The Chavín culture is an extinct, pre-Columbian civilization, developed in the northern Andean highlands of Peru around 1000 BCE. It extended its influence to other civilizations along the Peruvian 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. In the periodization of pre-Columbian Peru, the Chavín is the main culture of the Early Horizon period in highland Peru, characterized by the intensification of the religious cult, the appearance of ceramics closely related to the ceremonial centers, the improvement of agricultural techniques and the development of metallurgy and textiles. The best-known archaeological site for the Chavín culture is Chavín de Huántar, located in the Andean highlands of the present-day Ancash Region. Although Chavín de Huántar may or may not have been the center or birthplace of the Chavín culture, it was of great importance. It has been designated a UNESCO World Heritage Site. Achievements The chief example of architecture is the Chavín de Huántar temple. The temple's design shows complex innovation to adapt to the highland environments of Peru. To avoid the temple's being flooded and destroyed during the rainy season, the Chavín people created a successful drainage system. Several canals built under the temple acted as drainage. The Chavín people also showed advanced acoustic understanding. During the rainy season water rushes through the canals and creates a roaring sound that emulates a jaguar, a sacred animal. The temple was built of white granite and black limestone, neither of which is found near the Chavín site. This meant that leaders organized many workers to bring the special materials from far away rather than use local rock deposits. They also may have been traded from different civilizations in the area. The Chavín culture also demonstrated advanced skills and knowledge in metallurgy, soldering, and temperature control. They used early techniques to develop refined gold work. The melting of metal had been discovered at this point and was used as a solder. The people domesticated camelids such as llamas. Camelids were used for pack animals, for fiber, and for meat. They produced ch'arki, or llama jerky. This product was commonly traded by camelid herders and was the main economic resource for the Chavín people. The Chavín people also successfully cultivated several crops, including potatoes, quinoa,
