Laguna Miscanti is a salt lake in the Andes in northern Chile .
description
The Laguna Miscanti belongs to the municipality of San Pedro de Atacama in the Región de Antofagasta in the north of Chile . The lake lies at an altitude of 4140 m in the puna of the Andes at the foot of the Miscanti volcano (5622 m). It is located in the depression of a drainless water catchment area. It gets its water mainly from groundwater inflows from the surrounding mountains. Part of the water seeps into the nearby Laguna Miñiques.
As an important biotope, the lake is part of the Los Flamencos National Reserve . Flamingos and the rare species of duck Tagua Cornuda nest on its banks . Because of its scenic beauty, it is a destination for many thousands of tourists every year.
Sediment studies showed that a paleo lake formed there 22,000 years ago. This dried up under the extremely dry conditions of the last glacial maximum 18,000 years ago. A glacial lake formed 12,000 to 8,000 years ago. The climate was much more humid than today and a relatively dense vegetation could develop in the area. In the Middle Holocene , the climate was mostly extremely dry. Until about 3,600 years ago the lake was shallow and hypersaline and dried up several times. The current conditions have prevailed for about 3000 years.
The crater of the Miscanti volcano is about 6 km away from the lake.
