Here’s a color check-in from last week on Mackinac Island. The Mackinac Island State Park Commission says the following about Sugar Loaf rock romation:
Sugar Loaf, a 75 foot tall limestone stack, is the largest rock formation on Mackinac Island. When glacial Lake Algonquin covered much of the Island 11,000 years ago, Sugar Loaf was connected to the nearby bluff face (today called Point Lookout). Wave action slowly washed away the softer limestone between the stack and the bluff, leaving Sugar Loaf as a stand-alone feature. High water levels during the Lake Algonquin period left only the top of Sugar Loaf exposed, as evidenced by the small cave cut into the north face of the formation by wave action. This cave was originally on the shoreline of the lake.
As with other geological features on the Island, numerous Native American legends have been passed down relating to the origin of Sugar Loaf. One story relates that a young man asked the spirits for eternal life. In response, they turned him to stone, creating Sugar Loaf.
