Space port opening discovered in Antarctica

I was messing around with Google earth checking out Antarctica. While looking around I came across an anomaly. Now Google earth is known for some anomalies because they like to hide things at the request of governments. They may be secret government related whatever. However, this doesn’t look like it’s been hit yet on the “coverup” list.

Zooming into the area in question

More details are coming into focus

Clearly when you look at the photos, it looks as if there is a large opening almost a port for a ship, a spaceship. And check out the edges. They seem to have an offset zig-zag pattern. A pattern that if brought closet together would creat a perfect fit and seal.
