The postcard photograph shows the natural rock arch, an unusual rock formation near Oak Beach, once located at Loosemore Pointe, just north of Oak Beach in Huron County, Michigan. This site was a well-known local feature along the Lake Huron shoreline in the early 20th century. The arch was carved out of the sedimentary rock bluff by the persistent action of wind, rain, and wave erosion over thousands of years.

Loosemore Pointe, named after a family who owned land nearby, was a popular stop for locals and tourists exploring Michigan’s Thumb coast. The unusual rock formation near Oak Beach attracted photographers and postcard publishers before it eventually collapsed — likely sometime mid-century — due to the same forces that created it.

Today, the arch no longer stands. Rising lake levels, ice pressure, human graffiti, and shoreline erosion erased this once-iconic landmark to a low-lying pile of rubble. This photo postcard stands as one of the few surviving records of the unusual rock formation near Oak Beach, capturing not only the geology of the region but also the early recreational use of Huron County’s lakeshore.
