Salar del Huasco

Salar del Huasco is a salt flat dotted with ponds and salt marshes, and seasonally partially covered with water, in northern Chile. It is part of Ramsar Site 874, and was, for several years, a national park. The area has a significant population of flamingos.

The salt flat is probably bordered by a fault on its western side, and a river delta forms much of its northern edge; it is now crisscrossed by stream channels. In the Pleistocene the salt flat was covered by a lake that was identified through its clay and diatomite sediments and which has left well preserved shorelines and terraces.
