In October 2018, NASA's IceBridge project captured this vision of a strange rectangular iceberg in Antarctica.

Earlier this month, NASA released a strange and compelling photo of a ridiculously square iceberg. And NASA scientist Kelly Brunt speculated on Live Science that the iceberg was likely to be cool, its sharp cracks were the result of a recent rupture of an ice shelf and not yet been hit by the elements.
Since then, however, NASA came back and looked at other tests. And it turns out that the squareberg had a rougher birth than initially believed. Satellite images showed that it split from the ice shelf of Larsen C which splintered in Antarctica behind a much larger and curved iceberg called A-68 and headed north in icy, clogged water.
The squareberg is a tabular iceberg, essentially a flat piece of ice that has broken from the ice shelf, rather than one of the most surprisingly geometrical and small icebergs that sank the Titanic.
"The iceberg has crossed all the way to the north and through a narrow passage between the northern tip of A-68 and a rocky outcrop near the ice shelf known as Bawden Ice Rise," NASA said in a note. "The NASA / UMBC glaciologist Chris Shuman compares this area to a nutcracker: A-68 has repeatedly crashed against the rise and caused shards of ice to splinters in clean geometric shapes," added NASA referring to Shuman, which is also at Baltimore County University in Maryland.
In this photo you can see the iceberg making its way through dangerous waters:
Over time, it has lost its beautiful square shape, taking on more than a trapezoidal formation. NASA said it will probably continue to the north, where it will melt.
