"Noted Italian geologist and cave explorer Francesco Sauro, who has led successful expeditions to one of the world’s oldest cave systems in Venezuela’s Tepui mountains, is gearing up to explore the “lost world” in India’s Meghalaya, which harbours some of the longest and deepest cave systems in the world.

Sauro, a speleologist, who has close to 20 years of caving experience, has participated in studying these hidden environments around the world, of which six expeditions have been to the Tepuis, the table top mountains of South America. Speleology is the scientific study of caves.

The 2014 Rolex Young Laureate recipient in exploration for his “exploration of ancient quartzite caves in the table-top mountains of South America”, now hopes to delve into the magnificent cave systems of Meghalaya, home to Krem Liat Prah, the longest natural cave in India. Most of them are limestone and sandstone caves."

"Descent 258 is now available! As ever, Newsdesk will bring you up to date with news at home and abroad. A new world depth record has been set in a cave in the Western Caucasus in Georgia. The latest volume in the hugely popular Northern Caves series is now available. Two stunning new calendars are available to choose from, Wild Places is again stocking the Underground Worlds calendar and there is one from Speleo Projects, as well. There’s more information about the special event being hosted at the Royal Geographical society in London from 1st to 4th on December entitled A Golden Age of British Cave Exploration. A warning is given about possible plagiarism on a new cave-related site, Start Caving; and another warning is given of the dangers posed to cavers by tick-borne diseases. On a sad note, Descent notes the death of Bryan “Scoff” Schofield, known and loved by many. But remember that this is just a short sample of the range of items covered by Newsdesk so do take a look for yourselves"

"Geologists don’t fully understand the process of erosion that created the unique system of caves in Venezuela’s Tepui mountains. These table-topped landmasses were formed out of quartzite, one of the hardest minerals in existence, and yet they contain a magnificent network of caves. That means they’re old. Very old. Cave explorer Francesco Sauro (TED Talk: Deep under the Earth’s surface, discovering beauty and science) figures they’ve been hundreds of millions of years in the making — and they’re quite likely the oldest caves we can explore on Earth. Sauro led one of the deepest expeditions into the cave system in 2014; here are a few images from his trip, which he describes as a leap back in time."

Kartlegging / Cave Surveying – the next steps?
« Nyeste innlegg av Rolf 27.09.2017 15:39 »
"The backbone of cave surveying is the data, in other words the numbers. We spend many hours collecting them, and some time building up pictures around the numbers. This means that as computers became a home item, cave surveyors rapidly adopted them to carry the burden of the tedious after-caving task of crunching the numbers. In recent years, we have also moved this technology into the cave and with it the surveying has continued to improve. However, getting in at the start of something generally means that most of the things you do have to be developed from scratch.


"Surveying is now changing rapidly, or certainly looks like it is about to. 3D laser scanning is growing and photogrammetry or image from motion is getting there, together with all the additional data that can be collected when surveying, like the photos, that now number thousands on every expedition."

"Indiana University has suspended its student spelunking club pending an investigation into how a freshman was locked inside a cave for 60 hours.

University officials announced Monday that the Office of Student Conduct is conducting an investigation into how 19-year-old Lukas Cavar became trapped inside Sullivan Cave with no food or fresh water, The Herald-Times reported ."

“I was very confused and pretty scared,” Lukas Cavar told the Indiana Daily Student. “It took me a little while to wrangle my emotions and sort of approach things analytically, sensibly, to come up with a game plan to survive.”

Cavar, a 19-year-old physics major, was rescued late Tuesday night after the president of the Caving Club realized that the group had forgotten the freshman at the end of Sunday’s trip to Sullivan Cave in Southern Indiana. The club’s leaders raced to the cave and unlocked the entrance gate — the same gate one of them had locked on their way out, trapping Cavar.

“You could tell they were pretty shaken up,” he said. “They did near kill me. I can’t imagine what kind of guilt they felt.”

As soon as the club leaders freed the freshman, he devoured a bowl of pasta and a leftover Big Mac one of the rescuers brought to the scene.

“Probably the best food I’ve had in my life,” he said.

As of Friday, unanswered questions lingered. The club leaders, who asked not to be named, refused to explain exactly how Cavar was left behind. "
