there is something scrathing at the back of my brain telling me i read a story on these forums some where about a guy finding stone carvings of heads in the desert , he made notes of which direction the 1st one he found was facing then dug it up , he made a drawing of how each one was turn which direction they were facing, if they were face up or down,, he did tons of notes and drawings , seems like he used them to locate a cache of gold.
now this may have been a story about a story this guy heard,, i can not remember ...
but that is the first thing that popped into my old itchy brain when i read you found multiple like this one with the face on it.
