A cluster of burned features is exposed in the northwest corner of excavation unit 50N 8W in an area interpreted by archaeologists as a metallurgical workshop (mound 6). Along the unit's west wall (left in photo) is an amorphous zone of fire-hardened red (Munsell color 2.5YR 3/6) matrix. A piece of brass bar (SF NK 09-293) was found in soil associated with this burned feature. Above and to the right (northeast), two circular burned features are visible in outline. These basin-shaped features had a thin lining of fire-hardened sediment, red to dark red (Munsell 2.5 YR 3/6 & 4/8) in color. The basins were filled with loose ashy sediment and small pieces of charcoal. A sample of burned matrix from feature 1 (top right basin) yielded a thermoluminescence (TL) age estimate of 1500 +/- 40 CE (Univ. Wash. 2455). Further excavation revealed additional basin-shaped features beneath the amorphous burned feature. The excavation unit's northwest corner peg is visible, upper left. View looking north. Site Ngre Kataa. 27 June 2009.
