Natural arch in Wadi Rum, Jordan
People have lived in the Wadi Rum area of southwestern Jordan for thousands of years, but it wasn't until 1998 that the Jordanian government placed the area's fragile desert habitat under the protection of the Aqaba Special Economic Zone Authority. Several natural arches can be found in Wadi Rum, one of which was pictured in our May mystery photo. Located about 200 yards from the famous Rock Bridge of Kharaz, the arch shown is about 85 feet long.
