That is the continent of Antarctica and the ice on top of it. The fact that the circular area at the South Pole is clear is an anomaly. There isn't a heck of a lot to see there other than the ice pack.
I got another one ....im attaching the link...not sure how to atach screen pict.
but in case its not clear....what is that black line below the bottom half of Greenland...looks like a runway....and once you find it......zoom in as much as possible....are those runway LIGHTS on each side of the runway? interesting.
