Ancient Map of Tiwanaku Found Hidden in Plain Sight

I'm theorizing that this may be a map of the ancient site of Tiwanaku, Bolivia. The map is engraved or carved in to the cylindrical rock that's located in between the sub-terranean pit area and the main temple complex. This is an UNESCO site and has a lot of strange and unique structures. Although, there was something left behind to give us a clue of the ancient past. This engraving or carving is either a petroglyph, a random work of art, or, an ancient map of the ancient temple of Tiwanaku carved into the stone which has been hidden in plain sight this whole time.

What do you think this is?
