This image is a very 3D looking image and is a remarkable work to be sure.
I too am in CA but in the San Jose area.

That is one heck of a deep shot and maintains fantastic detail so as to draw you into the bubble to inspect the fine wall there to the right.
I have a medusa shot in progress but now I think I will just erase the entire folder.
