A small round stone (GS 08-11) rests insitu next to an irregularly shaped area of burned fire-hardened sediment in an area (mound 6) that archaeologists interpret as a metallurgical workshop. The stone has wear consistent with use as a hammerstone. The burned sediment was next to a circular area of soil that showed signs of oxidation through exposure to high heat. A small piece of copper alloy metal lies at the edge of the fire-hardened sediment, to the left of the hammerstone and above the right site of the photo stick. The feature is likely associated with forging activities. Photo scale at bottom marked in 5 cm intervals. View from above, north at top of photo. Site Ngre Kataa. 5 July 2008.
