It's very clean, although some sink holes on Earth have clean circular edges too.

I'll apologise to the hollow Earth believers that I antagonised

[Simpo Two]

'The circles in the ice is thought to where the dry ice has sublimated into gas'

or even:

'The circles in the ice ARE thought to BE where the dry ice has SUBLIMED into gas'

If they can't write English their other credentials are immediately suspect.

An intersting picture - and one that fired my imagination. At first I thought 'does it show some sort of cavern below'?
But alas - having looked again I think its possibly an impact crater and the lighting is making it look more interesting than it is. Of course - for that theory to be true youd have to ignore the lack of debris around it - so who knows?
