Grotte- og gruvenyheter / Explore Hang Son Doong, the world's largest cave
« Nyeste innlegg av Rolf 16.08.2017 10:06 »
Hang Son Dong grotten i Vietnam er tidligere omtalt en rekke steder på forumet.

CNN har en omtale av grotta:

"Located in the heart of the UNESCO-listed Phong Nha-Ke Bang National Park in Vietnam's Quang Binh province, Hang Son Doong is one of the most captivating adventures that can be experienced in Southeast Asia.
More people have stood on the summit of Mount Everest than have witnessed the surreal beauty inside these enormous chambers. Translated as Mountain River Cave, it was first discovered in 1990 by Ho Khanh, a local farmer who was seeking shelter from a passing storm in the jungle.
He noticed clouds and the sound of an underground river gushing from a large hole in the limestone, and reported his findings to the British Caving Research Association (BCRA), who were stationed in Phong Nha at the time.
Unfortunately Ho Khanh lost his bearings during his return, and the exact location of the cave remained lost for 18 years. In 2008 while hunting for food he stumbled across the entrance again, and returned the following year with Howard and Deb Limbert from the BCRA."

Grotte- og gruvenyheter / Humans were in Indonesia more than 63,000 years ago

"In the Padang Highlands of western Sumatra, a large island in Indonesia, there is a small cave called Lida Ajer that has long offered up clues about human history. Dutch paleoanthropologist Eugene Dubois first excavated the cave before 1890, and Lida Ajer has turned up plenty of preserved animal remains since, including teeth that were identified as human in 1948.

It’s only now that the cave has been carefully and thoroughly dated, providing a new line of evidence that our species was in the region more than 60,000 years ago. That’s 20,000 years older than the previous oldest skeletal evidence of humans in the area. But these new dates line up with existing genetic evidence, as well as with reconstructions of the climate and sea levels at the time."

" Tuckaleechee Caverns is proud of its cave, boasting among other things that it has the tallest subterranean waterfall in the eastern United States.

It's also got a tooth it's pleased to show off. A mastodon's tooth, to be specific.

On Tuesday, the Townsend attraction began displaying the tooth, discovered last year by guide Lauren Webb near a cavern stream.

"She was looking around in the creek for quartz and she said she saw this strange-looking piece of quartz,"  cave manager Benjamin Vananda said Tuesday.

"I picked it up, and I knew right away it wasn't a rock," said Webb."

"A teenage boy had to be rescued from caves after getting wedged between two pieces of rock when he tried to squeeze through using a move used by action hero Superman.

The 16-year-old boy was part of an outward bound group exploring the boulder chamber in the Goatchurch Cavern at Burrington Coombe.

Rather than walk around the two pieces of rock – known as Superman Squeeze – the teen decided he would try and go through it instead.

But he became firmly wedged between the two pieces of rock.

The rocks are known as the Superman Squeeze as cavers have to take a position used by the action hero when he flies - one arm in front and one arm behind - to get through.

The youngster, who was on an expedition based out of the outward bound centre at Charterhouse on The Mendips, was stuck for more than three hours."

"When Nazi forces advanced towards the Ukrainian village of Korolówka in 1943, Etcia Goldberg was 36 years old, a widowe
of three children. As the armies drew closer, Etcia took matters into her own hands, leading a group of 37 Jews to a small cave known as Priest’s Grotto.

There, they hid underground, living by candlelight and surviving off scavenged food, for nearly a year before they emerged.

The story the Ukranian Jews who survived the war in a cave is well-documented. Now, a new book is revealing Goldberg’s role for the first time.

344 Days Underground is the self-published novelization of Etcia’s life and her time in the cave, written by her grandson, Valeriy Gritsiv, a former endocrinologist and adoption coordinator. An independent spelunker named Christos Nicola had previously spent years researching Priest’s Grotto, culminating in a National Geographic article, a book, and a documentary on the subject. However, Gritsiv felt that his grandmother never got the credit she deserved. 344 Days Underground is his first book. Gritsiv, whose native language is Ukrainian, worked with a ghost writer to bring her story to light."

Grotte- og gruvenyheter / Search on for missing Sagada guide
« Nyeste innlegg av Rolf 22.07.2017 22:28 »
"Caving activities inside the famous Sagada Caves in Mountain Province were suspended by town officials after a tour guide went missing inside the still unexplored Victoria tunnel at Maduto, Amkileng. Authorities identified the missing tour guide as Roderick Malecdan, a native of Sagada, who was believed to have been flushed inside a deep portion of the cave. Initial police investigation revealed seven tour guides allegedly entered and explore Victoria cave in preparation for the visit of tourists when a huge volume of water triggered by the early afternoon rains suddenly entered the tunnel and flushed them inside. Four tour guides were able to come out of the cave while two others were rescued by responding rescuers. Rescuers were able to identify the area where the missing tourist guide was and they are expected to scour the area once the water drop to a manageable level inside the tunnel."

Grotte- og gruvenyheter / The Man Who Blew The Door Off The Microbial World
« Nyeste innlegg av Rolf 20.07.2017 20:22 »
"A few years before Norm Pace revolutionized the study of life on Earth, he almost lost his own life.

He’s best known as a microbiologist, but he’s also a die-hard spelunker. In the 1970s, he and a group of friends set out to explore a Mexican cave called Sumidero Yochib. It sits at the bottom of a massive sinkhole that doubles as a large drain; when it rains, a hundred square miles of water funnel into the entrance, turning it into a raging torrent. These waterfalls, combined with almost a dozen sheer drops, make Yochib one of the most dangerous caves in the world.

Pace learned that the hard way. During one of his expeditions into Yochib, the bolt that was holding Pace’s rope popped out. He fell, straight into the path of a waterfall. His companions tried to pull him up, but failed. They headed back to the surface, sure that they had just seen their friend die. But Pace was very much alive. He had used his helmet to create an air pocket, which allowed him to breathe amid the cascading water. Slowly, he climbed his way out. His friends were trying to work out how to recover his body, when said body walked up to them and calmly sat down."


Grotte- og gruvenyheter / Researchers Extract Human DNA From Cave Sediments

"Researchers at the Max Planck Institute in Leipzig, Germany have developed a new method of retrieving hominin DNA from sediments, even in the absence of skeletal remains.
In comparison with the amount of human-made tools and other artefacts available, skeletal remains of ancient humans and their ancestors are comparatively scarce and where such remains do exist, the recovery of viable DNA has long been the Holy Grail of many researchers.

Researchers at the Max Planck Institute have been looking into new ways of obtaining ancient human DNA and have turned their attention to sediment samples collected at seven archaeological sites."

Grotte- og gruvenyheter / Two Rescues at Box Mines, Wiltshire
« Nyeste innlegg av Rolf 11.07.2017 16:57 »
"Firefighters and cave rescuers have had to attend Box Mines near Corsham, Wiltshire, twice in three days to assist parties in trouble underground. On 2 July 2017, Corsham Fire and Rescue assisted a group of three who had entered the mines via Back Door entrance and made their way to Jack’s Working entrance where a recently installed grill blocked their exit. They were able to use their mobile phones to call for help and a small team from Mendip Cave Rescue led them out through a nearby entrance.

Three days later, in an almost identical incident, a party of seven youths from Bristol entered Box Quarry via the Back Door entrance at about 11pm on 4 July 2017. They made their way to Jack’s Working entrance but found this had been grilled in the couple of weeks since their last visit there. They were unwilling to return to the Back Door to exit as the torches on their mobile phones were running low on battery."
