Salinas Grandes (Jujuy)
Jujuy
Salinas Grandes is an extensive salt flat located in the provinces of Jujuy and Salta in northwest Argentina, covering an area of approximately 212 square kilometers at an average altitude of 3,450 meters above sea level. This vast white desert is notable for its bright, reflective salt crust, averaging about 30 centimeters thick, which creates stunning panoramic vistas. The salt flat is part of an endorheic basin that extends northward to the highly saline and alkaline Guayatayoc lagoon. The region holds industrial significance due to its rich deposits of sodium, potassium, and lithium brine beneath the salt surface. The lithium reserves are currently under exploration, with development rights allocated to LSC Lithium. However, this exploitation has raised concerns among Indigenous communities regarding groundwater depletion and land rights. Geologically, Salinas Grandes formed between 5 and 10 million years ago through the gradual evaporation of volcanic salt-rich waters in the basin. Its unique landscape attracts visitors seeking natural beauty and cultural insights into the Puna region.

Historia
Salinas Grandes originated between 5 and 10 million years ago as a result of volcanic activity depositing salts into an endorheic basin.
Over time, the evaporation of these salt-rich waters formed the extensive salt crust seen today.
Historically, the salt flats have been a source of sodium and potassium minerals, with modern interest expanding to lithium extraction.
Indigenous communities have long inhabited the region, and recent industrial developments have sparked debates over environmental impacts and land rights.
