Middle archaic period domestic architecture from southern peru.

Domestic or residential structures ranging in age from 6040 to 6850 years old have discovered at the open air site of Asana in the high sierra of southern Peru. These are the earliest domestic structures known from the high elevation zones of the south central Andes, and they are contemporaneous with sites with structures on the north Chilean littoral. Analysis of site structure and content suggests that during the Middle Archaic the site was a logistical camp within a dry puna-high sierra settlement system.
