Il existe tellement de mystères époustouflants dans le monde naturel dans lesquels vous voudrez plonger. Par exemple, le bourdonnement étrange que les gens entendent partout dans le monde sans source ni explication claire. Ensuite, il y a le phénomène fou de la foudre en boule, où des orbes lumineuses apparaissent pendant les orages. Et n'oubliez pas les mystérieuses pierres mouvantes de la Vallée de la Mort – elles laissent des traces derrière elles, mais personne ne sait comment elles se déplacent ! Animation créée par Sympa.

00:00In the Baltic Sea, there is an enigmatic national park.
00:03The Enchanted Forest is a place that no scientist has managed to explain so far.
00:08The pine trees are all bent and twisted in a loop and in a spiral.
00:12This forest has only existed since the early 1960s,
00:15the time when the trees were planted to make the sand of the dunes of this area more stable.
00:20According to a theory, it is the lack of stability of the soils that would have caused the deformation of the pine trees.
00:26Other theories put these twisted trees on the account of the power of the winds or of supernatural forces.
00:32According to some, positive and negative energies would converge in the forest, causing these strange forms.
00:38A local legend says that by passing through the circle of a tree,
00:41you add a year to your life or that you can make a wish.
00:44I like this legend.
00:46And since we are talking about weird trees, there is one that grows in the Piedmont region in Italy.
00:51If you travel, you will see a cherry tree that grew at the top of a wall.
00:55And the strangest thing is that both trees are in perfect health.
00:59A permanent storm rages in the north pole of Saturn and its shape is very strange.
01:04It is hexagonal.
01:05This is probably due to the gradient of the winds.
01:07The total length of this cloud configuration is 14,500 km,
01:12which represents about 1,900 km more than the diameter of the Earth.
01:17We have been observing this hexagon for years, but the most mysterious thing is that it changes color.
01:22It used to be turquoise and has recently turned golden.
01:26The reason for this change in color is that the pole is progressively exposed to sunlight as the seasons change.
01:33Rain is not uncommon in Oakville, in the state of Washington.
01:37But the one that fell one day in the form of frost clouds is still to this day without a precise explanation.
01:43We witnessed this strange rain on an area of ​​about 58 km².
01:48Those who approached it later felt symptoms similar to those of the flu.
01:52So what were these clouds?
01:54Scientists claimed that they contained human white blood cells.
01:57Subsequent tests, however, denied the presence of cores characteristic of lococytes.
02:02Some then said that they could be evaporated jellyfish,
02:06or even waste from a airliner.
02:09Slippery stones, also called moving stones,
02:12move alone in the National Park of the Valley of Death in California,
02:16leaving long traces in the earth and sand on their way.
02:20Several accelerated sequences have been carried out to testify to the strange phenomenon.
02:25Scientists have even installed GPS navigators on some stones,
02:29to demonstrate their considerable speed.
02:31According to several researchers, these movements are due to thin layers of ice
02:35that form during the night in the valley and slide the stones before melting during the day.
02:41But maybe someone is just listening to the Rolling Stones in the corner.
02:45No, probably not.
02:47The crater of Batagaika, in Siberia, looks like the entrance of hell.
02:52It is about 1 km long and more than 86 m deep.
02:56But it keeps growing.
02:58The deeper it gets, the more it exposes its underground layers.
03:01These strata reveal to us what our planet looked like thousands of years ago.
03:06And the depressions tell us about the climates of the past.
03:09The crater appeared in the 1960s on the occasion of a rapid deforestation.
03:13Trees no longer cast shadows on the ground and the heat increased.
03:17The melting of the permafrost then led to the formation of the crater.
03:21The Taos flood in New Mexico has been driving the inhabitants of this city crazy since the 1990s.
03:31This low-frequency noise deprives people of sleep and exhausts them.
03:35Scientists have tried to find the source of this flood in wine so far.
03:40Various floods have also been heard in the United Kingdom, Australia, Canada and other regions of the United States.
03:47Fortunately, only 2% of the world's population is able to hear them.
03:51Their cause is attributed to mechanical devices, to various disturbances in the auditory system and even to certain animals.
03:58The West Seattle flood, for example, was attributed to toadfish.
04:03The circle of fairies, also called ring of witches or annular mycelium,
04:08is a mysterious circular formation of mushrooms that appears in meadows and forest areas.
04:13The reasons why these mushrooms align in this way are the subject of many debates.
04:18According to some superstitions, the fairies, by dancing, would burn the soil,
04:22which would cause a rapid growth of the mushrooms.
04:25In Costa Rica, a set of about 300 megalithic spheres was discovered.
04:30The inhabitants call them Las Bolas, which simply means balls in French.
04:35These stones are almost perfectly round.
04:37Some of them are huge, weighing up to 16 tons.
04:41In addition, they are made of different materials, gabbro, limestone and grey.
04:46They were once placed right in front of the chiefs' residence, but their origin is still unknown to us.
04:51Some claim that these stones are native to the Atlantic.
04:56If you go to see the Mekong at the end of October,
04:58you will have the chance to see luminous balls emerge from the water and rise in the air.
05:03The inhabitants of the region call these luminous balls fireballs of the Nagas.
05:07The size of the fires varies.
05:09These reddish balls can be as small as a spark and as large as a basketball.
05:14There can be dozens or even thousands of balls every night.
05:18Scientists have no precise explanation for this phenomenon,
05:22but it could be due to the flammable gases released by the swamps.
05:26Some superstitious inhabitants believe that they are due to a giant snake that lives in the river.
05:31In Minnesota, on the northern bank of Lake Superior,
05:34there is a park, especially known for sheltering the Devil's Kettle.
05:39It is a waterfall that separates in two.
05:42One part of the river continues, while the other part disappears into a hole in the ground.
05:46If you throw an object into the Devil's Kettle, it will not reappear.
05:50Scientists still do not know where the water that falls into the hole goes.
05:54The Devil's Kettle is considered dangerous because it is almost impossible to trace the course.
05:59And yes, not the best place to do tubbing.
06:02The grunions are fish known for their strange mating rituals.
06:06Females come out of the water and climb on the shore.
06:09They sink their tails into the sand to lay eggs there.
06:12After fertilization by the males, the eggs remain hidden in the sand.
06:16The high tide arrives and carries the hatchlings to the sea.
06:20Scientists still can not explain this reproduction mode.
06:24The inhabitants of the countryside in the center of Norway, above the valley of Esdalen,
06:29can often see white, yellow and red floating lights crossing the sky.
06:34These lights appear day and night, and in the 1980s,
06:37they were even seen between 15 and 20 times in a single week.
06:42The lights of Esdalen can last a few seconds and sometimes more than an hour.
06:47The lights move, seem to float or even swing.
06:50Some scientists believe that it is ionized iron dust that is at the origin of these lights.
06:55Others say that the phenomenon is due to a combustion of sodium, oxygen and hydrogen.
07:00You arrive under the California sun and you go for a hike in the mountains of Santa Lucia.
07:06There, you have a strange and unpleasant feeling, as if someone was watching you.
07:12You look around you, but you see no one.
07:15It is then that you look at the top of the mountains in front of you, and your heart pounds.
07:20On the peaks, you can see the silhouette of a gigantic humanoid.
07:24His arms are tense and a magnificent rainbow surrounds him.
07:28This mysterious silhouette is entirely dressed in black.
07:31You cannot distinguish facial expressions or details, but you can see him move.
07:36Then, he disappears before your eyes.
07:38Congratulations, you have just witnessed the Dark Watchers,
07:42a phenomenon that terrifies hikers in the California mountains for more than 300 years.
07:47Even today, scientists cannot give a precise explanation for these mysterious apparitions.
07:53What we know is that it is completely natural.
07:57Well, probably.
07:59A theory claims that there is no silhouette at all.
08:02The human brain simply imagines images created by the shadows that the clouds project on the mountains.
08:08Over the centuries, people have shared stories about this legend,
08:12and their minds begin to shape them by building recognizable images.
08:16The same thing can happen, for example, when you see the outlines of a human face on a piece of grilled bread,
08:22or the shape of a dog in a passing cloud.
08:25The most accepted scientific explanation is what is called a Brocken Spectrum.
08:30It is when the sunlight is distorted by clouds or mist droplets.
08:35This explains the rainbow surrounding these figures.
08:38As for the shadow, it is only yours that is stretched and projected on the mountains in front of you.
08:44After all, these figures usually appear when the sun is behind the witness.
08:49Natural or not, the mysterious characters that disappear scare you to death.
08:54So you head east, and you find yourself in the desert.
08:57The scorching sun falls on your back.
09:00There is nothing for hundreds of kilometers in a row.
09:03It is hard to believe that this dry plain and lifeless was once the bottom of a lake.
09:08You see a long track in the sand, as if someone was pushing or pulling something very heavy on the ground.
09:14You follow the strange track, and in the end you find a huge stone.
09:20Why would someone drag such a heavy rock in the middle of the desert?
09:24But nothing or no one touched this stone. It moved on its own.
09:28It is a phenomenon called moving stone.
09:31Every winter, the ice covers the ground here.
09:34When a strong wind blows, the stones begin to move on this slippery surface.
09:39Once the ice has melted, there is only a winding path behind a single stone.
09:45Well, to relieve us of the scorching sun of California, let's go to Antarctica.
09:50Snow, ice, and ... another bright sun.
09:54Well, it's a desert too.
09:56The light is almost blinding.
09:58You look up, and in the distance you see something red that separates from all this infinite white.
10:04As you approach, you realize that it is a waterfall.
10:07A sinister red waterfall that flows from the glacier.
10:11Splashes fly in all directions and stain the white snow.
10:15Don't worry, these so-called Blood Falls are nothing like that.
10:21Millions of years ago, I was not there,
10:24a glacier formed above an extension of water and blocked its access to sunlight, heat and oxygen.
10:31Then the lake managed to pierce the glacier with a small stream of water.
10:35When this salty water meets oxygen, it creates this rusty and scarlet color.
10:41It is the only waterfall of this type in the world.
10:44Now, in the city of Taos, in New Mexico,
10:47the inhabitants hear a strange rumbling every day.
10:51But not all.
10:53For some reason, only 2% of the residents can hear this sound.
10:57Some theories advance that it is due to the unusual acoustics of this place.
11:01Others see a strange auditory hallucination, or even something more sinister.
11:08Inexplicable sounds also occur in other worlds.
11:12In 2020, the Martian rover recorded a strange rumbling from the Red Planet.
11:19In the high altitudes of northern China, there is a mountain that remains frozen all year.
11:24It is a natural place of cold land.
11:27A thick layer of pergélisol is under the upper layer of the mountain soil, freezing everything above it.
11:33This frozen land pocket, which defies the climate, covers more than 7.9 meters of the slope of a mountain in the Ping-Kwan county.
11:40A famous place for its torrid summers, which reach 32.2 ° C.
11:45This frozen land area manages to survive the torrid temperatures thanks to the dense layer of soil that covers the permafrost.
11:52This soil prevents the hot weather from reaching and melting the pergélisol, which allows the soil to remain frozen all year.
11:59Argentina may be famous for its beautiful beaches and its scorching sun, but it is in the south of the country that the Perreto Moreno glacier is located.
12:06This amazing blue glacier covers more than 259 square kilometers and never ceases to grow.
12:11By visiting this natural wonder, you may see an ice arch forming on the side of the glacier and going to the neighboring land.
12:18Suddenly, it breaks and the ice melts in the water below.
12:21It is quite natural. The glacier follows a formation process of these arches until they melt.
12:27It will form another one in no time.
12:30On the beach of Glass Beach, in California, there is no sand, but only colorful pebbles that look like precious stones, called sea glass.
12:38Curiously, these magnificent pebbles come from waste.
12:41For decades, the beach has served as a gigantic landfill for the inhabitants who abandoned their glasses, their household appliances and even their cars on the seashore.
12:50The state ended up prohibiting anyone from getting rid of their waste on the beach.
12:54Over the years, the waves have decomposed all the remaining waste and transformed it into colorful pebbles that attract tourists from all over the world.
13:02The highest waterfall in the world, Salto Angel, is located in southern Venezuela.
13:07The water flows along one of the largest mountains in the shape of a Venezuelan plateau and plunges 762 meters downstream, into the jungle.
13:14It is three times higher than the Eiffel Tower.
13:17The water falls so high that most of it evaporates in fog before even reaching the ground.
13:22Visitors can feel the mist set on their skin more than a kilometer away.
13:27In Scotland, Fidich Glen is hidden far from the main roads and nestled in the heart of the forests.
13:34This region looks like an old fairy tale with its rocky formations covered in moss and its red and scarlet waters.
13:40The red color of the water is due to the sand at the bottom of the river, which is shallow.
13:45To access this amazing natural beauty, you have to embark on a dangerous hike along muddy and steep hills, climbing on trees to avoid falling.
13:54But when you finally get to the bottom, it's worth looking at the sun's light shining on the ruby waters and seeing the imposing rocks of this extraordinary world.
14:02With its pink water and the emerald green forests around it, it is hard to believe that Lake Hillier is a real place.
14:09No one can really explain why the lake, located in Western Australia, has this pink color.
14:15However, scientists have hypothesized that the large amounts of salt present in the lake have attracted a pink bacterium that loves salt, called Allobacterium,
14:23which is responsible for this characteristic color of the lake.
14:27In a small peninsula in South America, there is one of the most beautiful natural wonders in the world, the marble caves.
14:34From the outside, these caves look like any other.
14:37Inside these caves, the walls are made up of blue, wavy and smooth marble formations.
14:43For thousands of years, the water has eroded the marble deposits inside these caves, thus forming this unique system of caves.
14:51While the deep blue color seems to be part of the marble, it is actually the reflection of the water that causes these shades of blue along the walls of the cave.
14:59The volcanoes of Azerbaijan are exactly what we think they are.
15:02More than 300 of these natural phenomena are located in Azerbaijan, that is, more than anywhere else in the world.
15:08There have been more than 200 eruptions since they began to be documented.
15:12The mud volcanoes are forms of relief caused by the eruption of mud, water and gas.
15:18Gas pockets form underground and rise to the surface, to finally erupt and project mud everywhere.
15:25These volcanoes can be quite dangerous.
15:27In 2006, a mud volcano erupted in Indonesia and covered a thick mud all over a neighboring village.
15:34Pamukkale is a wonderful hill made up of thermal swimming pools.
15:38The name of the Turkish city translates to Cotton Castle.
15:41The pools are made of travertine, a type of limestone that gives the hill its amazing white color.
15:47In addition, this stone has geothermal properties that make the pools hot springs.
15:52There are 17 pools in total and all are open to the public 7 days a week.
15:57Temperatures range from 35 ° C to 100 ° C.
16:00They are ultimately natural versions of a jacuzzi.
