Occasionally waves attacking a narrow headland break through to create an arch. This arch is not on a seacoast, however, but in Lake Superior. It is located in Pictured Rocks National Lakeshore, Michigan. The rock is soft yellowish sandstone of late Precambrian age, about 700 million years.

Location: 46^o 33' 06"N 86^o 28' 09"W
