Khetsuu Khad:
In the eastern part of Khyargas Lake, there are high cliffs up to 20meters on the shore of the lake, and underwater of the lake, its cliff is 5-7 kilometers long. The rocky area is called Khetsuu Khad due to its difficulty walking on that scatted rock on the shore of the lake. Thus it’s called Khetsuu, which means “difficult or hard” in Mongolia.
