The waterfalls on the Black River are very different than most of Michigan's waterfalls. Instead of jagged or sharp rocks, the falls are surround by conglomerate rock, which is a smooth rock created by the compression of many smaller pebbles (among other things). Of all of the falls on the Black River, Gorge Falls is my favorite. The gorge the waterfall is found in is really fascinating. I can imagine how the water eroded away the rock to create this beautiful area.
