The striking thing to me is that like the Nazca lines
this “message” can only be read from the air or perhaps
some elevated point in which case the letters would have
to have been distorted to compensate for the fore shortening.
Are the markings stretched out in any way?
I’m not sure, and I don’t recall there being a scale, either. Appears to be carved, but into what, and vertical or horz surface I dunno.
