Would that be in the northwest corner of Saudi Arabia where the true Mount Sinai (I know it's probably misspelled. The mountain where Moses was briefed by God) is located?
If you want to learn about that place, then find and read the book, The Gold of Exodus, by Howard Blum. It includes photographs of the site. Blum and an associate / bodyguard travelled the route of the exodus as described in the KJV Bible. They found ALL of the waypoints written of in the Book and sneaked into Saudi and discovered the site at the base of the mountain where Arin's alter still exists. The Saudis have built a top secret military site on the mountain and has the whole area fenced. Could all of this be part of the Shriner's' secrets?
Blum was on a treasure hunt for the gold that Moses had the Israelites throw into a dried riverbed after he came back down and saw the idol they'd made. The book tells how he'd came onto the story.
