The presence of iron fragments at the site also pointed to a meteorite impact, as there are no iron deposits in the region. The iron was in the form of buried fist-sized cracked balls and smooth, sand-blasted fragments found on the surface. The largest fragment was recovered in a 1966 visit to Wabar and weighs 2.2 tonnes. It is known as the "Camel's Hump" and was on display at the King Saud University in Riyadh until it was moved to the new National Museum of Saudi Arabia in Riyadh, where it is displayed in the entrance foyer.
