GoWaterfalling’s page on Gorge Falls says:
A very scenic waterfall set in a very scenic gorge. An added plus is the close proximity of the equally impressive Potawatomi Falls. These are two of the most impressive falls on the Black River and are also the two easiest to access.
Gorge falls is named for the deep and narrow gorge above and below the falls. This was my personal favorite of Black River Scenic Byway waterfalls. It is also one of the easier waterfalls to visit, being only a short distance from the parking area. There are a fair number of stairs to the falls overlook. It is only a short walk upstream to see Potawatomi Falls.
