Location of the project area in the eastern NGotto Forest Reserve, southern Central African Republic.
Archaeological site locations (labeled) are marked with black dots/ovals and the location of the sediment core (FC400) is marked with an open circle.

East wall excavation profile in the BB01 slag mound.
This profile illustrates the structure typical of most excavated mounds. Radiocarbon dates (cal mid): 1) AD 1795; 2) AD 1795; 3) AD 1804 (see Table 2).
