There is an aerial photograph here:

http://www.ibtimes.co.uk/two-km-wide-crater-antarctica-linked-2004-meteorite-impact-1482869

Not the best image to get an idea of the structure, but what makes me somewhat 
cautious is that it seems to be polygonal rather than circular. With polygonal 
structures, I am thinking: frost action (on a giant scale). It is Antarctica 
after all.

The same link above mentions that it might be visible on satellite images from 
25 yrs ago. If true, it is not connected to the inferred 2004 event.
