Here is a wide aerial shot of the Upper Falls and a considerable extent of the river that feeds the falls. The area is still very wild and preserved as a state park.

The description on the back states:
UPPER TAHQUAMENON FALLS AND RIVER
In Michigan’s Upper Peninsula
The rushing blue waters of the Tahquamenon River winds its way for miles through broad swamps, thickly forested ridges, and between stone cliffs over 100 feet high, where it widens to 200 feet at the top of the Falls, and transforms to a “Golden” color as its turbulent waters plunge approx. 40 feet over a sandstone cliff.
The card is is not dated but is likely from the 1950s.
