The night has brought silent, blanketing snow, transforming the village of Chitkul into spun sugar houses, their slate roofs thick with puffs of, well, icing. Blue pines and cedars look utterly Christmassy &mdash jolts of light wind blowing the fresh snow off their evergreen foliage. The sky is blue the broad lay of the valley a wintry white. I walk on a level path lined with candyfloss bushes, with round snowballs crowning their thorny edges. The valley to the east upholds an expansive view of snow-clad mountains across which lies Uttarakhand and Tibet depending on which direction one is looking at. It is mid April and the valley should be blooming into spring, yet it wears its winter cloak. I am on a walk to Nagasthi, the last ITBP post in the Sangla valley of Kinnaur from where civilians can go no further. The walk is level, the landscape surreal and pretty.
