One day, I was reading a newspaper, when I saw an article on scientist theorizing the presence of ice pyramids on Europa. The picture given with the article was small pyramids of ice on some mountain in South America, and they looked so much like Pol's terrain scatter that it got me thinking...
After some googling, I found this article on Wikipedia - apparently these ice formations are called Penitentes, and are found in cold but extremely dry areas - like Pol! The article also has references to the presence of such formations on Europa and Pluto, both icy worlds.
So, since Terrain Scatter has been there for a long time, I'm somewhat surprised to see no references to this fact. Kinda interesting, don't you think?

Penitentes in the Atacama Desert
So I conclude that Pol is actually an icy world - maybe a comet or something? idk
