There appeers to be a perfectly formed rectangular shape iceberg doing the rounds in the South Pole.

cheers

Like the black one in 2001: A Space Odyssey?

It was either the CIA or contrails.

I'm not sure we can blame this on Brexit.

About 6 years ago heading up the High Arctic to Alert by helicopter,my engineer and I saw exactly the same thing between Grise Fjord and Eureka.

Don't tell the Chinese; they'll build an airfield on it and claim it as sovereign territory.:rolleyes:

Look, you're aware of the concept of an "ice cube", right? - this is just a slightly larger crystal.

It's just the cold climate version of that level playing field, that management often talk about.

Part of the giant ice wall that keeps the oceans in, as per Flat Earth Theory. Forrest Trump wants to drag it up to the border with Mexico to save money on concrete.

Relax, it's just part of the film set for Game of Thrones.... if you look hard you might see john Snow (no, NOT Jon Snow) ..... coat, hat.....

No it is the Saudis collecting fresh water to water the desert.

Apparently not all that uncommon:

So why is it so rectangular? Rectangular icebergs aren’t even all that unusual, although this one is a bit more rectangular than most. A typical large iceberg that breaks off an ice shelf, called a ‘tabular’ iceberg, will have a flat top and steep sides like the one spotted by IceBridge. In fact, most icebergs look something like this initially; it’s only after the iceberg melts and breaks apart that they become the irregular-shaped icebergs we’re more familiar with.

Just one end of it? We want to see the rest!

Why is the surface so much different to the surrounding ice?
Seems altogether too much like a billiard table.

The video footage that is available is from a perspective that can not be from a satellite. Way too low.

The video footage that is available is from a perspective that can not be from a satellite. Way too low.
It was during one of these regular surveillance flights that senior support scientist Jeremy Harbeck spotted an unusually angular iceberg floating just off the Larsen C ice shelf.
"I often see icebergs with relatively straight edges, but I've not really seen one before with two corners at such right angles like this one had," Harbeck said in a statement. (https://www.nasa.gov/image-feature/goddard/2018/2-rectangular-icebergs-spotted-on-nasa-icebridge-flight/)

Indeed. There's three other similar 'bergs within sight of the one pictured in the OP.

Because the iceberg was part of an ice sheet, that was built out by glaciers. It is covered in snow. The surrounding ice is "sea ice", which was formed from sea-water and is relatively thin and is prone to breaking up.

Quote from G-CPTN's link: "due to the structure of the snow crystals".

So, just a larger Jack Frost pattern, or a giant snow flake, both of which are stunningly beautiful, individual creations of Nature.

Unexplained = we, mankind don't really know what the hell is going on.<br /><br />Get your heads out of the snow or sand and just think for one moment. Is it natural? No it is not. Oh, so it must be man made. Yeah right.<br /><br />Please don't be so f****n naive to believe anything any government anywhere, tells you. You can take that to the bank.
