NABSQNO 16T-543097-5155155. Chapel Rock is a double sea natural arch eroded through an old stack of Munising Formation sandstone. Because of the tree growing from the top of the stack, this feature is sometimes called The Flower Pot. Undoubtedly, the root system of this tree has stablized the stack and lengthened the lifespan of the arch. It is located on Lake Superior along the coast of Michigan's Upper Peninsula and is one of the many attractions of Pictured Rocks National Lakeshore. Access is via commercial boat tours out of Munising, Michigan. It is listed in the Vreeland catalog as number 14-2. The larger of the two openings has a span of 8 feet and a height of 14 feet. The second opening, not visible in the photo above, has a span of 5 feet and a height of 20 feet.
