"After stopping at the monastery for few minutes, we trekked down to the valley and then started the slow climb towards Langza. During the walk through the entire stretch, we saw several hundreds of fossils, which looked almost like a work of art. Considered to be one of the most fossiliferous regions of the world, Spiti Valley tells us the story behind the trilobites and ammonites that were formed after the collision of Indo-Eurasian sub-continent.
While observing the beauty of the fossils lying in the streams and nearby valleys, one can't just stop for a second and think, 'Oh my, how could I believe that this entire mountain stretch that we stand now at around 4,300 MSL was part of Tethys sea some 200 million years before!' Geologists say that the larger continent of Pangea started to split into various land masses as a result of which, the two main land masses of Indian and Eurasian subcontinent started depositing large amounts of sediments into Tethys. Further collision over the period of time helped form the present Himalayas and those marine animals that we see now as fossils including the ammonites used to be present in the Tethys at that time.
While we stood there breathless thinking about the entire process, we heard stories of local boys who collect the fossils to sell it to tourists from different parts of the world. What should be priceless is sold for as cheap as less than a US dollar! It seems there are tourists who proudly announce that this is their 3rd or 4th visit to collect fossils in the last couple of years!
The story wasn't much different even in the small town of Kaza where you can see the fossils kept amongst the antiques on sale for a dollar or two! It seems there are discussions of setting up a geological museum so that at least what is remaining can be preserved. With an un-patrolled area as vast as Spiti valley and irresponsible tourists searching for fossils, it makes more sense to have a museum where these fossils can be displayed.
It will be sad if this happens as I personally prefer to see these fossils in its natural ambiance where responsible travellers and the locals understand the importance of the existence of these fossils to the evolution of the entire mankind and the earth itself". © GP
