Turnip rock is a small Natural Geological formation known as a Stack (a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion) located in Lake Huron in shallow water a few meters offshore near the rock known as the Thumbnail.
Due to wave erosion Turnip Rock has been severely undercut by wave action. So the top of the rock has a significantly larger cross section comparing with its base. This has given itself a very unusual look and has made it a popular tourist attraction.
Turnip Rock is entirely located on a private land and a concrete collar has constructed around the base of the rock at the water level to prevent further undercutting of the rock.
