31. Iron projectile point, Ngre Kataa, 2009

Description:
Iron projectile point. The head (left) is asymmetrical, perhaps the result of its base being broken. The intact side of the base is shouldered. Two small barbs protrude from opposite sides of the point's long tang (right). To make an arrow, the tang would have been inserted into a shaft made of bamboo, reed or lightweight wood. This point was found in an area (mound 6) that archaeologists interpret as a metallurgical workshop. The artifact has been corroded by rusting. Scale in cm. Length: 10.1 cm. Weight: 8.9 g.

32. Artifact cluster, Mound 6, Ngre Kataa, 2009

Description:
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.

34. Iron projectile point, Ngre Kataa, 2009

Description:
Triangular-headed iron projectile point (SF 09-033) with a slightly squared base (left ) and a short tang (right). To make an arrow (snini in Nafaanra), the tang was inserted into a straight shaft made of bamboo, reed or lightweight wood to which it was hafted. This artifact was found close to several anvil/grinding stones in an area (mound 6) that archaeologists interpret as a metallurgical workshop. The projectile point shows signs of corrosion by rusting. Scale in cm. Length: 8.1 cm. Weight: 9.3 g. Site Ngre Kataa. 30 May 2009.

35. Copper alloy (brass) bar, Ngre Kataa, 2009

Description:
A piece of a copper alloy (brass) bar, found in association with burned features that archaeologists interpret as linked to metalworking (left: side view; right, end views). The bar is square in cross-section (right). One end appears finished and has a slight circular depression or dimple (bottom right). The other end (top right) is jagged and appears to be broken from a longer bar. The artifact was recovered from soil associated with an amorphous burned feature, underneath which were a series of burned basins likely created by forging activities. The object is similar in appearance to brass bars known from the Ma'adin Ijafen cache of brass ingots documented by Theodore Monod in eastern Mauritania in the 1960s. As such, this may be the form in which metalworkers got the copper alloys that were worked at the site. Length: 1.7 cm. Weight: 2.8 g. Scale in cm. Site Ngre Kataa. 25 June 2009.

36. Burned features unit 50N 8W, Ngre Kataa, 2009

Description:
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.

37. Excavated burned basins, unit 50N 8W, Ngre Kataa, 2009

Description:
A cluster of burned basin-shaped features is exposed in the northwest corner of unit 50N 8W in an area interpreted by archaeologists as a metallurgical workshop (mound 6). The basins comprised a thin layer of fire-hardened sediment, red to dark red (Munsell colors 2.5 YR 3/6 & 4/8) in color. Basin features 1 (top right) and 2 (left of feature 1) measured about 8-9 cm deep and were filled with ashy soil. Basin feature 5 (far left) was shallower. Its fire-hardened surface showed a pinkish tinge. Samples of burned basin matrix from features 1 and 5 yielded thermoluminescence (TL) age estimates of 1500 +/- 40 CE (feature 1; Univ. Wash. 2455) and 1580 +/- 40 CE (feature 5; Univ. Wash. 2456). Photo bar marked in 5 cm increments. Arrows pointing north. Site Ngre Kataa. 29 June 2009.

38. Anvil stone in a metallurgical workshop, Ngre Kataa, 2009

Description:
A boulder used as an anvil stone (GS 09-07) sits insitu in an excavated area interpreted as a metallurgical workshop. A black-and-white photo scale stick stands vertically against it. The boulder's upper surface shows signs of use wear and its north-facing side is marked by a cup-shaped depression that resulted from repeated use. To the north (left), a fist-sized hammer stone (GS 09-09) rests insitu on a pedestal of soil left in place as the unit was excavated. Two stones showing evidence of use as grinding stones sit nearby, a north arrow placed by one(GS 09-10; center photo) and one in the southwest corner of the excavation unit (GS 09-08; bottom right). Another insitu anvil stone (GS 09-6) sits in the northeast corner of an adjacent excavation unit (48N 0W; top right of photo). The narrow band of loose soil angled across the southwest corner of the excavation was created by a burrowing animal. Photo stick and small arrow scale in 5 cm intervals. Photo scale arrows pointing north. Site Ngre Kataa. 2 June 2009.

39. Anvil stone in a metallurgical workshop, Ngre Kataa, 2009

Description:
A boulder used as an anvil stone (GS 09-01) sits insitu in an excavated area interpreted as a metallurgical workshop. This was one of several boulders associated with burned features and other residues of metalworking. The boulder's upper surface showed signs of use wear and its south-facing side is marked by a deep cup-shaped depression that resulted from repeated use. A burned feature interpreted as the remains of a forge is visible behind the anvil stone (upper left) in the northwest corner of excavation unit 50N 2W. Flat photo scale in cm. Arrow pointing north.

40. Anvil stones in a metallurgical workshop, mound 6, Ngre Kataa, 2009

Description:
Excavations uncovered three insitu boulders placed in a row that were used as anvil stones in an area interpreted as a metallurgical workshop. Multiple surfaces of the boulders show signs of wear caused by hammering and grinding. Repeated use of the anvil stone in the foreground (GS 09-03) has created a clear depression on its upper surface and its left side is flattened by wear. The middle anvil stone (GS 09-02) has multiple depressions created by use on its upper surface. The anvil in the rear of the photo (GS 09-01) shows wear on its top and side surfaces, with dirt still embedded in a deep cup-shaped depression on its south-facing side in this photo. To the east (right) of the boulder in foreground, the flat surface of a grinding stone (GS 09-04) is visible in the east wall of the excavation unit. A broken pedestal base of a pot sits on its side to the east (right) of the middle anvil stone. In the upper left corner of the photo, a burned feature interpreted by archaeologists as the remains of a forge has been exposed. The red-and-white band above the photo sign is a two meter scale, marked in 10 cm increments. View looking north across two exavation units: 50N 2W (top of photo) and 48N 2W (bottom of photo). The 2x2m units have been excavated to slightly different depths. Site Ngre Kataa. 1 June, 2009.
