A Weekend at the Lake
Part of my Tibet trip was spending the weekend at the lake; Lake Nam Drop. Snuggled within a high mountain pass, Nam Drop is located just Southwest of Tibet's capital city, Lhasa. The Lake's altitude is about 4,700 meters up (sorry I don't know the conversion to feet), but it was really high. During our two nights at the lake, we slept in tents and dinned in a large amry-style mess tent.
The scenery around the lake, with it's jagged mountain vistas, clear aqua-blue water, and near to earth clouds will always be engrained in my memory as one of the most beautiful sights I've ever seen. 
Night at the lake was also amazing. The altitude combined with very little pollution made for incredible star gazing. The moon was so bright i could make shadow puppets on the ground. Stars were everywhere in the sky, and I could catch glimpses of shooting stars every ten or fifteen minutes. It was amazing.
Of course, at that high it was pretty stinking cold when the sun went down. Usually, by about 9:00pm the temperature had generally fallen to 20 degrees and the windchill was below zero. But to keep us warm, we lit campfires both nights. Of course, keep in mind that the Tibetan plateau is a high altitude desert with little or no foliage in most areas. So what did we make the fires out of you ask? Dried Yak manure.
The fire suprisingly didn't smell bad, but if the smoke got in your lungs you felt like they developed cancer on the spot. Lesson learned; if you smoke quit now, you don't want to ever feel like that for more than a few seconds at a time.
After the fire would burn out, we'd retreat to our tents where we slept with inside a mummy-bag with two blankets on top of us. 
Isn't it cute?
Certainly a weekend I'll never forget.
