There are numerous passages to explore with the largest cavern being about 15m high, with the floor measuring around 12m by 18m. Unfortunately, some recent graffiti has marred the cave paintings. Controversy has erupted among experts about the interpretation of the paintings. It is interesting that both ostriches and mammoths are depicted on the walls, proving that both lived in Mongolia up to approximately 15,000 years ago.
