Antarctica Weird Revisited

Remember this one from Jan 28, 2018? “More weird Stuff” post.

Photographed by NASA satellite in 1999.

The black rectangle measures 21 x 7km, and seems to have a reflective surface, or possibly has been ineptly whited out.
424km from Australia’s Davis Antarctic base.
And possibly has a track heading towards the south east?

Well, look at how it appears now in Google Earth.

Someone REALLY does NOT want us to see this area.
