This image shows the breadth of the falls and cascade of the Lower Tahquamenon Falls complex on the Tahquamenon River in the Upper Peninsula of Michigan.

The caption on the back states:

THE TAHQUAMENON FALLS
Lower Falls No. 1
In Michigan’s Upper Peninsula
Largest of a series of beautiful waterfalls, where the River divides to form the enchanting Tahquamenon Falls Island. There are three sets of falls around the island, and several series of rippling cascades. Drive to the “Lower Falls” along the Tahquamenon Memorial Highway (from Paradise to Newberry, north from M-28) then a short trip by rowboat to the Tahquamenon Falls Island for a close-up view of all the waterfalls.

–This image is likely taken from the island itself, looking upstream at the largest part of the falls and complex. The brown color of the water is caused by tannic acid from the decay of leaves from the deciduous trees that line the river.

The postcard is not dated, but most likely dates from the 1950s.
