A tri-looped iron bangle (SF 09-158) and a flat iron disc (SF 09-159) exposed insitu between two stones. The surfaces of the stones showed signs of use for grinding. This group of objects (cluster D) was found near--and may have been part of--a larger cluster of objects (A-D) that archaeologists interpret as a shrine placed over stratified deposits in a metallurgical workshop. Photo scale marked in 5 cm intervals. Arrow pointing north. Site Ngre Kataa. 9 June 2009.
