There is a type-sites named Doogiin Khananii Buuts and Iher Khanangiin Buuts of Baga Berkh mountain which locates in the north, 25 km far from Bayan-Uul soum. The back rock walls of these type-sites are abundant in images and descriptions which associate with bronze and iron-age weaponry. Cow, deer, argali, ibex, wolf, leopard, camel are depicted in different motions. Horn of deer with many branches is depicted raising it and towards the back and horn of argali is depicted with 6-7 circles. When describing starting from a man riding a reindeer, camel-riding hunters hunting down the carcass games like ibex and stag until a group of walking hunters, the description did not miss the realism having shooting at the hind legs and heads of stags. These images left in Ikh Berkh and Baga Berkh mountains cover many ages of human history, contents and descriptions and they are considered as the valuable souvenirs of Mongolian rock piercing art.
