EROSION

Canon EOS REBEL XS, Promaster 19-35 lens @ 19mm, ISO 400, f/14, 0.4 sec

  As I said in my last post, I have been to Conasauga Falls on 4 different occasions.  Trying to get a unique shot of the falls becomes difficult. Especially a wide angle complete shot of the falls. You can only look at them from so many angles before you say "Yep, there it is" and your bored with it.
  I think that this image is an exception.
  Every canyon or gorge has been cut from water erosion.  You can see that by the smooth rocks in the rivers and streams and by the shapes of the canyon walls sculpted by the water. When I took this photo, I noticed that the water rushing down the 3-tiered Conasauga Falls pour into a large pool. If you look at the rocks that make up the tiers of the falls you can see what the water has done them.  I then noticed that this pool seems to empty directly on to this small rock before flowing over several more cascades down stream.
  This rock takes a tremendous beating  from the splashing water.  So much in fact that I took several close ups of this rock and you still can't get a good solid shot of rock in any shot. Just a dark spot under the water.  Almost like nature's own version of water boarding torture.  In a few years the rock may shape into a "V" from the water erosion, who knows. Would love to see old photos of this area and see what it looked like 50-100 years ago.
  400 ISO really helps catch the violent splash of water on the rock while still giving a silky flow of water over the falls themselves in the background.
