Base of excavation level 21, unit 68E 4N, Mound 129 at Kuulo Kataa. Visible in the walls of the 1 x 2 m unit are its distinct soil layers. Dark upper levels contained many rootlets. These soils transition to a lighter brown zone below, which in turn shows a distinct boundary with ash-filled gray levels beneath. Three radiocarbon dates associated with the gray ashy levels fall in the calibrated age range from c. 1400 to 1530 CE. Equally distinct is the boundary below the ashy layers, where lighter brown soils of lower levels can be seen in plan view at the base of the unit. Several features are visible against these lighter-colored soils. Center photo is an irregularly shaped patch of laterite which archaeologists interpreted as a remnant floor. At upper and lower right, concentrations of charcoal stand out against surrounding light soil. Mound 129 covers roughly 750 m2 and rises roughly 2 meters above the surrounding ground surface. Its stratigraphy suggests a complex history of formation through both primary occupation (living surfaces) and refuse dumping (midden deposits). Kuulo Kataa, 17 June, 2000.
