You guys are over thinking the Sand Glyph.
It's just telling you there is a UFO above the Hippy Camp.
Look at the clues the sand Glyph gives you and then look at the Hippy Camp, 3 things match EXACTLY.
Now, whether the Sand Glyph and the "Beam" glyph found on Chiliad are one in the same is something to be debated still.
I wish i can see that?
just taking a guess. are you meaning the 3 things are?
arrow, ufo, wow signal? or the glyph also excluding 1 other?
close to the glyph with the wow signal and the arrow in the sand, there is a [hylon with a red arrow, you follow that direction, it leads you to the hippy camp, but to another red arrow in the entrance of the camp, this time leading us to the north west of the map. We cant assume that the glyph on the sand tells you there is an ufo over the hippy camp because it is pointing at another arrow that leads us elsewhere
