Elsen tasarkhai is a
part of the Mongol Els sand dunes, which stretch from the Tuv, Uvurkhangai, and
Bulgan provinces all the way west to become part of the Khugnu Khan mountain
range. The sand dunes are 80 km long total. Dividing the southern part of the
sand dunes with the so-called northern Mongolian sand, Khugnu Tarna is a main
road. River Tarnat flows in the western part of the sand dunes, it is sodden
under its surfaces, so shrubberies such as willow, elm, dogwood, shrubbery grow there.
In the north there is the rocky and woody mountain
“Khugnu khaan”. in the south lies Ikh Mongol which defines the central point of
Mongolia and is surrounded by the Elsen tasarkhai.
The widest section of the sand dune is located in
the Ikh Mongol mountain area and covers an area of 9-10 km2. Half of
the Ikh Mongol sand is covered by plants, so its mostly not loose sand.
