This was the most magnificent glacier-fed lake I had seen or have ever seen. It must have been at about 12,000 feet perhaps. The water was perfect. There are piles of prayer-stones on the side placed by passing Tibetans.
On the extreme left is Khaitan, and I am the first to his right.
(Within minutes of my posting this, a friend familiar with mountains identified this as Dudh Pokhri Lake at 15,000 ft and that the peak seen from the lakeside is Kothang. I was informed that a young man named S. Sinha of the Univ of North Carolina Computer Science Department has a lot of fine photos taken in 2004-2005 of the same region and route we had taken as schoolboys 37 years ago.)
