The Ubari Lakes are a group of about 20 lakes, set amidst magnificent sand dunes and palm fringed oases in the Fezzan region of southwestern Libya. The lakes were once one big lake but climate change caused the region, a part of Sahara, to gradually dry up between 3,000 to 5,000 years ago. The water is super-saturated with salts and carbonates, as lakes are being continuously evaporated and have no rivers replenishing them.
