[Note Guidelines] Photographer's Note
A few days ago Ram mentioned in his notes how hot it is in Riyad at the moment, so this posting is dedicated to him - to remind him of cooler climes!

The Perito Moreno Glacier is a glacier located in the Los Glaciares National Park in the south west of Santa Cruz province, Argentina. It is one of the most important tourist attractions in the Argentine Patagonia.

The 250 km² ice formation, of 30 km in length, is one of 48 glaciers fed by the Southern Patagonian Ice Field located in the Andes system shared with Chile. This icefield is the world's third largest reserve of fresh water and the largest icecap outside the polar regions.

Glacial motion is the motion of glaciers, which can be likened to rivers of ice. It has played an important role in sculpting many landscapes. Many lakes in mountainous areas and in high latitudes of the world occupy basins scoured out by glaciers. Glacial motion can be fast (up to 30 m/day, observed on Jakobshavns Isbrae in Greenland) or slow (0.5 m/day on small glaciers or in the center of ice sheets).

Glacier motion occurs from two processes, both driven by gravity: basal sliding and internal deformation. In the case of basal sliding, the entire glacier slides over its bed. This type of motion is enhanced if the bed is soft sediment, if the glacier bed is thawed and if meltwater is prevalent. A glacier that is frozen up to its bed does not experience basal sliding. Internal deformation, the second process, occurs when the weight of the ice causes the deformation of ice crystals. This takes place most readily near the glacier bed, where pressures are highest. There are glaciers that primarily move via sliding, and others that move almost entirely through deformation.

If a glacier's terminus moves forward faster than it melts, the net result is advance. Glacier retreat occurs when more material ablates from the terminus than is replenished by flow into that region.

DECLINING/MELTING ICE SHEETS
In polar regions glaciers do not move as fast as they are frozen to the bedrock – or were! Recent work in Greenland and the Antartic penisula has shown that higher temperatures have resulted in much more melting on the gacier’s surface – this water ponds up, finds it way, by means of crevasses, to the bottom of the glacier – then hey presto – the glacier has lubrication and starts to move quickly. This process resulted in the destruction of the Larsen Ice Shelf in Antarctica and is now happening rapidly in Greenland (and I live 1 inch above sea level)!!!

BY THE WAY
Glaciers/ice are not blue - they absorb the other wavelengths of light apart from the blue - those are reflected away - hence the glacier appears blue. Old ice contains less air, so reflects more light - so, the darker the blue, the older the ice.

This is a scanned slide.

Hi James,
This is exactly where I want to be right now :o) The colors of the ice glacier look beautiful. Very good composition and exposure handling. TFS
Selen

Hello James,
Amazing textures, and the difficult subject is very well captured!
Attractive diagonal composition with great details... A cool image!
Greetings,
Pablo -

selam james; amazing shot of this landscape ,good details presented ,nice BG and POV well captured with splendid colours TFS
regards
ridvan

Hi James.
Just like opening the freezer door, I can feel the chill from here. Excellent detail, what a huge wall of ice.
Ditto to Pablos comments on amazing texture detail and those diagonal lines.
Wonderful

Hi James,
Wow....what a coool shot. Mammoth formations these with very coarse surface. Very soothing colours and very impressive sharpness. I like your POV to capture the ambience and the chilly feeling. Very nicely composed. Kudos.
TFS.

Hi James,
even it's snow and ice it's a beautiful picture with natural colours. The spapes of the ice is amazing.
Good details and well exposed. And a very good note.
Great work.

Hello James,
An excellent view/composition with great detail.
Love the "old ice" blue color that comes through, very well exposed.
Thanx for the note..perhaps it's time to think about moving to higher ground? ;}
Howard

Hi James,
A lovely shot. I already felt chilled after seeing this. brrrrr. Nice colors. Thanks a lot for sharing.

Hi James,
Funny to post such a cool photo for our friend Ram. I am sure that by looking at it his temps will drop a few degrees.
A great photo where the exposure is really perfect, showing the real color of the ice. Sharpness and composition are wonderful. Did you also manage to get a shot of a piece of ice breaking off?
TFS,
Niek

Hi James,
This is a great study of light, shadow, and texture. Nice detail across the entire tonal range. Well composed. That is a massive hunk of ice.
Scott

James, I am humbled by your kind gesture.
And thanks for making me feel 'cool' by posting this glacier image from Argentina -- a place I would never be able to see with my own eyes in my remaining lifetime :-).

A superb image by virtue of amazingly beautiful contrasts between the blue and not-so-blue parts of the ice. Even as you took this shot, a piece of ice seems to have peeled off the mass and fallen into water.

You explain the phenomenon of blue ice very well in your note. On Khumbu Glacier in the Everest region in Nepal, I have observed pool like ice formations on the surface of the scree and rock covered glacier with deep blue sides. Used to wonder why they looked blue. Now I know.
Thanks and kind regards.

Hi Gary,
i visited the Bosson Glacier in the French Alps a few years ago, and the sound of creaking and breaking ice is quite awesome. This however is on a different scale!
That blue is just beautiful, and the jagged pinnacles are spectacular. Great exposure and excellent POV, a lovely sight that we should make the most of..

Paul.

..and then cameras tend to intensify the blues in ice ,thus such an amazing colored glacier in your photo. It is a great shot. I love the textured, bumpy surface.

Hello James

A wonderful shot of this glacier.The details are very good.I like the POV.The humidex was 42 C here today so this was a refreshing post.Nicely composed and well transferred from a slide.TFS

Hello James,
very impressive picture of this South American Glacier taken from an excellent point of view. The note also is great and instructive. I come from the Alpine area, where unfortunately gaciers are melting very fast at the moment.
Thank's and best regards

Hi James,
I think those days we all enjoy a little cooler environment ;-).
Great shot, the blue ice looks really refreshing. Very nicely composed, PV, sharpness and colors are wonderful.
Sky

Ana mazing sight James, but what's the scale, I can't get my head around it. I'm taking it this is ariel and those ice cliffs are 40'.

Blues are intense, the scan has worked well.

Gary

Hello James,
C'est une photo tellement précieuse; j'espère seulement qu'elle ne deviendra pas historique :) Bravo pour toute la technique et les notes, impressionnant! La nature est forte et je garde confiance en la race humaine, la vapeur se renverse :)
Claudine

Hello James,
I really like to watch your presenation because it is never known from wich part of the world the next photo will be :) You are "jumping" from desert places to really cold places like this one, or to tropical areas. And bravo for this gret "diversity"! :>
According to photo I have to say that as always it is very beautiful. I like a lot this blue composition. Very good DOF and details, also panoramic POV is nice for my eyes.
I just wonder how big were these ice cliffs, 20m? 40m? :)
TFS and have a nice day!
Radomir

Hi James,

what a really beautiful photo. There is so much detail and so much to see in this glacier. I love the top of the glacier receding into the BG...

TFS
Emma

Absolutely beautiful James! This is so refreshing to look at. The color of blue is so intense and your accompaning notes explains perfectly why. It's time to invest in a couple more inches upland, the way the climate is changing. :)

Hi James,
Beautiful blue in a terrific composition, tight and from an excellent pov. So, do you have any contingency plans to relocate when that one inch is exhausted? I hear Brits and Dutch are buying homes in Turkey for that reason. Regards,
Hakan

Hi James,
most pleasantly chilling! What a pleasure that look must be for Ram in Rhyad. I will save that image to put it on my desktop with rooms temperatures exceeding the 30s these days.
Fascinating density of structures, depth of colours, and a well decided foreground to maintain the enourmous natural size of the phenomenon.
With thanks, and best regards,
Peter
