This image shows two lighthouses known as the Bailey Harbor Range Lights, in the Ridges Sanctuary, located on the Lake Michigan coast of Wisconsin in Door County. Clicking on the image will give a larger version, which shows the second light more clearly in the far background among the trees.
The description states:
The Ridges Sanctuary, north of Bailey’s Harbor, Door County, Wisconsin. A natural shrine for the preservation of native wild flowers and animals. Located here are the Range lights built in 1870 to guide ships into the harbor.
–There is a third component of the range lights, located approximately where the photographer was standing, which is a skeleton tower allowing ships to identify the location in less favorable lighting.
This postcard is dated 1962.
