This image shows two of the three main cascades of the lower falls. The color of the water as it passes over the falls here is a result of tannin released by leaves falling into the river along its course.

The description on the back states:
LOWER TAHQUAMENON FALLS
In Michigan’s Upper Peninsula
Sometimes referred to as “the root beer falls”. It is an interesting fact that actually there is a greater volume of water going over the lower falls than the upper. Many people enjoy wading in the shallow waters beneath the falls.
