Thanks catees and Sycamore for sharing. I would like to additionally thank Sycamore for carting out trash and spreading good vibes. I personally do not see rck stacking as graffiti. I know some people would even consider human footprints as invasive. However I believe the Lord created the world for us to live habitat in harmony with his creation. The question is where do we draw the line? In my opinion, anything that is distructive to the enviroment like trash, fires, grafitti, etc. is out. Rockstacking, like painting mud faces on the rocks, or footprints on the sand are not permanent and the forces of nature in the not very long future wash them away. I have seen rock stacks been knocked over by the wind while I have been at the Springs. Therefore, in my opinion rockstacking is not a form of grafitti. LOL.
