Site in the Eastern Desert used as a quarry for amethyst beginning in the Middle Kingdom during Dynasty 11, Dynasty 12, and Dynasty 13. The site was rediscovered in 1923, first surveyed in 1939, and explored by the Egyptian archaeologist Ahmed Fakhry from 1944–1945 and in 1949, when he copied surviving inscriptions. It was again surveyed by A. I. Sadek in 1975, a British team in 1993, and a German expedition in 1993.
