Geo 1095: January 11, Day 741: Falls and Fronds

Another shot of North Falls, which I really like for the way the fern fronds mimic the form of the waterfall. Once again, you can see the relatively thin dark layer of sediment that is the weak zone in this stack of rocks. As I discussed in an old post, the "hard over soft" arrangement of rock layers is, to my mind, the "classic" set-up for a waterfall.
