The block of wood and the iceberg it was attached to was found 66 degrees south and just a tad north of Commonwealth Bay. It was spotted by wildlife watchers near Aurora Australis’ bridge. It was first assumed as a seal resting on the iceberg, but then they realized that it was a rectangular piece.
What is also interesting is that the area is near the non-magnetic south pole. The geomagnetic field line are vertical rather than lying across the planet from pole to pole. This area creates a void where compasses don’t work.
No one seems to have a real theory about how this block landed on and continues to float around on this iceberg yet. It is definitely baffling.
