STILL THERE MASIVE. 5 MILES BY 15 MILES RECTANGLE. i have an image from Antarctica that appears to be 5 miles wide by 15 miles long. it is an anomaly in the area. When I get close up from Google earth there is visible snow that has been moved. I cannot get the proper resolution from Google earth to determine what ish this large and is a complete rectangle with perfect dimensions. I have a picture saved but can you tell me where to find a better image of the area? It looks whited out on purpose and is a different color then the surrounding snow. PLEASE SEE ATTACHED PHOTO FROM GOOGLE EARTH.?
