It was mentioned that Temuujin (Genghis Khan's childhood name) moved to in the Khukh Lake ( Blue Lake ) of Kar Zurkh (Black Heart) of Sengur which exists Khurelkh. Khar Zurkh is a point topped mountain with a forest in its shady side and no trees in its front slope.
The stone of Ger with a diameter of 15 meters is on the south side of this lake. It would be the ruin of the Palace where Genghis Khan was entitled as a Khan of Mongols in 1189. The land around the lake is a region as a taiga forest zone and vast depression surrounding mountain ranges.
If you are visiting Khukh lake, consider combining it with a visit to "Deluun Boldog birthplace of Genghis Khan", and "Baldan Bereeven Monastery" at the same time.
