The Char Nuur , ( Mongolian Хар нуур , Black Lake ) is located in western Mongolia , on the southeastern edge of the "Basin of the Great Lakes". It is part of a group of lakes that are located in the predominantly southeast-northwest and east-west trending tectonic depressions. Original assumptions by Russian scientists from the 1950s that the lakes were connected by a single, large paleo lake during the Holocene or Pleistocene , have now been refuted (Grunert 2009). In addition, such a connection is not conceivable simply because of the strong relief and different elevation. However, larger local lakes have been found in the region for the periods mentioned. The Char Nuur is fed by various streams from the Changai Mountains . On the other hand, the on-site precipitation would be far too low to maintain the lake level. At the moment the lake level seems to be rising, which can be proven by satellite images. Some dunes, which have probably been on dry land since the middle Holocene, are currently drowning. The Char Nuur is a resting place for migratory birds on their way through Central Asia .
