Arch Rock

One of the most photographed spots on Mackinac Island, Michigan is Arch Rock. This geological wonder is a natural limestone arch that was formed during the Nipissing post-glacial period when high Lake Huron levels and wave action created openings in the rock. Arch Rock stands 146' over the Lake Huron shoreline--nearly 15 stories tall. The opening spans 50' at its widest point. In Anishinaabe-Ojibwa tradition, the Great Creator blew the breath of life into the newly formed earth and created Arch Rock. Like nearby Devil's Kitchen and Sugar Loaf, Arch Rock's limestone formation took thousands of years by wind, water and receding glaciers to be created. It is made of breccia limestone, a rare limestone for the Great Lakes. The limestone formation was so unique that it was one of the reasons early Mackinac Island residents lobbied for the island to become Mackinac National Park in 1875, and then Mackinac Island State Park in 1895. Arch Rock is located along Arch Rock Road on the southeast portion of the island and offers sweeping views of Lake Huron and Canada.
