00:00We live in an era where we can observe almost every corner of the world using satellites.
00:08We have detailed maps, aerial imagery, and technology capable of studying places thousands of kilometers away.
00:16But seeing and identifying a place on a map is vastly different from truly knowing everything that might be hidden
00:23there.
00:25There are forests where scientists continue to discover unknown species, cave systems whose true extent remains unknown.
00:35Vast areas hidden beneath kilometers of ice and mountains whose peaks no human has ever reached to this day.
00:43In this video, we will explore 10 places in the world that, even in the 21st century, we are still
00:50far from fully understanding.
00:52But before we get started, if you are new to our channel, make sure to hit the subscribe button and
00:58turn on the notification bell so you'll always stay updated on our latest videos.
01:05Kamchatka Peninsula, Russia
01:06In the far eastern reaches of Russia, the Kamchatka Peninsula stretches over a thousand kilometers between the Pacific Ocean and
01:14the Sea of Okhotsk.
01:15The peninsula's interior is filled with volcanoes, glaciers, forests, and valleys with very few roads.
01:22Over 300 volcanoes are found here, and nearly 30 of them are active.
01:27Because of this, it's one of the areas in the world with the most intense volcanic activity.
01:32Because the area is so remote and isolated, some parts of it surprisingly took a long time to be recorded
01:38and studied.
01:39In 1941, geologist Tatyana Ustinova and ranger Anisiphor Krupanin were traveling to a remote part of the Kronatsky Reserve using
01:49sleds and skis and on foot when they discovered a river that they hadn't seen on any maps before.
01:55As they rested, a scalding jet of water suddenly erupted from the ground in front of them.
02:02They had discovered the first known geyser in Kamchatka.
02:05A few months later, they discovered an entire valley full of geysers and hot springs that weren't on maps back
02:12then.
02:13Kamchatka has been studied much more extensively today.
02:15But due to its sheer size and rugged terrain, vast areas remain difficult to explore.
02:22Some of its most remote parts still need to be accessed by helicopter.
02:27Karst Landscape of Phong Nha Khe Bang, Vietnam
02:31In the central part of Vietnam, hidden beneath the jungle, lies the Phong Nha Khe Bang mountain range, which holds
02:38one of the largest underground labyrinths in the world.
02:41Over 470 caves have been recorded here, and approximately 254 kilometers of underground passages have been explored.
02:50But with each new expedition, it becomes clear that the map of the area is still far from complete.
02:56The most famous example is the Sun Dung Cave.
03:00A local resident, Ho Kan, first spotted its entrance back in 1990.
03:05He entered the forest seeking shelter, but lost track of the cave's exact location, and it took years before he
03:14found it again.
03:15In 2009, he guided a British exploration team there.
03:21They discovered an enormous cave with an underground river and massive skylights in the ceiling where plants were growing underground.
03:30And to this day, the exploration still continues.
03:35Between March and April, 2026, a British-Vietnamese expedition discovered 26 new caves and mapped over 13 kilometers of additional
03:46underground passages.
03:50Choco Rainforest, Colombia
03:52In Colombia's Choco region, more rain falls each year than in almost any other place on Earth.
03:59In some parts, it averages around 90 millimeters of rain each day.
04:05This constant humidity, combined with its location between two oceans,
04:10is the reason why one of the highest concentrations of biodiversity per hour hectare in the entire world developed here.
04:18It is estimated that a single mature tree in this rainforest can host as many varied species of life as
04:27you would find in an entire region.
04:30Yet despite this, large parts of this territory remain blank on scientific map.
04:36It is not merely because of its remote location, but because the Choco combines an extraordinary biodiversity with almost zero
04:46infrastructure.
04:47Roads do not reach here, formal studies are few and far between, and gold and platinum mining is expanding even
04:55faster than the science trying to document what is here before it is completely lost.
05:01It is estimated that one quarter of the plants, butterflies, and birds here are found nowhere else in the world,
05:08and there are likely entire species that have never even been discovered or described by scientists.
05:16Namib Desert
05:17Namibia
05:18Along the coast of Namibia lies the Namib Desert, a vast expanse of sand dunes, gravel plains, and isolated mountains
05:28that in some parts stretch directly to the Atlantic Ocean.
05:32Within it lies the Namib Sand Sea, a vast area of dunes covering over 30,000 square kilometers.
05:40Where some of the dunes reach nearly 300 meters high, access to its interior remains limited to this day.
05:50According to UNESCO, there is virtually no permanent infrastructure across the vast Namib dunes, and visitors generally focus only on
06:00the dunes.
06:01Covering an area of over lies the Namib Desert, which stretches deep with endless dunes, and in isolated areas.
06:12Satellite imagery is required to study the regions deep within the desert.
06:18Within it, there are still many stories waiting to be discovered.
06:21Archaeologists have already discovered traces of ancient human presence within the sand dunes, possibly dating back to the Middle Pleistocene,
06:28but only a small fraction of these areas has been thoroughly explored.
06:31The vast distances, the shifting sands, and isolated mountains make exploration incredibly challenging due to their sheer scale.
06:46Underwater Caves of Yucatan, Mexico
06:49Beneath its surface lies the largest underwater cave labyrinth map to date.
06:53It has approximately 347 kilometers of flooded tunnels formed by the connection of two cave systems, SAC Actun and Dos
07:00Ojos.
07:01After more than 11 years of searching by...
07:07The same group of divers...
07:13Not inside it is...
07:15The Namib, which still has sand dunes...
07:25It stretches over a total length of more than a thousand kilometers.
07:29It stretches over a total length of more than a thousand kilometers.
07:30Great Maya aquifer project.
07:32Archaeologists recorded incense burners, vessels,
07:36and small chambers containing offerings scattered across various parts of the cave system.
07:45And the evidence shows that inside, you can find the Namib that still has...
07:57Sand dune areas and roots leading to a world beneath the mountain that spans far beyond belief.
08:04And to this day...
08:07They continue to discover ritual.
08:15Clay pots in the corners of caves that...
08:24Inside, you can find the Namib, which suddenly features sand dunes, isolated mountains spanning over just below 30 leagues.
08:33A land area almost the size of Singapore.
08:38It is surrounded by extremely high and nearly vertical cliffs that...
08:45Are nearly impossible to reach on foot from any direction.
08:51For decades, this place went largely unnoticed.
08:55The first attempts to reach its very bottom, located in Namib.
09:09There are sand dunes and deep inside it, various species of plants can be found...
09:17That were previously unknown to science.
09:23Such as insect-eating plants and sand dunes...
09:33With a thickness of over three kilometers, over decades peeling back...
09:42Reveals whatever lies beneath it.
09:51No satellite or explorer could see what lay beneath the thick ice just by looking at it.
09:56In 1966...
10:00That there were even satellites or explorers uncovering what was beneath the thick ice, using only and separate ones over
10:0830.
10:18Inside it, a researcher examined it.
10:21He found branches and leaves.
10:26This is the evidence showing that Namib still has scientists.
10:30And in 2024, one in the sand, separate.
10:38While studying the area beneath the ice sheet, he accidentally discovered something else.
10:43He discovered the tunnels of the same base that was once the hiding place for a secret Cold War plan
10:48to store hundreds of nuclear missiles under the Arctic.
10:51Beneath Greenland, it's not just rock that can be found.
10:54There, too, lies the history of climate spanning millions of years, as well as other isolated discoveries.
11:01Venezuelan Tepuis over...
11:10In the southeastern part of Venezuela, there are over a hundred flat-topped mountains with nearly vertical walls reaching up
11:19to 1,000 meters high.
11:22These are called Tepuis, remnants of an ancient sandstone formation that began forming over 1.8 billion years ago.
11:32Only three of these can be climbed on foot.
11:36The rest remain almost entirely cut off from the world around them.
11:40And what is most astounding is the effect this isolation has had on the plants and animals.
11:46Each Tepu is like an island in the middle of the continent.
11:51Some ecosystems on their summits have survived and flourished for 70 to 90 million years with almost no contact with
11:59the forest below.
12:01And up to one-quarter of the plants found here are unique to that very Tepui.
12:07They cannot even be found on a neighboring Tepui just a few kilometers away.
12:14Tepui inspired the writing of the lost world, Aoyan Tepui.
12:22One of the largest, with an area of about 700 square kilometers,
12:30features yet another extraordinary sight.
12:36From one of its clefts plunges Angel Falls, the world's highest waterfall, straight from the mountain's summit.
12:44Tcingi de Bemaraja, Madagascar.
12:47Around 200 million years ago, layers of calcite gradually deposited at the bottom of a lagoon,
12:53until an extremely thick limestone formation was created.
12:58After millions of years of rainfall, the water carved this rock into an enormous labyrinth of sharp limestone formations.
13:07That is why the very name Tcingi means a place where one cannot walk barefoot in the Malagasy language.
13:15Some of the stone peaks reach over 60 meters high, and between them are canyons,
13:23caves, and forests hidden below, some of which can only be reached using ropes.
13:28According to local legend, the Vazimba, said to be among the first inhabitants of Madagascar,
13:36took shelter here to escape other groups.
13:39They were protected by the rugged terrain, which was nearly impossible for an army to cross.
13:45Even today, it still serves as a natural barrier, but for a different reason.
13:50The park has an exceptionally high proportion of species found nowhere else, reaching 86%,
13:56and it was only open to the public under controlled conditions in 1998.
14:02There are 11 species of lemurs and dozens of bird species that continue to thrive here,
14:07because for millions of years, very few have set foot in this extremely treacherous terrain.
14:16When this part of the Himalayas was first mapped in 1922,
14:20the maps were so inaccurate that the first team attempting to climb Gankar Puensum
14:25couldn't even find the mountain itself, which stands at 7,570 meters high.
14:31To this day, it remains the highest unclimbed mountain in the world,
14:35with no one having successfully reached its summit.
14:37Meanwhile, much higher mountains like Mount Everest have been successfully climbed for over 70 years.
14:45Between 1985 and 1986, it was attempted four times, but all four attempts failed.
14:53In 1994, the Bhutanese government banned climbing any mountain higher than 6,000 meters.
15:02This was done out of respect for local beliefs, which hold that protective spirits reside on the mountain peaks.
15:09But in 1998, a Japanese team found a way to try to gain access.
15:15They asked China for permission to climb the mountain from the Tibetan side.
15:21Bhutan officially protested, so the permit that had been granted was revoked.
15:25Because of this, the team had to call off their expedition, climbing a nearby, lower peak instead.
15:33Since then, no one has attempted to climb it again.
15:36You don't need a dense jungle or a vast ocean for a place to remain a mystery.
15:43Sometimes, it's enough that two countries can't agree on who actually owns a mountain.
15:49Despite satellites, maps, and scientific expeditions, there are still places on Earth that we surprisingly know very little about.
15:59There are places that remain not fully discovered, beneath kilometers upon kilometers of ice, inside almost impenetrable forests, in the
16:08mountains or deep under the sea.
16:09To see, there are still territories that are only now gradually being revealed.
16:14And likely, many more surprising discoveries are waiting to be found.
16:20New passages, unknown species, landscapes buried underground and places we still don't know exist could now change our understanding of
16:30these regions.
