11. Excavation units at Mound 148, Kuulo Kataa, 2000
- Description:
- In-progress excavations of adjacent 2 x 2 m units at Mound 148, Kuulo Kataa. The base of units 70E 48-52N and 72E 50N have been excavated to depths ranging from 90-110 cm below datum. The large area of dark soil concentrated in unit 70E 50N (center) is intrusive pit fill which cut through the living surface at this mound level. An area of packed reddish-orange laterite gravel in unit 70E 52N (bottom, left) likely represents a prepared floor surface. To the right of the dark pit soil, in the boundary between units 70E 50N and 70E 48N, is a an irregularly shaped burned feature interpreted by archaeologists as likely associated with metalworking. Two radiocarbon samples associated with this burned feature had calibrated age ranges between c.1200-1400 CE. A cluster of hearth stones has been exposed in nearby unit 72E 50N (center photo). White bags filled with soil samples collected for flotation sit outside the excavated area together with excavation equipment. View looking eastwards. Kuulo Kataa, 11 July, 2000.

12. North wall, unit 46N 2W, Mound 6, Ngre Kataa, 2009
- Description:
- The mouth of a perforated shrine pot (left) is covered with the pedestaled base of another pot. It remains in situ as the surrounding areas of unit 46N 2W are excavated to lower levels. Behind, the stratified layers of Mound 6 are visible in the unit's north wall. Center (back) are a series of anvil and grinding stones exposed at higher mound levels in other excavation units. During excavations in 2008, a cluster of four anvil/grinding stones was found at a level slightly higher than but adjacent (left/west) to the perforated pot. At right, in lower levels, two grinding stones rest at an angle in association with a burned feature. Archaeologists interpret Mound 6 as a metallurgical workshop at which stratified levels built up through repeated use of the same location. Photo scale in centimeters. Site Ngre Kataa. 2 July, 2009.

13. Grinding stone, Mound 6, Ngre Kataa, 2008
- Description:
- A deeply worn grinding stone (grindstone 1, NK-08-112) removed from levels 1-2, unit 44N 4W, Mound 6, Ngre Kataa, photographed at the side of the excavation unit. The grinding stone was found in association with other grinding stones, tuyere fragments and whole and partial pots. When found, the grinding stone was oriented with its working surface facing downward. It was located adjacent to a concentration of dark soil (feature 1) that contained abundant oxidized sediment, slag and broken pottery. Archaeologists interpret the features at Mound 6 as facilities used to make and process metals. Photo scale in 5 centimeter increments. Ngre Kataa, 2 July, 2008.

14. Perforated pottery jar, Mound 6, Ngre Kataa, 2009
- Description:
- A perforated pottery jar lidded with the pedestaled base of another pot sits in situ at the base of level 6, unit 46N 2W at Mound 6. The pot contained eight cowries and is interpreted by archaeologists as a shrine pot placed in association with metalworking facilities. Photo scale in 5 cm increments.

15. Drawing a plan map, Mound 6, Ngre Kataa, 2008
- Description:
- Banda Research Project team members Amanda Logan (right) and Amy Groleau (left) draw a plan map of units 44N 4W and 44N 6W, Mound 6, Ngre Kataa. They map in situ artifacts and features, including several large grinding stones, a whole pot, pottery clusters and a tuyere fragment. Wooden stakes mark the corners of 2 x 2 meter excavation units. A photo scale place near a partially exposed everted rim jar in unit 44N 6W (NK-08-407) is in 5 centimeter increments. Ngre Kataa, 7 July, 2008.

16. Large slag nodule, Ngre Kataa, Mound 8, 2008
- Description:
- Iron slag is formed as a byproduct of iron smelting. Here a large slag nodule has broken in half, revealing its interior texture. At the archaeological site of Ngre Kataa, large chunks of 'bubbly' slag like this were occasionally found in household and other contexts, away from areas otherwise associated with metal-working activities. Potters at the time of the site's occupation had begun to use crushed iron slag as a tempering agent in their potting clays, which may explain why large nodules were being carried and cached in areas away from metal-working locations.

17. Burned features, unit 46N 2W, Ngre Kataa, 2009
- Description:
- Three burned features are visible at the base of level 6 in unit 46N 2W. Two circular features (F1, right & F2, left) have been cross-sectioned, creating a straight edge. Burned feature 3 is an irregularly shaped (rectangular) area pedestaled on the east (right) side of the excavation unit. Along the unit's west wall (left) is an unexcavated rectangular area. Within this matrix was a perforated pot (NK 09-789) lidded with the pedestal base from another pot. The perforated pot contained cowries and small fragments of iron. In units to the north (behind), a row of insitu anvil stones (GS 09-03, -09-02 and 09-01, near to far) is visible in units 48N 2W and 50N 2W. To the east (right) of these, a flat grinding stone (GS 09-08) and an anvil stone (GS 09-06) can be seen insitu in units 48N 0W and 50N 0W. A pottery jar (NK 09-790) rests insitu in the center of unit 50N 0W. To the left of the archaeologist in the blue shirt (Abass Iddrisu), a flat grinding stone (GS 09-12) and a pot (NK 09-685) lidded with a grinding stone (GS 09-13) are visible on the boundary between units 50N 4-6W. Excavation units measure 2 x 2 meters. Site Ngre Kataa. 24 June 2009.

18. 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.

19. 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.

20. Burned feature, unit 46N 2W, Ngre Kataa, 2009
- Description:
- Two views of a burned basin-shaped feature (Feature 2) in mound 6, unit 46N 2W, part of an area that archaeologists interpret as a metallurgical workshop. The feature has been sectioned to reveal its profile. Viewed from the top, the circular feature consists of a ring of fire-hardened yellowish red (Munsell color 5YR 5/8) sediment. The fire-hardened matrix is thicker at its top edge than it is at the bottom of the basin, where its color is dark red (Munsell 2.5YR 3.6). In profile view (second photo), the basin appears as a narrow band of yellowish red fire-hardened sediment. The fire-hardened sediment is thin and rounded at the base of the basin, suggesting that it may have formed around a round-based vessel used to heat metals. A thermoluminescence sample of the burned matrix yielded a date of 1490 +/- 50 years (Univ. Wash. 2364). Photo scale in cm. Site Ngre Kataa. 23 June 2009.
