This image shows a rocky promontory called Black Rocks, a large outcropping of rocks on Presque Isle Park, on the Lake Superior shore of the Upper Peninsula of Michigan.
The description states:
A herd of native deer rooms the primeval forests of this beautiful peninsula located north of Marquette, and the waves of Lake Superior, pounding against the picturesque crags and cliffs, extend on ever ready welcome to all the pleasure seekers who invade this region.
–These rocks are at times several meters above the lake surface, and many come to dive or jump from the cliffs into the deep lake.
This card is likely from the 1950s.
