Test Pit 3 was excavated adjacent to an area on Level 5 (field stone) and reveals the Level 6 (river stones) on the right. Level 6 was more than 1 meter thick and covered the entire mound. The square seen in the background was the area opened on the central pit that ultimately descended through level 6. The pit that was excavated was labeled level 7. American volunteers are seen excavating on the right side of the central pit in Test Pit 4.
