About Bayanzag (Flaming Cliffs)
It is a Neolithic site where the large dinosaur skeletons on show in the Ulaanbaatar Natural History Museum were found. In the west it is better known as the Flaming Cliffs, so named by explorer Roy Chapman Andrews. In the same are he also discovered petrified forests, remains of mammals, and in particular the skeleton of a hornless rhinoceros, the largest known mammal in the world. Bayanzag is in Bulgan sum in a desert zone that as its name suggests, is strewn with saxaul bushes.
Rent a 4wd or just buy a trip, and go. In the desert there's no road. The driver knows where you have to go. :o)
