Sugar Loaf

Sugar Loaf stands seventy-five feet above the surrounding level and is the largest of Mackinac Island's many limestone stacks. It was originally connected to the high cliffs directly behind you. More than 11,000 years ago, the erosive power of ancient Lake Algonquin washed away the softer material around Sugar Loaf and created this isolated stack. The small cave in the north face is near the level of the highest shoreline.
