I just love waterfalls, and this one — Deep Creek Falls — was fascinating simply for it's unexpected appearance and basalt-column goodness.
So we turned around, pulled into a small pullout on the north side of the road, climbed over the guard rail on the other side, and I took a few pictures as the light moved across the landscape.
Stop here to see the falls (and some interesting polygonal cracks in columnar basalt on the side of the road).
The basalt columns in at the falls don't seem to show the polygonal cracking seen in exposures on the side of the road — they are either eroded and somewhat subdued if caused by water during basalt cooling, or they are not present because they haven't yet had the chance to be exposed to the forces that create spheroidal weathering. You Choose! (I would have to back and do some mapping and maybe some detailed whole rock sampling or petrography to decide.)
