Take a look at these photos http://gr8pic.blogspot.com/2007/02/frozen-wave-antarctica.html

Is that really a frozen wave? If so, how has it happened?

For the sake of the above new member I have added this picture form the amazing set that the Docs link...links to !







I can not believe it's a wave !....I am guessing here but I suspect it must be something to do with the edge melting , water flowing then re-freezing many times !!!...oh.....I don't know.....could this happen in the antarctic ?...

......how about wind erosion ?

Whatever caused it, it's stunningly beautiful.

It is due to compression. The ice was formed as a flat sheet then bowed upward by compressive movement of the ice on either side of it. You can see the healed fractures and shear planes in the ice. These are the opaque layers that are seen in the ice in cross section.

Sorry about the science interfering with the beauty of this. It is stunning.

Snow also can have some cohesion.  Sheets of snow can creep and actually bend once consolidated.  Melt/freeze and wind are the forces at work.
