Chaxa Lagoon
Atacama
Chaxa Lagoon is a shallow, high-altitude saltwater lagoon located within the Salar de Atacama salt flat in northern Chile. It lies about 7 kilometers from Toconao and roughly 50 kilometers from San Pedro de Atacama, inside the Los Flamencos National Reserve. The lagoon is notable for its mud strata and shallow waters that create ideal conditions for microinvertebrates, which form the primary diet of the flamingos inhabiting the area. It is considered one of the best places in Chile for flamingo observation, hosting three species: the Andean flamingo, Chilean flamingo, and James's flamingo. The lagoon connects hydrologically to nearby Barros Negros Lagoon through the Burro Muerto channel, enabling ecological exchange. The surrounding environment is characterized by sparse desert vegetation and significant temperature fluctuations between day and night, typical of the Central Andean dry puna ecoregion. Besides flamingos, local fauna includes species such as the culpeo fox, tuco-tuco rodents, and endemic reptiles adapted to the harsh conditions of the salt flat. Chaxa Lagoon is part of a Ramsar-protected wetland system, emphasizing its ecological importance and the conservation efforts underway to protect its unique biodiversity.

Histoire
Chaxa Lagoon lies within the Los Flamencos National Reserve, established to protect the unique wetland ecosystems of the Atacama salt flats.
Historically, this area was part of a larger lake system that has since evaporated, leaving behind extensive salt flats and shallow lagoons.
The lagoon and surrounding wetlands have long supported flamingo populations, which have been a focus of conservation efforts since the late 20th century.
The designation of the area as a Ramsar site highlights its international importance as a wetland habitat.
Over time, the lagoon's hydrology has been influenced by natural and human factors, but it remains a vital refuge for several vulnerable and endangered species.
