Massive Cave Discovered in Vietnam

by Kraig Becker on

A massive cave discovered in a remote region of Vietnam has been explored for the first time, and is now believed to be amongst the largest in the world. With its main chamber stretching nearly 500 feet in length, and soaring to an unbelievable 650 feet in height.

The cavern is called Hang Son Doong, which means “mountain river cave” in Vietnamese, and was first discovered back in 1991, but was not explored until recently, when a 13-man spelunking team from the U.K. went inside for the first time. The team used a high tech laser to plumb the length and depth of the cavern, and based on preliminary results, they now believe that the cave reaches a height that is at least twice as tall as the largest previously known cave.

The expedition trekked six hours through the jungle to reach the cavern, then spent five days exploring it. In order to reach the massive main chamber. they had to rappel down into a side chamber, cross two underground rivers, and then negotiate several passages. Their cursory survey revealed that the cave system is more than 4 miles in length, but the team believes that there is much more yet to be discovered, and they’ll return later in the year to more thoroughly investigate its depths.

While this cave is genuinely an amazing find, and the height of its main chamber may be the largest yet discovered, it pales in comparison to a cave called Gua Nasib Bagus in Malayasia, whose main chamber streches 2300 feet in length. The king of caves remains Mammoth Cave system in Kentucky however, as it streches at least 365 miles in length, with more passages being discovered all the time.

In the Corner of the World – Cold and glowing vs. hot and bubbly

by Jeremy Kressmann on

Over the next few weeks here at Gadling, we’ll be bringing you updates from our recent travels across New Zealand – in the process, we hope to offer a range of perspectives about what visiting this truly unique and fascinating country is all about. You can read previous entries HERE.

You’re standing on the edge of a ledge. Covered head-to-toe in a neoprene wetsuit, purple short-shorts and giant white rubber galoshes, and holding a large inner tube. You’re contemplating a jump into the frigid waters that slosh noisily just below. It’s pitch black, but your headlamp punches temporary holes in the emptiness, providing glimpses of other victims shouting and flailing wildly beneath you. A man taps you on the arm and pushes you forward – you hesitate, but there’s nothing to do but turn around and jump, plummeting ass-first towards the numbingly cold water beneath you, awaiting the inevitability of a painful impact.

This certainly wasn’t how I had pictured my day unfolding when it began. We were headed 2 hours south from Auckland, driving towards Waitomo, a village that is home to one of the largest complexes of underground caves in New Zealand. Caving is highly popular attraction in New Zealand, and the underground spaces like those found at Waitomo boast almost 400,000 visitors each year.

We had also heard about a peculiar Waitomo Cave phenomenon known as “Glowworms” – a unique species of bioluminescent insect that emits an eerie light in order to attract its prey. Glowing insects and cave exploring? Our interest was piqued – we wanted to see these strange creatures up and close and personal for ourselves. But how exactly does one go from a casual curiosity in glowing cave bugs to standing shivering, wearing a wetsuit in a pitch black cave? And how did we plan to warm ourselves up afterwards? Keep clicking below to see what happened.
Visitors to Waitomo caves have a huge range of options for viewing these amazing natural wonders and the strange wildlife like glow worms that live within them. Trips to Waitomo Caves range from more casual walking tours along guided underground paths to full-on spelunking and cave rafting expeditions.

Though a leisurely cave walk sounded fun, this was New Zealand after all – frequently cited as the home of “extreme sports.” We wanted a more “hands-on” experience so we opted for an underwater tubing trip which would take us on water voyage through the inner workings of the one of the caves. After suiting up in what is perhaps the stupidest outfit I’ve ever worn in my entire life (pictured left), we were ready to enter the caves.

As we entered the first narrow tunnel, icy cold water up to our waists, I began to wonder what I had gotten my claustrophobic self into – but the scenery quickly changed. After jumping through a few small waterfall pools, the ceiling soon opened upwards, revealing a massive underground cavern big enough to hold a cathedral and a meandering underground stream. Above us lay a miniature Milky Way of twinkling lights – a constellation of glowworm insects silently advertising for victims. We hopped aboard our inner tubes and floated lazily down the cave’s river as we gazed up at the artificial light show performance above us. Still under the hypnotic visual spell of such a strange sight, we soon emerged back into the midday light, none the worse for the wear but soaking wet and exhilarated by our recent adventure.

After all the freezing water from the morning’s caving activities, it was time to warm up and relax. We headed 150 kilometers east towards Rotorua, a city that lies on the edge of one of New Zealand’s more active geothermal hotspots. In addition to geysers and mud pools, Rotorua is also an outdoor activities destination offering the chance to mountain bike, raft, fish and swim. But a morning of cave-exploring had just about done us in at this point – we were ready to just hang out. We stopped by the Polynesian Spa to take a soak in their naturally heated thermal waters, renting a private pool with a view of Lake Rotorua for 30 minutes.

As we immersed ourselves in the warm embrace of the nearly 100 degree water, the starry night sky above us punctuated by the Southern Cross, we had a chance to think back. Our day had taken us across two huge extremes in temperature. From a morning sloshing through knee-deep freezing water, looking up at ghostly glowworms to a heated hot-spring pool and starlit New Zealand sky. Going from cold to hot – it was just the kind of extreme transition we’d come to find down in New Zealand, the corner of the world.

Diggers of the Underground Planet: Exploring the mysteries beneath Moscow

by Neil Woodburn on

Far below the city streets, in the very bowels of Moscow, a ragtag group of modern-day troglodytes oversee the countless, eerie miles of subterranean tunnels and caves which crisscross their way through the Russian capital.

Most tourists are only aware of Moscow’s phenomenal metro system and limit their time underground to short trips between various stations. The metro, however, is just the tip of the iceberg, as they say.

Vadim Mikhailov (above) knows this because he heads up a group called the Diggers of the Underground Planet. The members don’t technically dig, but they do spend a great deal of their time with flashlight in hand, exploring the six to twelve layers of underground Moscow. Since organizing into a group in 1990, the Diggers have been mapping out the abandoned subway tunnels, sewer systems, drainage tunnels, bunkers, riverbeds, waterfalls, lakes, laboratories, torture chambers, mass graves and more. This 850-year old city has lots to hide.

Perhaps the most infamous underground secret is the private subway Stalin had built which reportedly runs to a number of locations including the Kremlin and even to the suburbs outside of Moscow where Stalin had his dacha. This metro is apparently still in operation and therefore a wise Mikhailov never comments on it.
Even more legendary is the 15th century library of Ivan the Terrible. The underground location of this invaluable collection of Byzantium books and scrolls has been lost to history and treasure seekers have been looking for it ever since. As you might imagine, this is the holy grail of Moscow’s underground and the Diggers are constantly searching for it.

Unfortunately, the Diggers do not conduct tours of the tunnels, although there have been reports of them considering this for the future. In the meantime, it’s probably not a good idea to explore the dark underground on your own. In addition to rats, mutated animals, human waste, corpses, and even discarded radioactive material, the Diggers have also come across satanic cults, armed men in uniforms, and members of the criminal underworld living and doing business underground. This is certainly not a place for amateurs.

Tunneling under universities becoming more difficult

by Neil Woodburn on

Many large American universities offer fascinating opportunities for urban exploration in the form of underground tunnels.

Although most students don’t know they even exist, those that do, tend to be infatuated with infiltrating their subterranean depths.

The tunnels were built to distribute water, wiring, and steam for heating, to the numerous buildings on campus. They’re dark, mysterious, and alluring–or so I’m told. I chickened out of exploring the six miles of tunnels on my campus because of the rumor that anyone caught inside would be immediately expelled from the university, no questions asked.

Those that did take the risk, however, report that it was rather easy to find a way in and move about undetected. This is no longer the case. According to an LA Times article by Tony Barboza, universities across the country, fearful of terrorist attacks and lawsuits from adventures gone bad, are tightening up tunnel access, sealing entrances, and installing security systems. In other words, if you try it today, you will get caught.

Dammit, one more college tradition killed off!

Scuba Dive and Play Tennis in a Cave

by Jamie Rhein on

We’ve written about how you can mail a postcard in a cave, stay the night in a volcano cave–or some other caves, bungy jump in a cave, paddle in a cave, and go to church in a cave. There’s a whole lot more you can do in a cave and I’m sure one of us have mentioned it, but these will do for now. Missouri is the place to go for even more cave fun. It’s not called The Cave State for nothing.

The reason Missouri has such cave wealth has something to do with mining. When you dig sand, limestone and lead from underground, huge caverns are the result. These left behind caverns make for terrific underground recreation facilities since the temperature stays constant year round regardless of what the weather is doing above ground.

Here’s what you can do in Missouri’s caves besides walking through them. You can:

And in the future, hopefully, you will be able to ice-skate and kayak at Crystal City Underground, once a sand mine.
