Split Apple Rock, New Zealand

Split Apple Rock is a geological rock formation in The Tasman Bay off the northern coast of the South Island of New Zealand.

Stone Forest, China

The Stone Forest or Shilin (Chinese: 石林; pinyin: Shílín) is a notable set of limestone formations located in Shilin Yi Autonomous County, Yunnan Province, People's Republic of China, near Shilin approximately 120 km (75 mi) from the provincial capital Kunming.

Moeraki Boulders, New Zealand

The Moeraki Boulders are unusually large and spherical boulders lying along a stretch of Koekohe Beach on the wave cut Otago coast of New Zealand between Moeraki and Hampden. They occur scattered either as isolated or clusters of boulders within a stretch of beach where they have been protected in a scientific reserve. The erosion by wave action of mudstone, comprising local bedrock and landslides, frequently exposes embedded isolated boulders. These boulders are grey-colored septarian concretions, which have been exhumed from the mudstone enclosing them and concentrated on the beach by coastal erosion.

Great Blue Hole

The Great Blue Hole is a large submarine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 70 km (43 mi) from the mainland and Belize City.

Giant's Couseway

Flanked by the wild North Atlantic Ocean on one side and a landscape of dramatic cliffs on the other, for centuries the Giant’s Causeway has inspired artists, stirred scientific debate and captured the imagination of all who see it.

Inquiring minds have marvelled at the regularity of the stones’ shape and the vastness of their number. Science, of course, holds the answers to most of these questions but in the days before scientists there were storytellers.

Storytellers have their own explanation for this captivating stretch of coast, and many stories endure to the present day. The most famous legend associated with the Giant’s Causeway is that of Irish giant, Finn McCool. It was imagined that the causeway is the remains of the bridge that Finn built linking Ireland to Scotland. The landscape became so imbued with the spirit of this legend that it gave rise to the name – the Giant’s Causeway.

Death Valley, USA

One of the mysteries of nature is the phenomenon known as the Racetrak Death Valley in California. Absolutely dry on a surface perfectly flat stones move without any human or animal to step on them. The stones move and leave behind a trail in the mud dry. Never been filmed this phenomenon, but the stones change their positions every few years when "plmiba" several times through the arid valley.

Mono Lake, California

Mono Lake is a large, shallow saline soda lake in Mono County, California, formed at least 760,000 years ago as a terminal lake in a basin that has no outlet to the ocean. The lack of an outlet causes high levels of salts to accumulate in the lake. These salts also make the lake water alkaline.

This desert lake has an unusually productive ecosystem based on brine shrimp that thrive in its waters, and provides critical nesting habitat for two million annual migratory birds that feed on the shrimp.

The human history of Mono Lake is associated with its productive ecosystem. The native Kutzadika'a people derived nutrition from the larvae of the alkali flies that live in the lake. When the city of Los Angeles diverted water from flowing into the lake, it lowered the lake level, which imperiled the migratory birds. The Mono Lake Committee formed in response, winning a legal battle that forced Los Angeles to partially restore the lake level.

Eye of Africa, Mauritania

The Eye of Africa — whose official name, the Richat Structure, seems so mundane in comparison — was spotted in central Mauritania by astronauts on early space missions. In the expanse of the Western Sahara Desert, the formation has a diameter of about 48 kilometres. At first, scientists thought a meteorite had hit the Earth, causing this impression. But now it is believed to be a symmetrical uplift that erosion has revealed. No one has explained yet why it is circular.
