Spiti's Langza village steps into India’s geo-heritage map

High in the cold desert of Lahaul-Spiti, Langza village has long guarded secrets from a vanished ocean. Now, at 4,400 metres above sea level, this stark Himalayan landscape has formally entered geological map of India. On March 6, the GSI declared Langza a geo-heritage site of national importance, recognising a fossil record that dates back roughly 150 million years.
