Interesting comments.
But some discrepancies with Exodus:
1. Exodus 14. Then the Lord said to Moses, tell the Israelites to turn back and camp by Pi Hahiroth ...
Pi Hahiroth is understood. It is the place where the Egyptian king kept his royal barges. These barges (or boats) sailed on the Gulf of Suez, because that is the closest body of water to the king's palace. Hence there is no doubt about where Pi Hahiroth was located, and the logic is strong. Exodus states that the Red Sea crossing took place there. My opinion - at the northern end of the Gulf of Suez. with the Hebrews crossing exposed seabed (at a location at the northern end of the Gulf of Suez), probably where the sea water was 10-20 feet deep (normally), but the water was drained by the exceptional events that took place when Moses spoke to the Lord.
Hence I don't think that the sea crossing took place on the Gulf of Aqaba. And if you consider that option, you would need to explain how the Pharoah's chariots chased the fleeing Hebrews all the way down the west side of the Sinai. That would be an enormous undertaking.
Also, the point that you chose as the crossing on the Gulf of Aqaba has a sea crossing of about 10 miles. That would take the Hebrews about 5 hours to do, assuming they were walking across wet (sloppy sand). That seems far too long to me. The Bible indicates that the Egyptians were close by and hot on their heels. Hence to me, the crossing at Pi Hahiroth makes more sense, probably a distance something like 0.8-1 mile, taking the Hebrews about 20-30 mins to cross. Which seems logical - that the ocean would flow back into the Gulf and drown the Egyptians after about 30 minutes (after all the Hebrews escaped to the opposite coast).
But I encourage diverse thinking, and the pictures that you showed of the mountain in Midian are interesting.
