Araracuara 2


Site 2 is located near the Araracuara rapids along the middle Rio Caquetá, in the upper Amazon basin of southern Colombia (Herrera et al. 1992). It consists of about 6 ha of anthropogenic soils that average 22 cm in depth and have evidence of residential occupation, including dwelling remains and hearths, extending to a depth of 1 m below surface. Pollen cores from the site show the presence of maize beginning at the lowest levels of occupation. Two sets of radiocarbon dates suggest an early occupation dating to approximately 4645 uncal BP (see sample Grn-14987), and a later occupation dating to between about 1565 and 775 uncal BP (Herrera et al. 1992:104-107).
