Giant sinkholes discovered containing untouched ancient forests

Story by Harriet Brewis • 2mo •
3 min read

Most of us associate sinkholes with frightening abysses, but in China, they’re considered “heavenly” for good reason. Far from being mouths of doom, a number of these have been discovered containing pristine ancient forests.

Most recently, in August 2024, cave explorers stumbled upon one of these giant holes, which experts said likely contained species of small animals that were unknown to science.

This extraordinary hole reportedly measures a whopping 300 metres (1,000 feet) in length, 150 metres (500 feet) in width and is more than 190 metres (630 feet deep). It is located in China’s southwestern karst landscape and is now one of 30 such holes known as “tiankeng” – which translates as “heavenly pits” – in the region.

The reason for the trenches’ otherworldly name is that they are some of the last-remaining natural refuges for ancient forests and are home to species unseen anywhere else in the world.

Please check this link to "google images" for many views of these Chinese tiankengs. They are amazing, and some of the links are connected to videos, as well:

You've probably noticed huge sinkholes are opening in Siberia, as well, due to global warming and the thawing of the tundra. Some of them are enormous, already. Looks as if this will be happening there.

Anyone else a bit annoyed by the synthetic voice on the youtube video?

God we are a nuisance species..

https://www.bbc.com/news/articles/c8697gqwyx6o

But there are concerns that tourism revenue could override the demands of scientific research.

About 50km from Ping’e, developers have built what they say is the highest viewing platform, which overlooks Dashiwei, the second-deepest sinkhole in the world. Tourists can peer 500m down into this particular “heavenly pit”.

“We should better protect such habitats,” says Dr Lina Shen, a leading sinkhole researcher based in China. “Sinkholes are paradises for many rare and endangered plant species. We are continuing to make new discoveries.”
By studying sinkholes, scientists also hope to find out how the Earth has changed over tens of thousands of years, and better understand the impact of climate change. At least one sinkhole in Guangxi has already been closed to tourists to protect unique orchid varieties.


Tourism is one of the most vile and destructive industries out there.

Chris Ketcham has written about it:

https://www.christopherketcham.com/eat-pray-pollute-on-the-needed-death-of-tourism/

It’s the culmination of years of exploitation and maltreatment, said writer Chris Christou, who produces “The End of Tourism” podcast. “In the last decade, especially in southern Europe,” Christou told me in an email, “we’ve seen local movements sprout and mobilize —typically from the grassroots Left — against the relentless conversion of home into a veritable theme park for ignorant foreigners.” Christou has documented the industry’s long train of offenses: environmental degradation; cultural appropriation and what he calls petrification (“the stasis or congealing of culture’s flow or growth”); spiraling economic inequality; the Airbnbization of dwelling; gentrification and displacement; corporate and government nepotism; the revolving door of corruption between tourism bureaus and industry; the rise of an extremely precarious labor force; and, not least, “the spectacled surveillance of place that effectively turns home, for local residents, into a turnstile Disneyland.”

If you love a place,” a retired ranger who worked at the Grand Canyon once told me, “don’t make it a national park.” On a typical visit to Grand Canyon National Park during the summer, you will first find yourself stuck in traffic backed up a mile or more from the entrances, the idling cars belching fumes. When at last you snag a parking spot and, with everyone else, debouch onto the hiking trails, you’ll find food wrappers, toilet paper, discarded clothing, and plastic bottles, courtesy of the previous blast of visitors. You will experience, alongside the glorious vistas, your fair share of the stink of human feces and, at choice spots for taking a piss, the piercing ammonia perfume of urea.

... in the week between Christmas of '75 and New Year's, which is probably why we were spared any scatological encounters. Celebrated New Year's Eve at Phantom Ranch, then hiked up Bright Angel Trail to the rim. Wore my sneakers like slippers, having burned my well- broken in boots for giving me blisters on the blisters my blisters had. Luggin' 50-odd pounds of winter gear was tough on the tootsies.

And Coleridge poem about Xanadu.

To stand within the Pleasure Dome
Decreed by Kublai Khan
To taste anew the fruits of life
The last immortal man

To find the sacred river Alph
To walk the caves of ice
For I will dine on honeydew
And drink the milk of paradise

As one who taught "Kubla Khan" for decades, appreciate any popular cultural allusions!

Neil Peart of Rush fame was inspired by Coleridge's poem when he wrote Xanadu back in the 70's.

Otherwise they will become tourist destinations and will be quickly destroyed.

I read a few months ago a little about these sinkholes, but it’s nice to be reminded, and take advantage of an opportunity to learn more about them!

I don't understand how those rock formations can result in such stunningly well-formed cylinders.
No rift or earthquake-like activity could produce such a thing.
I vote space lasers, but I'm weird!
