There is a designation (N32) on the right side of this post (I have a composition from that side, but need different light). Its a smaller and I think older - possibly even original - marking. On many of the pillars I think the markings have been painted over.
Thanks julesfalkhunter. This is an interesting one for me. I loved it when I framed it to make the exposure. I loved it when I first reviewed it. Then doubt crept in. I tried cropping it a variety of ways all of which diminished it. But eventually I came around. I think it took me a while to fully embrace the complexity of it.
