Weird anomalies

Guys, check out these weird things on Antarctica that are countless miles from anywhere. The first is a
giant hole into the earth, about 245 feet wide by 105 feet high.

Here it is in 3D showing that it is an opening into something, but what?

And if you think that is weird, check this out. About 4.8 miles to the south west is this....another opening, about 95 feet by 57 feet, with what is apparently a manufactured hatch over it that is open. WTF?

Here it is in 3D showing that it is a hatch over a very large opening.

What the heck can these be? There is no sign of any activity anywhere around them but they hardly look
natural, especially the one with the cover. If that isn't a manufactured cover....what the heck is it? A crashed UFO?

Weird stuff.
