I revisited the original, and have included a new crop, which I think is a much stronger composition, and get rid of the out of focus log in the immediate foreground. I've also done a quick B&W conversion, but I think it gets too cluttered, there is too much structure for me. However, looking at it some more, it could be an avenue worth pursuing.
Regarding the light as Jeremy noted, I went there specifically as some heavy clouds were slowly breaking apart, and looked very interesting, the park itself is in a small canyon like valley, with very interesting cliffs in parts. My intention was to get a wider shot with the cliffs ("organ pipes") in the foreground and the amazing clouds, but I got there about 10 min too late, and all had cleared to blue sky.
I also tried cropping without the to third, but I find its just a photo of nothing really then, it didn't do it for me so to speak.
Thanks again for looking
