Description
A synthesis of archaeological research developed in Chonos Archipelago, Chile, is presented (43°50’-46°50’S). Results indicate that marine hunter-gatherer sites located in modern day coastlines are commonly eroded by sea tide and ages not older than 1107 years cal. BC. Background information of an older site led to a methodological survey approach for earlier evidence in the northern portion of Archipelago of Guaitecas. This archaeological site GUA-010 was re-evaluated, confirming its chronology of 4313 years cal. BC and its preservation in a higher terrace even with the frequent vertical tectonic movements in the area (43°50’S). The implications of this type of record for reconstructing and explaining initial human occupation of this archipelagic territory are discussed, including maritime adaptation process at the southernmost end of South America.
