into a steep gorge, creating masses of foam as the water falls against the rocks below. Sandstone Falls drops a total of in two sections, a initial drop (pictured) and a second drop. Sandstone Falls is named for the sandstone rocks along the riverbed that the river has cut channels through. Rainbow Falls Rainbow Falls is the northernmost waterfall on the Black River, less than from Lake Superior. It is also the highest. Here, the water drops down into a rocky gorge. The waterfall creates much mist, which, on sunny days, creates a constant rainbow. The approach to this waterfall is strenuous: 200 steps are built on staircases and into the side of the hill, creating a very steep approach.
