GTA V - Mt. Chiliad Mural Mystery

Most of the in-game mysteries are believed to have been solved but the so-called "solution" for the Mt. Chiliad mural remains shoddy.  It could be that Rockstar Games has sent its players on a wild goose chase with clues that are intended to confuse rather than be pieced together.  It's also possible that the puzzle has not been solved or can't be solved until a later DLC release.  Have a look at some existing clues in the game...

It begins with Mt. Chiliad and a mural found inside the lift building:

An observation deck atop this mountain offers a message and a red colored glyph painted underneath:

Five (5) white colored glyphs can be seen along the mountain's rocky surface in various locations:

A 6th image of an unidentified face is also located on the rocky surface of the mountain:

The mountain also has the Altruist (cult) Camp which includes several buildings and watch towers:

Underneath the camp, is a shallow cave which is believed to be used for animal sacrifice (has horns):

Both the Altruist Camp and cave have multi-colored glyphs and phrases and here are all of them:

Far east from Mt. Chiliad is the Hippie Camp which features alien writings everywhere:

 

The Hippie Camp shows us two (2) colored glyphs (matching two from the mountain):

 

And a bunch of alien writing:

In this same desert area, there are a few other clues:

 

In the city of Los Santos, another glyph can be found as part of a local business logo:

 

The observatory in Los Santos has something eerily familiar:

 

In the very 1st mission, if you wander off the preset path, you'll stumble on an alien frozen in a river:

 

Then UFOs make an appearance on 8 different occasions starting with a noisy embedded one stuck in a building:

 

Then there's that mission where you're drugged and you somehow get abducted by aliens via their spacecraft:

 

At that Hippie Camp, there's a joke UFO:

 

In another mission, you help reassemble a miniature but fully functional and noisy UFO:

 

When scuba diving, you'll eventually find a crashed UFO at the bottom of the ocean:

 

Above Fort Zancudo, there's a scary noisy UFO:

 

That one also has some interesting text on it - see it up close:

 

Very high above the Hippie Camp, there's another noisy UFO:

 

Lastly, there's a noisy UFO that appears atop Mt. Chiliad at 3:00am on a rainy night, after your 100% completion:

 

All in-game UFOs can be touched EXCEPT for the one that appears atop Mt. Chiliad.  It is believed that the mountain glyphs match the mural like so:

There are other in-game mysteries too. Check out my other posts because they might have something to do with this puzzle.  One thing I stumbled on is an unrelated watch product (right) that features similar writings to the in-game alien writings (left) and so here is the cipher for it:
