Cornuke is a bit of a flake with no geological or archaeological background, but his book on finding the real Mt. Sinai was quite interesting. That time, he snuck into Saudi Arabia, so his sneaking into Iran would not be a surprise. I'll withhold judgment until seeing what he has found.
Actually, he's a neat guy. A real showman in the classic throwback sense. Former cop, compelling speaker. Books: In Search of the Lost Ark of the Covenant; In Search of The Mountain of God (his best); In Search of the Lost Mountains of Noah. (Full disclosure: he's a friend of mine.) He's genuinely driven to follow Scriptural clues, and his presentations center on the literal reliability of the Bible. I agree with him that often scholars and experts lose sight of the plain meaning of the text.
