11. In situ grinding stones and pottery, unit 44N 4W, Mound 6, Ngre Kataa, 2008

Description:
Several grinding stones, a whole pot and a cluster of pottery sherds have been exposed in situ at the base of level 3, unit 44N 4W at Mound 6, Ngre Kataa. The large grinding stone in the foreground (grinding stone 1, NK-08-112) is oriented with its grinding surface facing down. Another smaller stone rests on a soil pedestal created as archaeologists excavated surrounding soil to a lower level. Upper right, a whole pottery jar (NK-08-176) sits next to a large grinding stone (grinding stone 3, NK-08-173) oriented with its grinding surface up. To the far left, above the photo scale in centimeters, archaeologists have exposed the edges of a pottery jar, broken in half and lying on its side. As excavations extended into the adjacent unit (42N 4W, to the left), this broken pot was found to be associated with two tuyere fragments. This cluster of grindstones, tuyeres and nearby burned features is interpreted as part of a larger metal-working workshop, the activities of which led to the build up of mound 6. The soil on the right side of the unit is darker because it is moister than that on the left. View to west. Site Ngre Kataa. 1 July, 2008.

12. In situ pottery and grinding stones, unit 42N 4W, Ngre Kataa, 2008

Description:
Excavations in unit 42N 4W have exposed clusters of pottery, grinding stones, tuyeres and an area of burned soil associated with metal working at Mound 6, Ngre Kataa. Foreground, left, a grinding stone (GS 08-10) rests with its working surface face down. It sits at a slightly higher level than a nearby (left) whole pottery jar (NK 08-406). To the right of these, a partial pot (NK 08-282) and a tuyere fragment (NK 08-284) are clustered together with two halves of a broken pottery jar, lying with its exterior surface facing down. To the south (behind), near the sign board and framed by photo scales, is a burned feature. Next to it sits a hand-held hammerstone (GS 08-11). Another partial pottery jar (NK 08-520) and a small flat grinding stone (GS 08-12) have been exposed to the left of the sign board at 77 cm below the unit's datum. The narrow dark bands visible in the soil are the traces of animal burrows. Photo scale adjacent to the sign board in centimeters. View looking south. Site Ngre Kataa. 7 July 2008.

13. 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.

14. 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.

15. 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.

16. 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.

17. 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.

18. 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.

20. 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.
