Lechuguilla Caves, New Mexico, USA
I started watching the BBC series of Planet Earth and I began with the episode on Caves.
Since my childhood days, I had a very keen interest in geology – movies like Volcano intrigued me, I’d read lots on seismology and volcano-logy and I even used to say I want one of these. A particular fascination was with rocks and especially, stalactites and stalagmites.
Yesterday afternoon, with nothing in particular to do, I downloaded this series from our LAN and lo! was I captivated! The picture you see here is one of the most beautiful caves -on- no, below the surface of the earth. They extend miles after miles, a hidden network of hidden tunnels formed by the wrath-like eroding power of water and in the case of Lechuguilla and Kap-Kutan caves in Turkmenistan, the deathly and mysterious dissolving nature of sulphuric acid. There are unseemly formations of the base substance, limestone transformed to gypsum, aragonite amongst other forms.
While most caves are slushy and damp with water-ways through them, these caves only have these still pools of water – though acidic.
With no light ever entering these dark crevices, it is amazing to find bacteria that actually survive on the rock itself.
Underground caves in the Central American region once sustained the Maya Civilisation in Yucatan – there are no rivers in the area – because they are now flooded. They are termed as sink holes, the only source of freshwater in a river-less land.
Someday I’d like to go to these caves and witness these miracles of nature for myself.
ps : BBC Planet Earth series – highly recommended
