Salinas is a lake event in the Salar de Uyuni, Bolivia.

The existence of this lake event is documented by tufa mounds which are up to 7 metres (23 ft) high.[1] It belongs to a series of ancient lakes which covered the southern Altiplano in Bolivia, reaching a maximum surface area of 33,000–60,000 square kilometres (13,000–23,000 sq mi). This series includes several phases, two major phases named Lake Tauca and Ouki as well as a few minor ones. These lake phases appear to occur in response to increased moisture supply from the Amazon.[2] The formation of the Salinas lake was probably accompanied by a 50-100% increase of precipitation.[3]

The Salinas event lasted between approximately 95,000 and 80,000 years ago. It was preceded by another lake event,

Llano de Chajnantor.[7]

During the Salinas lake cycle, lake levels did not rise above 3,670 metres (12,040 ft) altitude,

Salar de Coipasa/Salar de Uyuni basin, as in the previous Ouki phase.[10] This input probably did not exceed 45% of the total water supply of the Salinas lake.[11]
