This is one of the largest caves in Mongolia, with a main chamber at least eighty-five feet high. A rock fall in 1995 blocked off one long extension in the cave, but several smaller galleries leading off from the main chamber still remain. It was reportedly inhabited by Stone Age people during the Upper Paleolithic, 10,000 to 40,000 years old. The cave is famous for its rock paintings, which have been dated to 17,000–22,000 years ago. Done with light pink and red-brown ochre pigments, the paintings depict Paleolithic fauna such as mammoths and ostriches which are no longer found in the area, as well as camels, ibex, deer, and other more familiar animals. Unfortunately many of the drawings have now been defaced or covered with dust and are no longer visible.

The paintings have been discovered in 1972 and include some amazing drawings of animals that no longer are found in Mongolia such as mammoths, elephants and ostriches.
