Ron Wyatt has argued that rock engravings in Djebel al Lawz (Saudi Arabia) demonstrate the true location of the Mt Sinaï (using especially a shape looking like a “menorah” in the engravings). This is wrong. It is utterly simple, using simply a satellite view to show that these engravings are a primitive cartography of the main obstacles, and paths, near the rock !
I also want to thank the little blog “Against Jebel al Lawz” that brought me to research the issue more closely.
