Arch Rock is an amazing natural rock formation on Mackinac Island in Michigan. It's a giant arch made of limestone, shaped by nature over many thousands of years. This special arch formed after the last Ice Age, when the water levels of Lake Huron were much higher.

Today, Arch Rock stands about 146 feet (45 m) above Lake Huron. It's quite rare to find a natural arch like this in the Great Lakes area. This is because the type of rock it's made from, called limestone breccia, isn't usually strong enough to form such a bridge.
