This photo comes to you from Canyon Falls, a lovely waterfall near Baraga. The waterfall, as its name implies, falls into a deep canyon with sheer sides. Well, they aren't quite perfectly sheer -- there are small ledges, and somehow ferns and even small trees have managed to take hold.
The thing that really caught my eye here are the different colors of rocks: orangish-brown above, and grey-black below. Is this an interface between different types of rocks? I suspect it is, since waterfalls like to form where something changes, geologically.
