The Unsolvable

This is Rio, and Wilson in one of the most complicated MYST puzzles I have stumbled across in my life. This puzzle held me in my MYST career for ten years.

on another note, Cyan, in the "CYAN was here" belongs to

The reason for all the posters and drawing on the wall, is that, the puzzle was severly complicated and people would have sent a good amount of time going over it, getting bored and inscribing things.
It would also make a great place for advertisements! 8D
