During our Bhabha Pin Trek in late September this year, I witnessed something for the first time in my travels in the Himalayas – a stream that could be heard loud and clear, but couldn’t be seen. I had already heard about the term “Subterranean River” while I was reading about the Bhabha Pass trek and naturally I was excited to see this phenomenon with my own eyes. In fact, I had imagined that it would be a flat ground with the water running through some channel just underneath the surface. However, on reaching the actual spot, I realised that the stream was buried under a huge pile of rocks and boulders, making its way by eating away through the base of the gulley. But the sight and sounds were mesmerising nonetheless – I tried to peek and see through the gaps in the rocks but Mother Nature teased me with yet another of her marvels, showing me everything that there was, and yet hiding it enough to keep me hooked on and remember this for the rest of my life. And such things are what keep attracting me to travel more in the high mountains – there’s always something new around the corner, waiting to put one in awe.
