|[Note Guidelines] Photographer's Note|
|The landscape belongs to Pangong Tso (Tso in ladakhi language means lake). The excess of natural blue color seen at this altitude (14,000 feet ASL) has been desaturated by me to give it a different look. |
The Pangong Tso had started melting from shore in the month of April, as one could see broken layer of thinning ice visible in the left corner of the photograph with gushing water currents. I was amused as to what causes water to create currents in otherwise looking static lake....!!!!
Reason: The water is most dense at temperatures near freezing. When water freezes, however, it expands, becoming less dense. If equal volumes of cold water (down to 4deg.C, 39.2deg.F) and hot water are compared, cold water weighs more than hot water. Differences in water density cause underwater currents. Cold, dense water sinks to deep levels in the lake. Warm, less dense water moves in to replace it near the surface. Differences in density of water due to different amounts of salt also cause underwater currents in static looking lake.

Good to see another picture of one of most beautifull lakes I've ever seen. Another superb landscape with lots of water and great looking mountains on horizon. Very interesting note about water movement.
I didn't even read it...I knew it was called "Icy Silence". I wonder if the quiet up there is like it is in my wilderness...They say and I know that this quiet is what I know as almost a deafening quiet...more than the quietest one can imagine...unless a breeze perhaps or some small wave....but other than that..lets say at night when your ears are moist attuned at waking in the middle of the night everything is so clear and still..is there any noise at all? A hum lets say of the worlds frequency as it turns or something coming in from outside of the atmosphere? I would like to know.
excellent landscape shot with a fine POV, i love the effect
