It is not hard to find rock and arches at Arches National Park, but finding interesting foreground subjects requires more exploring. I liked this dead tree and worked it against the blue sky over the arch in this picture.
I shot this picture with and without the circular polarizer filter - the difference is dramatic - I didn't keep the light-colored sky shot taken sans filter.
