These animals play a significant part in the everyday life of Ecuadorians, as they reproduce rapidly and need a minimum of food and care to survive. They make for a high protein meal especially for populations living in high altitude. The caldera was created by a massive eruption about 3100 years ago that generated about 5 cubic kilometres (6.54 billion cubic yards) of pyroclastic flow and covered the surrounding area in volcanic ash up to 20 cm (8 inches) deep. Activity continued until 650 CE. In combination with other eruptions from nearby Imbabura, Mojanda, Cotacachi, and Cayambe, Cuicocha is responsible for the fertile soil of the Otavalo Valley.
