Photo by @shonephoto (Robbie Shone) // This stalagmite found inside Lechuguilla (cave) in Carlsbad Caverns National Park has formed over hundreds of thousands of years as drip waters fall to the floor, de-gas carbon dioxide, and deposit calcium carbonate layer by layer. Later on, the chemistry of the drip waters has changed, and instead of calcium carbonate being deposited, it has been dissolved, revealing the internal structure of the stalagmite. The walls of the stalagmite have become so thin that it is possible to shine a light through them. One of the many fascinating formations from Lechuguilla, which is featured in the next episode (Genesis) of the Nat Geo Channels ‘One Strange Rock’. #OneStrangeRock
