Mount Hor is perhaps Mizpe Zohar (Arabic ez Zuwera) ? The way of Atharim is perhaps the track to Mezad Hatrurim from Mispe Zohar ? Ancient Arad is 10 kilometers/6 miles west of Mispe Zohar (for map of 1:250,000 scale cf. Bazak Guide to Israel 1979-1980. Jerusalem. Bazak Israel Guide Book Publishers, Ltd.)
