Photographer's Note

Hiking the Perito Moreno Glacier was definitely the highlight of our trip to Patagonia. The icescapes are simply beautiful and they are so hard to compare with anything I know from the everyday’s life. I have skied Alpine glaciers many times before, but this here was a completely new experience. It was like being in a whole different foreign world, which has its own mountains and rivers and other unknown structures.
Unfortunately for safety reasons we could not move freely on the glacier so I could not compose the photos as I would really like. Without the presence of people the icescapes seem strange. They look like snow on any hill anywhere in the world. Just when you have a scale marker you can imagine the size of this place and the structures present there. Therefore I have two more photos attached here as workshop. Workshop 1 shows same view with my wife posing in front of it. It will at least give you an idea about the size of this water puddle. Workshop 2 shows a different whole in the glacier along the trail. I took it together with my shoes so that again it gives some idea about the scale. The second one is obviously much smaller. To have a better idea about the vastness of this place please have a look at my previous upload from this hike.

I was tempted to use the pseudo HDR here but I decided not to do that. The colors are thus very natural. The day was rather grey but still the blue tones were very intense in places.

ABOUT THE BLUE COLOR
We have already had a discussion with emka about the origin of the blue color of the glacier. The discussion promted us to search for the correct answer and these are the answers which we came up with:

The blue color (of ice) is often wrongly attributed to Rayleigh scattering. Rather, ice is blue for the same reason water is blue: it is a result of an overtone of an oxygen-hydrogen (O-H) bond stretch in water which absorbs light at the red end of the visible spectrum.

From the surface, snow and ice present a uniformly white face. This is because almost all of the visible light striking the snow or ice surface is reflected back, without any preference for a single color within the visible spectrum.
The situation is different for light that is not reflected, but penetrates or is transmitted into the snow. As this light travels into the snow or ice, the ice grains scatter a large amount of light.
