Comechingón
Comechingón (plural Comechingones) is the common name for a group of people indigenous to the Argentine provinces of Córdoba and San Luis. They were thoroughly displaced or exterminated by the Spanish conquistadores by the end of the 17th Century.
The two main Comechingón groups called themselves Henia (in the north) and Kamiare (in the south), each subdivided into a dozen or so tribes. The name comechingón is a deformation of the pejorative term kamichingan—"cave dwellers"—used by the Sanavirón tribe.
They were sedentary, practiced agriculture yet gathered wild fruits, and raised animals for wool, meat and eggs. Their culture was heavily influenced by that of the Andes.
Several aspects seem to differentiate the Henia-Kamiare from inhabitants of nearby areas. They had a rather Caucasian appearance, with beards and supposedly a minority with greenish eyes. Another distinctive aspect was their communal stone houses, half buried in the ground to endure the cold, wind and snow of the winter.
