Crescent Moon Spring with its lush vegetation sustained by spring water and deep blue Crescent Lake is a true miniature oasis in a desert.
Crescent Spring lies at the foot of the Singing Sand (Mingsha) Mountains, which are smooth pale-golden dunes, and is named for its shape. It is about 100m long and 25m wide, and has fish and water weeds that are said to be good for the health.
The area is often hit by sandstorms, which shut out the sunlight. Interestingly, however, for hundreds of years people have never seen the spring filled up with or covered by sand.
The Crescent Moon Spring is one of the seven great endangered attractions in china, check out other six.
