The "Rock at Horeb" in the extreme north-western part of Saudi Arabia... AND The Blackened Peak of the REAL Mount Sinai... Moses and the Children of Israel first encamped before reaching Mt. Sinai. It was here that Moses struck the rock, above, which gushed forth large quantities of water. The giant 60 foot rock is on a 300 foot tall hill, and has obvious signs of water erosion, yet it is located in this desert region. The fissure in the rock is so large that you can walk easily through it. A square 20 foot altar is also at this site, which was built after the Children of Israel defeated the Amalakites. The Amalakite territory covered "south of Judah and probably extended into northern Arabia" Britanica.
