In Queros, a Peruvian village east of the ancient Inca 
capital of Cuzco, Quechua-speaking Indians preserve a traditional 
style of life adapted to high altitudes. Like their rural 
counterparts in Nuhoa, a district south of Cuzco that has been 
intensively studied by physical anthropologists, these Indians 
herd llamas as a major means of subsistence. The piled stone 
houses protect the residents from rain and wind but provide 
only moderate protection from low nighttime temperatures 
during the cold, dry season.
