The Wabar site covers about 500 by 1,000 metres, and the most recent mapping shows three prominent, roughly circular craters. Five were reported by Philby in 1932, the largest of which measured 116 and 64 metres wide. Another was described by the second Zahid expedition and is 11 metres wide: this may be one of the other three originally described by Philby. They are all underlain by a hemispherical rim of "insta-Rock," so called because it was created from local sand by the impact shock wave, and all three are nearly full of sand.
