Visitors can reach the arch through a network of walking trails from downtown Mackinac Island, following a series of stairs through the forest.
The location remains free of motor vehicles, requiring travelers to access the site by bicycle, on foot, or via horse-drawn carriages.
