Only had time to work a couple of the side-canyons. Think this is the third one from the north-east. Find myself usually walking around with the eyes open, but never see the subtle. Did not catch this collection until on the way out the canyon. It is obvious while positioned across from it, but nearly invisible while on either side. The small green tree mid-right in this photo is the same tree as the one positioned dead center in the this photo where the ruins are not visible.
