The Lost Forest World of the World’s Largest Cave

The Lost Forest World of the World’s Largest Cave

In this technologically advanced age of Google Earth and ever expanding exploration of our planet, there are fewer and fewer places that remain hidden from the gaze of humankind. We are exploring the forests, mountains, and seas of the world at an ever growing pace, and the ancient places that once lied in pristine remoteness beyond our grasp are being uncovered for all to see. But what of under our feet? What of the lost realms of the deep places of the world? In the case on one massive cave in Vietnam, a lost, prehistoric world sat hidden for millions of years deep under the forest floor until pure happenstance started our first steps into a place that time forgot.
In 1991, a local farmer by the name of Ho Khanh was walking along a stretch of lush forest within the heart of the Phong Nha Ke Bang National Park in Quang Binh province, near the border between Laos and Vietnam. It was an area that he had passed many times before and he was not paying any particular attention to his surroundings when suddenly the jungle floor opened up beneath him and Mr. Khanh only barely managed to hold on as the ground crumbled beneath him. When he was able to get his bearings, he peered into the gaping chasm that had suddenly appeared out of the thick foliage and saw that there was now a steep drop where he had stood that descended down into darkness. By pure chance and blind luck, this man had discovered an entrance that had remained hidden from man for millions of years into what would turn out to be the largest cave in the world, a behemoth five times larger than the largest known cave at the time.
World's largest cave.
World’s largest cave.
For years the entrance remained unexplored. Locals were afraid to go near it, partly because of the dauntingly steep drop, and partly because of the strange roaring sounds that bellowed out from its depths, later found to be caused by a raging river far below. In addition, there was an eerie mist that seeped out of the cave, a phenomenon caused by the cooler air below meeting the hot jungle air above, which gave the area a surreal, unearthly atmosphere. All of these things conspired to deter the superstitious locals from entering, and so the cave mouth remained unexplored and untouched, just as it had been for countless millennia.
It was not until 2009 that members of the British Cave Research Association undertook an expedition to penetrate into the mysterious jungle cavern and explore the darkness below. By that time the man who originally had found it no longer even remembered exactly where it was, so the team had to ascertain its position from what he could recall and from other locals, who still feared it. It was to be the beginning of a breathtaking journey into an ancient, forgotten realm that no human being had ever set foot in.

The expedition, led by Howard and Deb Limbert, began their descent in April of 2009. The first thing that became quickly apparent was the sheer, enormous scale of the place. Using ropes and harnesses, the team rappelled down a 260 foot vertical drop before they finally reached the bottom, where the thick, absolute silence of the place was said to be almost deafening. An investigation of the surroundings showed that the cave was largely formed of limestone, which had been eroded from under the Annamite Mountains of Vietnam between 2 to 5 million years ago. Upon reaching the bottom, the team did not get far before they came up against a 200 foot wall of muddy calcite, which they called “The Great Wall of Vietnam,” that prevented any further progress.
In 2010, the frustrated team was finally able to traverse the enormous wall and continue their journey. What they found within thoroughly amazed all present; an alien world the likes of which none of the experienced cavers had ever seen. The cave, now known as Son Doong Cave, or “the cave of the mountain river” was far larger than anyone had ever imagined. The largest cavern stretched for over 5 km (about 3 miles), was 650 feet wide, and had walls that soared upwards over 200 m (656 feet), high enough to comfortably fit a modern day skyscraper.

Jutting from this immense cavern were stalagmites and stalactites that were up to 80 meters (265 ft) long, some of the largest in the world. Along the Great Wall of Vietnam were scattered abnormally huge “cave pearls” as big as baseballs, which are formed when dripping water forms layers of calcite around grains of sand over hundreds of years. There were also various rimstone pools dotting the cavern and even a lake. Throughout this mystical landscape meandered a river that ran the length of the cavern and disappeared into the unknown darkness of other caves that branched off from the main one. In all, it was found that the main cavern branched out into a network of over 150 individual, interconnected caves.
The biggest surprise to be found here was a massive forest growing undisturbed deep in the heart of the cavern among the stalagmites and stalactites, a feature not normally associated with the subterranean recesses of caves. Sections of the cavern’s ceiling had eroded away over millennia and collapsed, becoming gigantic windows that allowed columns of sunlight to penetrate into the darkness, illuminating a huge section of the cave and allowing ancient trees up to 30 m high (100 feet) to thrive here. This lush vegetation that blanketed the cave floor thrummed with life, hosting a plethora of wildlife from the outside world, including insects, rare birds such as the chestnut-necklaced partridge and the short-tailed scimitar babbler, snakes, lizards, monkeys, bats, flying foxes, and numerous species of butterfly, as well as an unknown number of as yet undiscovered new species.

Currently, Son Doong cave is recognized as being the world’s largest cave by far, much larger than the previous title holder, Malaysia’s Deer Cave. The main cavern is so large that it has its own climate, and clouds have even been known to form within it. It is massive enough to house an entire city block, high enough to hold 40 story high skyscrapers, and those who have been here describe being truly humbled by the sheer scale of this place.
The lost world of Son Doong cave still has its mysteries, and much of the cave system remains unexplored. Perhaps one of the most exciting areas of further exploration lies in the prospect of finding new species of plants and animals here. The animals of the cave can generally be categorized into two types; those that live in the forested area and those that dwell in the inky black recesses of the enclosed areas. Already several new species have been discovered here, including several species of plant and insect, as well as a new type of gecko, a tree frog, and a striped hare. Since only a very few expeditions have attempted to catalog species within the cave, there are undoubtedly more to be found. There have been several species that have been spotted that have not been identified as of yet, including a possibly new type of monkey, and mysterious creatures have been seen skittering through cave passages and even swimming through the river and lake here. One of the only scientists to have studied the dark interior passages of the cave, German biologist Anette Becher, described spotting a myriad of as yet unknown fish, insects, and millipedes within the gloom, many of them albino and sightless. It seems that we are only beginning to scratch the surface of the biodiversity that may lie here waiting to be discovered.

Other mysteries of Son Doong cave include the source of the underground river that runs through the cave and an only recently discovered side cave that is full of rare and undescribed fossils, many of them very large and some of them dated as being around 300 million years old. The original team to explore Son Doong has plans to launch another extensive expedition in order to further investigate the many mysteries of the caves.
In 2013, the first steps towards opening the lost world of Son Doong began when the tour company Oxalis began offering adventurous souls the chance to spend several days camping and exploring within the cave’s massive interior. The first expeditions are pilot tours, with the company planning to expand the tours in the future. The excursions are not for the faint of heart. In order to reach the cave, one must trek through remote jungle wilderness to the entrance of the cave, upon which a several hundred foot sheer vertical drop awaits. Only after after rappelling down the perilous face of the cliff will one finally be able to look upon this vast, mysterious world. Those who have seen the cave say that the sheer scale of the it is hard to comprehend without seeing it in person, and that it is difficult to describe in words how humbling and awe inspiring the experience is.

With tours such as this underway and yet more to be planned, it seems that just as with other lost and hidden places of the world, the caves of Son Doong too will have there mysteries slowly peeled away for all to see. For now, though, it is still a place of wonder and awe, and is still largely unexplored. What lies here awaiting to be discovered in the gargantuan cave’s many dark passages and within the ancient trees of  its misty, sun pierced subterranean forests? There is much left to learn about this vast, lost cave world, and much exploration left to do before we even begin to fully understand this fascinating natural wonder. Son Doong has not given up all of its mysteries just yet.
The discovery of Son Doong also poses another question. What other lost places remain out there for us to find? It is exciting to think that right here on our own planet there may be whole new vast, alien realms, even new ecosystems, hidden away from us, waiting to be discovered. Or perhaps maybe they will never be discovered, and will remain untouched by human hands as they have for millions of years and will for millions more. Whatever the case may be, even as the modern world seems to become ever smaller, it appears that there are still surprises locked away within this planet of ours.

How to Digitally Record/Video a UFO sighting:


Como registar digitalmente ou gravar um vídeo de um avistamento de um UFO:




Stabilize the camera on a tripod. If there is no tripod, then set it on top of a stable, flat surface. If that is not possible lean against a wall to stabilize your body and prevent the camera from filming in a shaky, unsteady manner.

Estabilize a camera com um tripé. Se não tiver um tripé, então coloque-a em cima de uma superfície estável. Se não for possível, então encoste-se a uma parede para estabilizar o corpo e evitar que a camera registe de maneira tremida e instável.

Provide visual reference points for comparison. This includes the horizon, treetops, lampposts, houses, and geographical landmarks (i.e., Horsetooth Reservoir, Mt. Adams, etc.) Provide this in the video whenever is appropriate and doesn’t detract from what your focus is, the UFO.

Forneça pontos visuais de referência para comparação. Isso inclui o horizonte, cimo das árvores, postes de iluminação, pontos de referência geográficos (como o Reservatório de Horsetooth, Mone Adams, etc) Forneça esses pontos no vídeo sempre que for apropriado e não se distraia do que é o seu foco, o UFO/a Nave.

Narrate your videotape. Provide details of the date, time, location, and direction (N,S,E,W) you are looking in. Provide your observations on the weather, including approximate temperature, windspeed, any visible cloud cover or noticeable weather anomalies or events. Narrate on the shape, size, color, movements, approximate altitude of the UFO, etc and what it appears to be doing. Also include any unusual physical, psychological or emotional sensations you might have. Narrate any visual reference points on camera so they correlate with what the viewer will see, and thereby will be better able to understand.

Faça a narração do vídeo. Forneça pormenores sobre a data, hora, local e direcção (Norte, Sul, Este, Oeste) que está a observar. Faça observações sobre as condições atmosféricas, incluindo a temperatura aproximada, velocidade do vento, quantidade de nuvens, anomalias ou acontecimentos meteorológicos evidentes. Descreva a forma, o tamanho, a cor, os movimentos, a altitude aproximada onde se encontra o UFO/nave, etc e o que aparenta estar a fazer. Inclua também quaisquer aspectos pouco habituais de sensações físicas, psicológicas ou emocionais que possa ter. Faça a narração de todos os pontos de referência visual que o espectador irá ver e que, deste modo, será capaz de compreender melhor.

Be persistent and consistent. Return to the scene to videotape and record at this same location. If you have been successful once, the UFO sightings may be occurring in this region regularly, perhaps for specific reasons unknown, and you may be successful again. You may also wish to return to the same location at a different time of day (daylight hours) for better orientation and reference. Film just a minute or two under “normal” circumstances for comparison. Write down what you remember immediately after. As soon as you are done recording the experience/event, immediately write down your impressions, memories, thoughts, emotions, etc. so it is on the record in writing. If there were other witnesses, have them independently record their own impressions, thoughts, etc. Include in this exercise any drawings, sketches, or diagrams. Make sure you date and sign your documentation.

Seja persistente e não contraditório. Volte ao local da cena e registe o mesmo local. Se foi bem sucedido uma vez, pode ser que nessa região ocorram avistamentos de UFOs/naves com regularidade, talvez por razões específicas desconhecidas, e talvez possa ser novamente bem sucedido. Pode também desejar voltar ao mesmo lugar a horas diferentes do dia (durante as horas de luz)para ter uma orientação e referência melhor. Filme apenas um ,inuto ou dois em circunstâncias “normais” para ter um termo de comparação. Escreva tudo o que viu imediatamente após o acontecimento. Logo após ter feito o registo da experiência/acontecimento, escreva imediatamente as impressões, memórias, pensamentos, emoções, etc para que fiquem registadas por escrito. Se houver outras testemunhas, peça-lhes para registar independentemente as suas próprias impressões, pensamentos, etc. Inclua quaisquer desenhos, esbolos, diagramas. Certifique-se que data e assina o seu documento/testemunho.

Always be prepared. Have a digital camera or better yet a video camera with you, charged and ready to go, at all times. Make sure you know how to use your camera (and your cell phone video/photo camera) quickly and properly. These events can occur suddenly, unexpectedly, and often quite randomly, so you will need to be prepared.

Esteja sempre preparado, Tenha sempre uma camera digital, melhor ainda, uma camera vídeo consigo, carregada e pronta a usar sempre que necessário. Certifique-se que sabe como lidar com a sua camera (ou com o seu celular/camera fotográfica) rápida e adequadamente. Esses acontecimentos podem acontecer súbita e inesperadamente e, por vezes, acidentalmente, por isso, necessita estar preparado.

Look up. Be prepared. Report. Share.

Olhe para cima, Esteja preparado, Relate, Partilhe.
