Palaeoenvironment and early human occupation of southernmost South America (South Patagonia, Argentina)
Pollen and archaeological records from two areas of southern Patagonia, one in the southern part of the Deseado Massif, the other south of Lago Argentino, suggest an important influence of climate on human movements into new areas. Pollen spectra record a significant dry climate throughout the regio...

Pollen and archaeological records from two areas of southern Patagonia, one in the southern part of the Deseado Massif, the other south of Lago Argentino, suggest an important influence of climate on human movements into new areas. Pollen spectra record a significant dry climate throughout the region prior to ca. 12,900 cal BP that may correlate with the Antarctic Cold Reversal (ACR) from ca. 14,500 to 12,700 cal BP. The earliest archaeological sites date the initial exploration (sensu Borrero, 1994e95) of the Deseado Massif between 13,081 and 12,141 cal BP at the time of the Northern Hemisphere Younger Dryas (YD) cold interval (ca. 12,700e11,500 cal BP), which in the Southern Hemisphere was a time of gradually increasing temperatures. When humans set foot into the Deseado Massif, vegetation was grass steppe,indicating that conditions were wetter than during the ACR.
