Archaeology
Qillqatani is the first archaeological site in the Lake Titicaca basin to be systematically excavated. Archaeologists have identified 36 cultural strata at the site. From 7500 to 4000 BP, Qillqatani was inhabited by hunter-gatherers as a seasonal campsite. These early occupants hunted mostly camelids, and some deer. From 3660 BP onwards, Qillqatani was inhabited by pastoralist camelid-herders who built houses and began to occupy the site long-term. These later occupants also began to trade with people from lower attitudes to obtain Chenopodium.
