An iron artifact (SF 09-031) recovered from screened soil taken from the southern end of excavation unit 50N 2W where two large boulders used as anvil/grinding stones were located. In the unit' s northwest corner was a burned feature interpreted as the remains of a forge in an area where metalworking took place. The flat iron object is pointed on one end and has two rounded lobes at the other, perhaps to facilitate turning (like a key?). Its function is unknown. The object has been corroded by rusting. Scale in cm. Length: 5.7 cm. Weight: 9.3 g. Site Ngre Kataa. 30 May 2009.
