Thanks to everyone for your feedback about the bush. I played around with a crop last night, and this is what I got. I have other images of the monument, but the light was not nearly as dramatic as it is here.
The image was shot at f/16 - I can go down to f/22, so this is a simple screw-up on my part. This is a lesson in shooting in a destracted state of mind. You make simple mistakes like that. If I'd been paying attention, I could have gotten a bit more DOF from this image.
