South Pole Snow Puff Ball

Update: Mystery solved!

Today I noticed a large number of little snow puff balls outside. First I couldn’t figure out where they came from. After a while I did notice many of them just being blown across the ground like tumbleweed. It seems, that in calm conditions a light snow fuzz builds up on the surface. If this is followed by just the right amount of wind (currently around 10 knots) it just takes a small seed to start a puff ball, which will grow as it rolls across the Antarctic plateau.

The puff balls will gather in small depressions.

In the seven second video you can see the little puff ball tumbleweeding across the ground until it hits an obstruction and breaks up.

Update:
They just kept coming. I took a picture of a field of puff balls right in front of the Geographic South Pole later in the day.
