10 Amazing Natural Places in the World

1. Zhangye - China

Danaxia landforms are colourful rock formations at the Zhangye Danxia Landform Geological Park in Gansu Province, China. The landform is a unique type of petrographic geomorphology which is found only in China which consists of red-colored sandstones and conglomerates of largely Cretaceous age.
Research shows that about 100 million years ago, there used to be a huge inland basin here. Water carried silt from the surrounding mountains to the basin. As the result of global high temperatures the basin dried up and in these arid conditions the sediment oxidized and turned rust color. Then some 70 million years ago a 3,700-meter-thick red-colored layer formed on the basin, known as the chalk bed. On the top, there was a 1,300-meter-thick solid layer, i.e., layer of Cretaceous system, from which the peaks of Danxia Mountain gradually took shape.

2. Grand Prismatic Spring - USA

The Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world, after Frying Pan Lake in New Zealand and Boiling Lake in Dominica. It is located in the Midway Geyser Basin.
Grand Prismatic Spring was noted by geologists working in the Hayden Geological Survey of 1871, and named by them for its striking coloration. Its colors include blue, green, yellow, orange, gold, red and brown, and recall the rainbow dispersion of white light by an optical prism.

3. Salar de Uyuni - Bolivia

Salar de Uyuni (or Salar de Tunupa) is the world's largest salt flat at 10,582 square kilometers (4,086 sq mi). It is located in the Potosí and Oruro departments in southwest Bolivia, near the crest of the Andes and is at an elevation of 3,656 meters (11,995 ft) above mean sea level. The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar. The crust serves as a source of salt and covers a pool of brine, which is exceptionally rich in lithium. It contains 50 to 70% of the world's lithium reserves, which is in the process of being extracted. The large area, clear skies, and the exceptional flatness of the surface make the Salar an ideal object for calibrating the altimeters of Earth observation satellites. The Salar serves as the major transport route across the Bolivian Altiplano and is a major breeding ground for several species of pink flamingos. Salar de Uyuni is also a climatological transitional zone since the towering tropical cumulus congestus and cumulus incus clouds that form in the eastern part of the salt flat during the summer cannot permeate beyond its drier western edges, near the Chilean border and the Atacama Desert.

5. The Pink Lake - Senegal


Lake Retba or Lac Rose lies north of the Cap Vert peninsula of Senegal, north east of Dakar.
It is so named for its pink waters, caused by Dunaliella salina algae in the water that produce a red pigment that uses sunlight to create more energy, turning the waters pink. The color is particularly visible during the dry season. The lake is also known for its high salt content, which, like that of the Dead Sea, allows people to float easily. The lake also has a small salt collecting industry and was often the finishing point of the Dakar Rally, before it moved to South America in 2009.
Many salt collectors work 6–7 hours a day in the lake, which has a salt content of up to 40% in some areas. In order to protect their skin, they rub their skin with "Beurre de Karité" (shea butter, produced from shea nuts obtained from the Shea nut tree), which is an emollient used to avoid tissue damage.
Lake Retba is under consideration by the World Heritage Committee for inclusion as a World Heritage Site.

6. The Stone Forest - Madagascar

Tsingy de Bemaraha Strict Nature Reserve is a nature reserve located near the western coast of Madagascar in Melaky Region. The area was listed as a UNESCO World Heritage Site in 1990 due to the unique geography, preserved mangrove forests, and wild bird and lemur populations. The southern end of the protected area has subsequently been changed into the Tsingy de Bemaraha National Park, covering 666 square kilometres (257 sq mi). The northern end of the protected area remains as a strict nature reserve (Réserve Naturelle Intégrale) covering 853 square kilometres (329 sq mi).

7. Mt. Roraima - Venezuela

Mount Roraima, also known as Tepuy Roraima and Cerro Roraima is the highest of the Pakaraima chain of tepui plateau in South America. First described by the English explorer Sir Walter Raleigh in 1596, its 31 km2 summit area is defended on all sides by tall cliffs rising 400 metres (1,300 ft). The mountain includes the triple border point of Venezuela, Brazil and Guyana.
Mount Roraima lies on the Guiana Shield in the southeastern corner of Venezuela's 30,000 square kilometres (12,000 sq mi) Canaima National Park forming the highest peak of Guyana's Highland Range. The tabletop mountains of the park are considered some of the oldest geological formations on Earth, dating back to some two billion years ago in the Precambrian.
The highest point in Guyana and the highest point of the Brazilian state of Roraima lie on the plateau, but Venezuela and Brazil have higher mountains elsewhere. The triple border point is at 5°12′08″N 60°44′07″W, but the mountain's highest point is Maverick Rock, 2,810 metres (9,219 ft), at the south end of the plateau and wholly within Venezuela.

8. Hang Son Doong Cave - Vietnam

Sơn Đoòng cave is a cave in Phong Nha-Kẻ Bàng National Park, Bố Trạch district, Quảng Bình Province, Vietnam. Currently the biggest known cave in the world,  the cave is located near the Laos-Vietnam border (17°27'25.88"N 106°17'15.36"E). It has a large fast-flowing underground river inside.
Sơn Đoòng Cave was found by a local man named Hồ-Khanh in 1991. The local jungle men were afraid of the cave for the whistling sound it makes from the underground river. It was not until 2009 that it became public after a group of British scientists from the British Cave Research Association, led by Howard and Deb Limbert, conducted a survey in Phong Nha-Kẻ Bàng from April 10 through April 14, 2009. Their progress was stopped by a large calcite wall.
According to the Limberts, this cave is five times larger than the Phong Nha cave, previously considered the biggest cave in Vietnam. The biggest chamber of Sơn Đoòng is more than five kilometers long, 200 meters high, and 150 meters wide. With these dimensions, Sơn Đoòng overtakes Deer Cave in Malaysia to take the title of the world's largest cave.

An exit from the cave was found in 2010. The group that scaled the 200 meter high wall found cave pearls the size of baseballs, an abnormally large size.

9. Crystal Cave - Mexico

Cave of the Crystals or Giant Crystal Cave is a cave connected to the Naica Mine 300 metres (980 ft) below the surface in Naica, Chihuahua, Mexico. The main chamber contains giant selenite crystals (gypsum, CaSO4·2 H2O), some of the largest natural crystals ever found. The cave's largest crystal found to date is 12 m (39 ft) in length, 4 m (13 ft) in diameter and 55 tons in weight.
The cave is extremely hot with air temperatures reaching up to 58 °C (136 °F) with 90 to 99 percent humidity. The cave is relatively unexplored due to these factors. Without proper protection people can only endure approximately ten minutes of exposure at a time.

10. Door to Hell - Turkmenistan
Note: No is a totally natural phenomenon, but this so integrated that it seems to be natural.

The Door to Hell is a natural gas field in Derweze (also spelled Darvaza, meaning "gate"), Ahal Province, Turkmenistan. The Door to Hell is noted for its natural gas fire which has been burning continuously since it was lit by Soviet petrochemical scientists in 1971, fed by the rich natural gas deposits in the area. The pungent smell of burning sulfur pervades the area for some distance.
The field is situated near the Derweze village. It is in the middle of the Karakum Desert, about 260 kilometres (160 mi) north from Ashgabat. The gas reserve found here is one of the largest in the world. The name, "Door to Hell", was given to the field by the locals, referring to the fire, boiling mud and orange flames in Derweze's large crater with a diameter of 70 metres (230 ft). The hot spots range over an area with a width of 60 metres (200 ft) and to a depth of about 20 metres (66 ft).
The site was identified by Soviet scientists in 1971. It was thought to be a substantial oil field site. The scientists set up a drilling rig and camp near by, and started drilling operations to assess the quantity of gas reserve available at the site. As the Soviets were pleased with the success of finding the gas resources, they started storing the gas. The ground beneath the drilling rig and camp collapsed into a wide crater and disappeared. No lives were lost in the incident. However, large quantities of methane gas were released, creating an environmental problem and posing a potential danger to the people of the nearby villages.
Fearing the release of further poisonous gases from the cavern, the scientists decided to burn it off. They thought that it would be safer to burn it than to extract it from underground through expensive methods. Environmentally, gas firing is the next best solution when the circumstances are such that it cannot be extracted for use. Methane gas released into the atmosphere is also a dangerous greenhouse gas whose potential for global warming is much higher than that of the carbon dioxide created when it burns. At that time, expectations were that the gas would burn within days, but it is still burning, four decades after it was set on fire.
