In the winter of 2003, Srijit Dasgupta and I were making our way to Kala Pattar and Everest Base Camp. It was bright and sunny as we left Pangboche after lunch but by the time we reached the small pass above Pheriche village, the weather had turned. Ominous grey clouds scudded across the sky and the wind howled, tearing at the prayer flags. We rushed down to take shelter in a lodge in Pheriche. It snowed for the next 48 hours and we stayed inside, sheltered from the wind and watching the snow level rising every moment. A cold white blanket had descended over the Khumbu nothing moved, nothing stirred. It was eerie as though all life had stopped no one came and no one passed by, not even yaks. On the third day the snow stopped and we stepped out into a white world, bright sun and an azure blue sky with no trail in any direction. The frozen plants emerged delicately above their white mantle, hard and sharp with backlit sun. This white wonderland was proving too difficult for me the cold high mountains too dazzling even to look at so I decided to shoot close ups. Rocks with icy patterns, streams frozen in myriad textures, and stone chortens almost submerged in the snow. Suddenly a herd of yaks appeared, descending surefooted from the pass. The herdsmen were coaxing them on from behind with yodelling calls. They were headed to Lobuche and we decided to join them. From a featureless white world we now had a path to follow, a miracle caused by these great beasts of burden, the backbone of life in the high Himalaya.
