smerel”Explicit posuk that Ahron was buried in Har Hahor in what is now Jordan. Where in Jordan is Har Hahor is not clearly known but the MUSLIM tradition that he was buried where he is believed to by some to have been buried is over 700 years old. ”

but 700 years leaves a big gap from 3000 years ago. On what basis did they determine that its the authentic site?
