Most rock formations in areas like this have names. Use google maps, turn on the wikipedia markers and the photograph markers, and locate the rock and find out what it's name really is. If you don't use it in the title, include it in the tags, at least. Likewise, all of these titles would make good tags.
How about "Totems" or "Totem"?
