I have found a high resolution image of Antarctica which has a higher resolution than that in google earth
http://lima.usgs.gov/
If you zoom out to get the overall view of the Antarctica, you will see a big circle area plus some triangle area.
When you zoom in at the edge of this circle, you will see this
And the image at the highest resolution
IMO, someone intentionally reduced the resolution of the image. It should have been a better cover up if it is a missing strip of image. This doesn't prove that the earth is hollow, but it is a prove that something is going on at the south pole.
