Starting our expedition from Uttarkashi's Bhojbasa, elevated at 3,800 metres, we experienced a biting 5-degree sub-zero temperature. I, my wife Ponni M Nath, and our logistics manager Yog Raj Thakur, set off towards Gaumukh at 8 am. My heart surged with a mix of happiness and excitement. The trek soon grew arduous, strewn with boulders and massive fallen rocks along the path. Manoeuvring through the moraine (scattered debris) proved the trickiest segment. The route had been smoother, but the past winter brought a surge of new rocks down the slope.
