What was your first reaction when you read the title? Is this guy talking about a Chinese movie on his list? Or maybe, it was : he has lost it after just five posts. Sadly, I am still sane and this is another awesome addition to The List.
Krem Liat Prah is the largest natural cave in India. It is situated in the Shnongrim Ridge of the Jaintia Hills district in the state of Meghalaya, northeast India. Currently being surveyed in the Abode of the Clouds Expedition, its length is approximately 25 kms and more is being added to that as connecting tunnels are discovered. It is carved out of limestone and contains some spectacular caverns, one of which is called the Aircraft Hangar. (Well, they must have named it that for a reason, no guesses why!)
And that's not it. Liat Prah is not the only cave in the area. There are around 150 other caves, not as large as Liat Prah but equally spectacular.
So, now that you are all in awe and amazed at the beauty and extent of the cave, let's get a little geological insight into it as well. How are these formed? And why here of all places? The reason is simple - I mentioned it before - limestone.
Limestone is a sedimentary rock composed primarily of calcium carbonate. CaCO3 is one mineral which dissolves so easily that I sometimes wonder how it even forms huge massive rock deposits! So, as groundwater makes its way through these rocks, it carves out a path and over a period of time enlarges them enough to create these marvels. And, sure enough, the Jaintia Hills, where these caves are found, are composed of limestones belonging to the Prang formation of the Sylhet Group. Massive, fossiliferous and grey, these limestones are from the Eocene Period (approximately 48 MYA to 34 MYA) and form a thick succession which is perfect for the formation of an underground network.
Going by the extra ordinary proportions of Krem Liat Prah, it is a surprise it has remained hidden for so long. Not anymore. Its wait in the shadows ends now. Time for some spelunking!
