Tsingy de Bemaraha is a Unesco World Heritage site situated in Melaky Region, Madagascar. Most popular for The Tsingy - sharp limestone pinnacles that could reach 150 feet tall. The Tsingys actually are karstic plateaus wherein groundwater has undercut the elevated uplands, and fissures into the limestone and due to local environment, the corrosion is patterned vertically as well as horizontally. In several regions the superposition of vertical and horizontal corrosion forms has generated dramatic "forests" of limestone needles.

Pamukkale, which means "cotton castle" in Turkish, is a natural spot in Denizli Province in southwestern Turkey. Pamukkale's terraces are made of travertine, a sedimentary rock deposited by water from the hot springs. The travertines have a concentric presence as they are almost pure white presenting the location an ethereal appearance. The hot springs precipitate calcium carbonate at their mouths and create the extraordinary structures. This geological wonder is also the site of the ancient city of Hierapolis.

Salar Uyuni is the world's largest salt flat at 10,582 square kilometers, situated in southwest Bolivia, near the crest of the Andes which is at an altitude of 3,656 meters (11,995 ft) above sea level. Salar Uyuni was formed as a result of alterations between some prehistoric lakes. It is covered by a few meters of salt crust, which has a terrific flatness with the average altitude variations within one meter over the whole area. Once the rains sweep down onto the Uyuni Salt Flats, the entire expanse turns into a tremendous reflecting pool. The water on the salt flats actually hardly ever reaches up to a depth of more than 6 inches, so it provides visitors the sensational experience of strolling on the surface of a mirror.

The mountains themselves were engraved by glaciers during the Quaternary and plants on the range is thickest below 1.100 meters, with trees growing up to the treeline at 1.800 meters. Mount Huangshan features numerous striking peaks, forests of stone pillars and evergreen sturdy pines.
