Thanks for the comments.
Your comment is very interesting because several hikers actually stopped to ask what I was photographing even though my camera was squarely pointed at the rock and tree. I'm sure they wanted to tell me I was on the Emerald Pools Trail and that the Pulpit was on the River Walk. Anyway, this was during the second week of Nov. 2008, and the water level was very low. It was also just past peak for fall colors, although this tree looked pretty good in the reflected light from the canyon walls.
Yeah, I need to revisit this one as my photoshop ability and color sense has not caught up to my ambitions for this photo. I am planning to make a few more versions.
