With progressive science, many secrets of the Earth have already been discovered. We have already reached the surface of the Moon and explored other planets. But there are still some of the most mysterious places on Earth that have yet to be explored. Here is a list of the best undiscovered places on Earth.
Unfavorable conditions and destructive natural forces make some places the least explored. On the other hand, it is protection. Because this will help preserve even a few places in their original form.
The most mysterious places on earth
The endless island of Greenland
Greenland is the largest island in the world. This is also the most Nordic country in the world. 80 percent of Greenland is covered in ice. This is the exact reason why Greenland remains the least explored and least populated. By 2016, living on this big island only 56,250 people.
Some of the ice sheets on this island are 3,200 meters thick. There are also glaciers on the island, deep rivers, ice, sun, hot springs and Northern lights. In case of transport, there are no roads or railway networks in Greenland, and to get through you can choose a snowmobile, boat, plane or helicopter.
Mariana Trench in the Western Pacific Ocean
Mariana Trench is the deepest part on Earth, located in the western part Pacific Ocean. This deep, crescent-shaped trench was formed in the ocean millions of years ago. Given the depth and high pressure in the Mariana Trench, it is a dangerous place to explore.
So far, there have been only two successful manned descents into the depression. The first descent was made by Swiss oceanographer Jacques Piccard and Lieutenant Don Walsh in 1960. The second mission was carried out by famous Hollywood director James Cameroon in 2012.
The Mariana Trench is home to many rare minerals and ocean creatures. The floor of the Mariana Trench contains fossils.
Unclimbed peak Kankar Punsum in Bhutan
Kankar-Punsum is the most high mountain, not passed in the world. It is located in Bhutan. Even at the most high peak, Mount Everest has already been successfully climbed by many people. But no one has ever managed to reach the top of Kankar Punsum.
In total, four expeditions took place there. In 1983, 1985, 1986 and 1994 respectively. But all these expeditions were unsuccessful due to heavy snowfall and unstable conditions. in 2004, the Bhutanese government restricted mountaineering in Kankar Poonsum due to spiritual beliefs. So, the mountain became unclimbed and unknown. 
Lifeless Deserts
This known fact that deserts are the least explored due to poor weather conditions. Sahara is the most big desert in the world. It covers more than 200 million square miles. The Sahara is located in Africa and is the largest and hottest desert in the world.
Deserts receive very little rainfall per year. Dramatic temperature fluctuations are also very common in deserts. The days can be quite hot. But the nights are very cold. This makes for very harsh conditions for animals, plants and humans. Although, some animals and plants can be found in deserts. Such animals are highly technologically advanced to live in harsh conditions. 
Unknown Deep Caves
There are a large number of unexplored caves located throughout the world. Too difficult to explore many caves due to unbearable weather conditions and sharp rocks
Also some underwater caves in the world are unexplored, even there is no marine life due to the deadly conditions. Flooded, Yucatan Cenotes, cave networks in Mexico are the best example for this. The Crystal Caves and Snow Caves have become too dangerous for expeditions due to unprecedented changes. 
Boundless Amazon, South America
With a total area of 2.5 million square kilometers, the Amazon contains half tropical forests on the ground. Rich biological diversity and abundance of rare species make the Amazon popular for scientific expeditions. But the mysterious Amazon is a dangerous habitat.
There is no dry season in the Amazon rainforest; it rains throughout the year. Heavy rain in the Amazon rainforest begins in February. This leads to a sharp rise in the water level in the river and severe flooding. In such conditions, transport across rivers also became too dangerous due to extreme river currents.
The Amazon is also dangerous because of deadly animals such as jaguars, rattlesnakes, Brazilian wandering spiders, mosquitoes, poisonous frogs, piranhas, black caimans and anacondas, which can even harm humans. Additionally, lack of access to healthy food and clean water makes an expedition into the Amazon rainforest too dangerous. 
Icy Antarctica
Antarctica is the coldest place on the surface of the Earth. It is a dry, cold, windy continent. The climate in Antarctica varies dramatically from -10 degrees Celsius to -30 degrees Celsius under normal conditions. The lowest recorded temperature in Antarctica is -89 degrees. This harsh climate of Antarctica itself makes for dangerous research conditions.
The maximum wind speed recorded in Antarctica was 200 mph in 1972. The ice in Antarctica is 2 miles thick. It reflects the unbearable climate conditions on the continent. Heavy snow, glaciers, crevasses and other potential hazards in Antarctica. Therefore, this place is very difficult to explore. 
Let's look at the most unusual corners of our planet. We will talk about unusual landscapes that evoke admiration just by their appearance - these are real wonders of nature.
Let's start with the most unearthly part of our planet - the Dry Valleys in Antarctica. This desert is unique in that it is dry place on the ground. There has been no precipitation here for several million years. This place is closest in climate to Mars, and therefore is of particular interest to NASA. Mars rovers are tested here and large-scale research is conducted in all directions. This is the only part of Antarctica that is not covered with ice. In the valleys there is a frozen lake with extremely salty water, mysterious bacteria and organisms were discovered under the ice - this discovery served as confirmation of the theory that life exists on Mars
In second place is the island of Socotra - the landscapes of this island are unique and look more like alien ones. The island has been geographically isolated from Africa for 6 million years and is home to many extremely rare species of flora and fauna - a third of which are endemic and can only be found here. Despite the hot and dry climate, many amazing and beautiful plants grow here, many of which are about 20 million years old.
Next on the list of “The most unusual places on Earth” is the Rio Tinto quarry in Andalusia, Spain. The huge quarries of Rio Tinto create a surreal, lunar-like landscape. The quarries are named after the river of the same name, which flows here and washes minerals out of huge craters. Mining has been carried out here for many centuries, so the river is painted a bright red-orange color, its acidity and saturation with metals is simply off scale. Currently, mining in this region has ceased, and Rio Tinto attracts crowds of tourists and photographers to Andalusia.
Let's move on, I still have something to surprise you with :) I bet that you have never heard of Spotted Lake, much less seen such stunning landscapes. The lake is located in British Columbia, Canada. Depending on weather conditions and the time of year, the lake crystallizes and turns a certain color. Many “spots” – circles of minerals – form on the lake. This is the world's largest concentration of magnesium sulfate (Epsom salt), calcium and sodium, as well as silver and titanium. This place is sacred to the indigenous Indians of Canada, and is famous for its medicinal properties- for this he was given the name Kliluk.
Another unusual landscape - the largest in the world salt Lake, Salar de Uyuni. This is a beautiful area with a huge salt desert, active volcanoes, large islands cacti and geysers. You can ride on the surface of the lake in a jeep and admire the unusual, sometimes unearthly beauty of this place. The Uyuni salt marsh is clearly visible from space and is one of the points for satellite calibration.
There is another unusual place in Brazil - Vale da Lua, which means Valley of the Moon. It is a water-washed rock formation with natural swimming pools. Vale da Lua is located in the Brazilian Chapada forest and is one of the oldest rock formations on the planet consisting of quartz and crystals.
There are also unusual places in Japan. This is the Bloody Pond, one of Beppu's famous springs. There are nine unusual geyser springs in this city, but the most famous among them is the Bloody Pond with hot water bright red color. This color is due to the high iron content in the water. This pond is also the most photogenic among all the sources.
Coming eighth on our list is the Shilin Stone Forest in China, a stunning example of karst topography. The rocks are made of limestone and were formed by water, which destroyed everything except these tree-like pillars. Since the Ming Dynasty, Shilin Stone Forest has been known as the “First Wonder of the World.”
Another miracle of nature is the Richat Structure in Mauritania. It is also called the Eye of the Sahara. Richat is about 30 miles in diameter and is visible from space. The formation was originally thought to be the result of a meteorite impact, but modern geologists believe that the Richat structure is the result of erosion. The reason for its round shape is still a mystery that scientists around the world are struggling with.
The famous gate to Hell - Darvaz in Turkmenistan, was also included in the list. This place frightens with its power, thousands of tons of lava and heat emanating from the bowels of the Earth. There is a burning crater in the middle of the Karakum desert, its diameter is 60 meters and its depth is 20 meters. At its core, Darvaz is a gas well, and the history of its discovery is quite interesting. Researchers drilled a well here to extract gas, but as a result this huge abyss opened, the gas had to be set on fire so that no one would be poisoned.
Closing the list of the most unusual places on the ground are the ice caves of Eisreisenwelt. These caves are different from any other caves because of their icy strangeness. Once you get here you feel like you're somewhere else. fairy tale world. There are many in the world ice caves, but the Eisreisenwelt caves are the largest among them. Their total length is 40 kilometers, and only a small part is open to the public. But even this is enough for thousands of tourists every day to admire the grandeur and unusualness of this place.
Many people think that since modern technologies have allowed us to begin exploring the Moon and Mars, launching spacecraft to Jupiter, Saturn and other planets, then there are no longer any secret and unexplored corners on Earth. In fact, this is completely true.
But today there are quite a lot of areas on the globe that remain, for one reason or another, little studied, where a person’s foot has stepped at most a couple of times. We have collected 10 of the most unexplored corners and places of our planet.
1. Northern Columbia Mountains
Multi-tiered mountain ranges with a system of caves, picturesque areas and dense vegetation are unlikely to be suitable for your solitude, since they serve for the solitude of other people - namely Colombian drug dealers. Having captured this completely unexplored territory, they keep it in complete submission, thanks to the fact that the mountains are very difficult to storm, and the lush year-round green vegetation provides excellent cover.
However, dedicated scientists, who conduct scientific expeditions there at their own risk, talk about new unique discoveries in animals and flora, especially in intermountain isolated valleys.
2. Angel Falls
Also known as Kerepakupai vena, meaning "Waterfall" deepest place" This is the tallest continuous waterfall in the world. It is located in the tropical forests of Venezuela, in the territory National Park Canaima. Water cascades from the top of Auyantepui, the largest of the Venezuelan tepuis - its name means “mountain of the devil” in Russian.
The water falls from a staggering height of 979 m. The waterfall was named after Jimmy Angel, the US pilot who was the first to fly over this waterfall. This place remains one of the most inaccessible on Earth due to dense jungle and lack of means of transportation.
3. Papua New Guinea
An open but unexplored land, which amazes with its landscapes, diversity of fauna and other natural beauties, also delights researchers with discoveries in the human world. The whole point is that more and more new tribes and cultures are found there, most often cannibalistic, which, by the way, interfere with the exploration of this territory.
If you still decide to admire the pristine beauty of nature without smoking chimneys, admire the rivers without waste flowing into it, and still go to Papua New Guinea, then remember that you will have to be extremely careful in this little-explored area - the population is unfriendly, and If help comes, it will be extremely untimely.
4. Greenland Ice Sheet
Greenland has the second largest ice sheet in the world (after Antarctica), and the island is used as a testing ground for fundamental research on glaciers: glaciologists here study glacier dynamics, microbiologists study ancient life trapped in ice. However, the most significant aspect remains the study of the paleoclimatic aspects of the research, since the ice has air inclusions that can provide information about the atmosphere of the past. A total of six deep wells have been drilled in Greenland, and the least explored place is the Northern edge of Greenland, the Lincoln Sea and other surrounding ice-covered waters. Throughout their history, only a few ships have visited here, among them were ours nuclear icebreakers. But all this icy desert is gradually melting, and at current rates the shield will disappear within 2,000 years.
5. Tristan da Cunha
Temperate warm climate, rich fauna and flora, south Atlantic Ocean– what could be better than solitude and quiet old age? In addition, it is extremely difficult to get here, there is no way by air - only by sea, and only on certain days when the sea is calm and there is no danger of running into a rocky ridge.
However, there is Internet on the island, there is radio communication, so everything a modern person needs to be happy can be found there. Disadvantages - about 300 more people have chosen such a heavenly place; you will have to put up with this company, as well as the fact that you will have to produce food yourself - catch fish with homemade nets or plow on plantations like those same 300 people.
6. Rain forests Amazonia
7. Tibetan plateau
To travel 20 days on foot, travel 81 days and not see a single person, do you think this is only possible on the surface of the Moon? No, this Tibetan plateau is one of the most mysterious places on Earth. With the exception of a handful of monks in certain areas, you risk running into no one here at all, even if you move permanently to a small village.
Cartographers still do not have a general map of the area, and if we talk about blank spots anywhere, then only about Tibet. The championship is held by the border mountains of Gankar Punsum; having chosen these heights, you will have to get to the nearest settlement about a month and a half without the possibility of using any transport.
8. Mariana Trench
Almost the entire bottom of the World Ocean can be called the least explored space on our planet. However, the most mysterious known point is the oceanic deep-sea trench in the western Pacific Ocean. The depression was named after its nearby Mariana Islands, and her most deep point The Challenger Deep is located in the southwestern part. According to measurements in 2011, its depth is 10,994 ± 40 m below sea level. Only 3 people have visited this place: Jacques Picard and Donald Walsh on the bathyscaphe Trieste in 1960, and James Cameron on the bathyscaphe Deepsea Challenger in 2012. The pressure at this depth is 1,106 times the pressure at sea level, but 20 thousand microorganisms were discovered at the bottom of the Challenger Deep. Fauna collected included isopods and six species of shrimp-like amphipods. Further study of the depression, according to scientists, can tell us more about the adaptation of organisms to high pressure and, perhaps, even reveal the secret of the origin of life.
9. Cape York Peninsula
The natural reserve on the northern peninsula of Australia is also famous for the fact that it is extremely difficult to reach, only by air. Large flat areas, where absolutely no one lives, are interspersed with small settlements of aborigines, who are extremely unfriendly to tourists trying to penetrate their protected area.
It is not called a reserve for nothing - only there you can find up to 150 different species of animals and plants, which on Earth are found only in Cape York and nowhere else. Beautiful hilly landscapes and ocean bays still attract extreme tourists, who say that traveling to Cape York is very expensive due to the absolutely undeveloped infrastructure of this part of the mainland.
10. Naica Crystal Cave
This giant cave natural crystals, including the largest ever found. It is located adjacent to the city of Naica, Chihuahua, Mexico. The cave was discovered by miners during excavations of a new tunnel in 2000. It has the shape of a horseshoe. Temperatures reach up to 58 °C (136 °F) and humidity ranges from 90 to 99 percent. Without proper protective equipment, people can only stay inside for about ten minutes due to high temperature. It is noteworthy that access to the cave is provided thanks to pumping activity mining company. If it stops, the cave will again plunge under water.
Unexplored Russia with a territory of more than 17 million square meters. km. - Indeed, it will take several lifetimes to see all its beauties with your own eyes. Or at least understand the scale sung by poets and writers: “My native country is wide, / There are many forests, fields and rivers in it.” “How wide and how much…” we know from school, but is this “dry knowledge” enough?
Russia is a great country, and today there are no people in the world who are indifferent to it. She is either idolized or hated.
Often we want to believe that we know everything about our homeland. But this is far from true. This is especially true for attractions about which we know little. Surprisingly, as mysterious as Russia is for foreigners, it is so unknown to its native inhabitants. And there are a lot of such unexplored places in our country.
Let's try together to take a short trip to the little-known places of our homeland. Whether they are interesting is up to you to judge. So 5 little known places Russia, which are definitely worth seeing:
Lake Darashkol
Photo: National Geographic RussiaThe Altai country is generous with miracles and beauty. Here you can see a fairy tale at every step.
There is in this amazing land the most beautiful place, which is impossible not to fall in love with. Lake Darashkol. From Altai “Dyarash Kol” is translated as “ Beautiful lake" As they say, it is what it is. In fact, it’s not enough to say beautiful, it’s bewitching, charming, unearthly.
The lake is located in the upper reaches of the Ioldo-Ayra valley. A cape crashes into the very middle of the lake from the south, reminiscent of Italy in miniature, that very “boot”. There are low-growing and accessible cedars growing around, and there are a lot of lingonberries and blueberries. The constant change of lighting, almost every minute, gives the lake a special magnetism. The color of the lake can change from bright aquamarine to light green, and all this is literally before your eyes. The waters of the lake are so clean and transparent that all the beauty around is reflected in them, as in a mirror.
Weathering pillars
Photo: pictoday.ru This happened a very, very long time ago. In the forests adjacent to Ural mountains, there lived a very brave Mansi tribe. The men from this tribe had the strength of a bear and the speed of a deer. The leader of the tribe was the wise Kuuschai. And the leader had a daughter - the beautiful Aim.
Rumors about her beauty spread over long distances, and the giant Torev (the bear) also learned about this, and he desired Aim. But the girl did not want to connect her life with the giant monster. And then Torev, together with his 6 giant brothers, went to war against Kuushchai. But, as always, good defeated evil, and brother Aim, the brave and strong Pygrychum, repelled the attack. Using a shiny shield, he directed rays at each of the giants, and one by one they turned into stones.
We, modern children of the Earth, no longer believe in fairy tales about giants. But such a place exists. Tourists simply call these stone sculptures “Pupas”. And the energy here is incredible. Everyone who has ever been to these places repeats this. The Mansi still consider this place holy and do not approach it. By the way, to get to Stolby, you need to go through an equally legendary place - the Dyatlov Pass.
Photo: In fact, these former giants arose from ordinary mountains. For many millennia, these mountains were subjected to natural attack in the form of rain, snow, and wind, which led to the destruction of weak rocks and the emergence of bizarre forms of idols. The pillars are truly majestic, reaching a height of 34 meters. Depending on the viewing angle, they can take on the appearance of a person or an animal.
This place is located in the Komi Republic.
In 2008, the Weathering Pillars were ranked among the 7 wonders of Russia.
Lake Elton
Photo: fg-studio.ru Lake Elton is a unique natural site, which is located in Volgograd region. This reservoir is one of the most interesting salt lakes not only in Russia, but throughout Europe, and there are legends about its healing properties and unique origin.
Elton local residents called the pearl of the Volga steppes. Its depth reaches only 15 centimeters, and only in spring, in places where there is a large accumulation of melt water, the depth can increase to 70 centimeters.
Lake Elton attracts with its healing salt waters and mineral mud. People who visited this healing town say that even nature heals and soothes there.
Here, in the middle of the steppe massifs, you can see sand dunes of natural origin and eye-catching salt mountains.
Curonian Spit
Photo: moya-planeta.ru 
Photo: moya-planeta.ru In the Kaliningrad region there is a unique place called the Curonian Spit. This small, narrow piece of land separates the Baltic Sea from the Curonian Lagoon. The length of the spit is about 98 km, but, unfortunately, not all of it belongs to Russia. Part of the spit passes through the territory of Lithuania.
The migratory route of birds passes through the Curonian Spit, which is why there is a terrible hubbub here in spring and autumn. One of the first ornithological stations in the world was built here.
Photo: Nina Karenina About the origin Curonian Spit there is a legend passed down from generation to generation.
A long time ago, when there was no trace of the Curonian Spit, commander Karvait and his beloved wife lived on the seashore in their beautiful castle. They lived in perfect harmony, but they did not have a child for complete happiness.
And then one day, while hunting, Karvait managed to catch a large elk. And he and his wife decided to make a donation to the good fairy Laima so that she would fulfill their cherished dream of a child. Laima took pity on the couple and gave them a beautiful child. They named the child Neringa.
When the girl grew up and was about to get married, a storm suddenly came and lasted for 13 long years. The waves poured blocks of sand onto the shore, and Neringa saved her land by collecting this sand in her hem. She poured it back into the sea, which is why the Curonian Spit appeared.
Volcano Maly Semyachik
Maly Semyachik Volcano, Photo: Surprisingly, but true: there are still places on our planet where no human has ever set foot! They are only photographed from airplanes or from space orbit.
According to scientists, about thirty percent of the Earth's surface remains to be “explored” by expeditions. Is it a lot or a little? I believe that it is a lot, since we are talking about land. The largest unexplored (or poorly explored) areas are in South America. First of all, it is worth immediately identifying the Amazon basin with its virgin forests. There, even now, in our time, there are tribes that have never had any contact with modern civilization. The forests and rivers of the Amazon keep many secrets. In the jungle you can easily end up as lunch for wild predatory animals. In the rivers, crocodiles and anacondas will happily snack on you.
North-Eastern Siberia is recognized as the second most important “white spot” in the world. There are very few roads there at all. Taiga, mountains, and a very harsh climate do not allow for a good exploration of this vast territory. Other places can only be reached by helicopter. Severe cold (on average minus 45 degrees) in winter, dense hordes of mosquitoes, midges, and gadflies in summer... permafrost. To complete the picture, it must also be said that North-Eastern Siberia is the most sparsely populated territory of Eurasia.
Antarctica is considered the third little-studied place on the planet. Although it has been studied by scientists from several countries for decades, about half of the territory is still only approximately indicated on the map. And even then from the air, and not by other (more reliable in terms of accuracy) methods. The most poorly studied territory of Antarctica is its western part.
In fourth place is Greenland. It is 80 percent covered with ice. And this is really a “white spot” on the maps. Global warming has caused the ice of Greenland to retreat and reveal unknown mountains, depressions, and plains. Even new rivers appeared.
However, there are places on Earth that are less famous in terms of their degree of exploration, but more exotic. For example, northern mountains Colombia. Not a single scientific expedition would dare to go to those places. Cause? This part of Colombia is under the complete control of armed militant groups of drug traffickers. Diplomacy is unknown to them.
Another exotic, but also extremely dangerous place on the planet for research is Papua New Guinea. More than half of its territory has never had any scientific expeditions. Cause? In the mountains and forests of this country there are tribes of cannibals. How many there are is unknown. But they are hostile to any contact with them and, at every opportunity, they capture those who dare to pass through their territory. The end of captivity is always the same - a bloody ritual of eating the aliens.
Getting to know Namibia can be no less dangerous. Its rich wild animal world constantly attracts poachers armed with the most modern small arms. More than 2,500 cheetahs live in Namibia - a quarter of all cheetahs on the planet. Although the constitution of this country has a special article on the protection of wild animals, poachers simply meet with machine-gun fire any attempts to detain them or even photograph them. It is clear that in such conditions there can be no talk of any scientific research.
The Tibetan Plateau is also poorly studied. But here the reason is completely different - an almost Martian landscape, complete desolation, absolute impassability. You will be very lucky if your local guide can guide you correctly. Otherwise, the entire expedition will face certain painful death due to hellish conditions. By the way, cartographers still cannot even create a general map of the Tibetan plateau. You can still go along it in any direction and not know what will be ahead. Monotonous mountains and rocks create the feeling of being on an unknown planet.
On Earth there is not only a part of the land unknown to research. Scientists say that the Moon is much better studied than the sea depths of our planet. And as an example - the Mariana deep-sea trench. Only very recently (in 2011) its relief was obtained from a US military vessel using a multibeam echo sounder. What is there, in the depression itself, is unknown. But one of the last descents of the bathysphere almost ended in tragedy. The strongest titanium cable was “cut” by an unknown sea creature at great depths. Only by some miracle did it not break. What kind of monster tried to “gnaw” a metal cable at a depth of many kilometers?
