Ancón (PV45-2)


Ancón (PV45-2), also called the Tank Site, has been tested and excavated by many archaeologists during the past century, starting with Max Uhle and including Jorge C. Muelle, Thomas Patterson, and Michael Moseley (Lanning 1963:369; Patterson and Moseley 1968; Moseley 1975:28-29). It is part of an enormous occupation spanning the south side of Ancón Bay, located approximately 33 km north of Lima. The principal archaeological deposits at the site span the Late Preceramic to the Early Horizon. Probing the Preceramic occupations, Moseley found that the deposits were up to 4 m deep in spots. Many parts of the site are even deeper, particularly where covered by extensive Initial Period and Early Horizon deposits. During Patterson's 1967 excavations in these deposits, well-preserved maize cobs were recovered, three of which, listed below, were recently submitted for AMS dating, morphological analysis and DNA testing (Benz and Blake 2011).
