NASA Spots Strange Rectangular Iceberg in Antarctica
This is called a 'tabular' iceberg, and it's actually surprisingly common.

Floating off the coast of Antarctica is an iceberg, but not any normal iceberg you’ve ever seen. This particular iceberg is completely flat at the top, with square sides and right angles. It looks like a giant sheet cake floating in the ocean. While your first instinct might be to assume this particular chunk of ice is human-made, in reality it’s completely natural.
The cake-shaped iceberg was photographed on October 16 by NASA’s IceBridge program, which routinely flies planes over the poles to take photos and study how these remote locations are changing. In the past, these flights have mapped Greenland’s ice sheets, identified collapsing ice shelves, and spotted mysterious holes in the Antarctic ice.
