Photographer's Note

I know it sounds a bit strange: first I mentioned the glacier calving and now comes the glacier milk.

Am I serious? Yes.

I heard this expression for the first time from emka.

Created in the calving process icebergs melt, producing a water that has a very specific color. Most lakes and rivers which I had a chance to see in Patagonia had a distinct green color. The intensity depended on the available light but without a doubt it was green. The explanation is very simple: the water contains tiny particles of rock.

On the web page of the US Geological Survey I found following explanation:
Rock Flour - fine-grained, silt-size sediment formed by the mechanical erosion of bedrock at the base and sides of a glacier by moving ice. When it enters a stream, it turns the stream's color brown, gray, iridescent blue-green, or milky white. Also called Glacier Flour or Glacier Milk.

I have some photos where the color is much more pronounced yet somehow the title seemed very suitable here.

This photo was taken during the hike to Laguna Torres, with trailhead in El Chalten (Southern Patagonia, Argentina). After 3 hours hike you arrive at Laguna Torres across which you have amazing view of Cerro Torre. The river which you see here flows out of the Laguna Torre, I was not able to find its name.
