Blessings in Christ,Paul,it is located in NW Saudi Arabia,on the old maps they show Midian also in NW Saudi Arabia..The  current maps have been changed.It is worth watching these videos.everything is present at the site they found.A mass graveyard believed to be for the 3000 slain after they worshipped the golden calf.some of the pillars remain that Moses erected and so much more.They show the rock that Moses probably struck etc.Also in the vicinity of Mt Sinai there is a menora etched into one of the rocks.
