Photograph of the seven pillars in the Wadi Rum Desert in Jordan, a friendly and peaceful middle Eastern nation. Wadi Rum is one of the world’s outstanding desert landscapes. It is also known as the Valley of the Moon. From Wikipedia: It is a valley cut into the sandstone and granite rock in south Jordan at 60 Km to the east of Aqaba. It is the largest wadi in Jordan. The name Rum most likely comes from an Aramaic root meaning 'high' or 'elevated'. Several Bedouin tribes inhabit Rum and the surrounding area.
