Bayazang, Mongolia - Lightening Over The Ger by David Min Via Flickr: The Flaming Cliffs site, also known as Bayanzag, sometimes Bain-Dzak (red cliffs), is a region of the Gobi Desert in the Ömnögovi Province of Mongolia, in which important fossil finds have been made. It was given this name by American paleontologist Roy Chapman Andrews, who visited in the 1920s. The area is most famous for yielding the first discovery of dinosaur eggs. Other finds in the area include specimens of Velociraptor and eutherian mammals. It is illegal here to remove fossils without appropriate permits. The red or orange color of the sandstone cliffs (especially at a sunset), hence the nickname.
