Giant sinkholes discovered containing untouched ancient forests

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.

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.

I am always in awe of Mother Nature! 
TY for sharing, JudiLynn!
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!
