Ringing Mountain of Sand (Singing Sand Mountains) Mingshashan

At the foot of Mingshashan lies the 200m/656ft long Lake of the Crescent Moon (Yueyaquan), which gets its name from its crescent-like shape. The formation of the lake resulted from a geological peculiarity - the north and south slopes are higher than the east and west - and from the wind which blows from west to east. The wind initially blows in a southeasterly direction, and is then forced upwards where it rotates spirally before finally retreating in an easterly direction. As a result, the lake has never once become silted up with sand in 1000 years.
