The Chavín culture is an extinct, pre-Columbian civilization, named for Chavín de Huantar, the principal archaeological site at which its artifacts have been found. The culture developed in the northern Andean highlands of Peru from 900 BCE to 200 BCE. It extended its influence to other civilizations along the coast. The Chavín people (whose name for themselves is unknown) were located in the Mosna Valley where the Mosna and Huachecsa rivers merge. This area is above sea level and encompasses the "quechua", "suni", and "puna" life zones.
