While I like both I am leaning toward the first post as I prefer the way the swirls fill the FG, Mike. I also like the POV as it is not one I have seen of Adams Falls before. Looks like the low flow levels reveled some different rock structures to photograph. My only suggestion would be to tame the whites a little, but that certainly is not a big deal. Beautiful take on this.
The bottom half of the first picture, just the swirls with a bit of dark above. But if I had to accept the image untouched it would be the second picture because the swirls are so powerful in the first image that the composition feels unbalanced.
