Seven Years in Tibet :
On The Move-6For the last time for years we camped in a wood. The next night we marched up the valley and soon were far above the tree line. We knew the mountain path well from our excursions, and our feeble lantern did its job. Still, occasionally we did get off the track. We had to be very careful in crossing the narrow wooden bridges over the river. They were glazed over with ice and we had to balance ourselves like tightrope walkers. We made good progress, though each of us was carrying a weight of nearly ninety pounds. By day we always found good scheduled spots to rest in, but camping in that temperature was too cold for pleasure.
