Turnip Rock is a small geological formation in Michigan.
It is a turnip-shaped limestone stack.
Located in Lake Huron, in shallow water a few yards offshore, near the rock called the Thumbnail which is the extreme tip of Pointe Aux Barques, a small peninsula which is also the extreme tip of Michigan’s Thumb.
Turnip Rock has been severely undercut by wave action, so that its top has a significantly larger cross-section than its base.
Turnip Rock can only be accessed via water, and there is no public road access. It’s about 7 miles off the coast of Port Austin.
