“WHY? …here is the best answer I can give: Because. Because sometimes there aren’t really answers to our questions except for what we discover, and the meaning we assign them over time.”
― Libba Bray

Pancake Ice
This weather phenomenon is usually seen in places like the Baltic Sea around Antarctica and in the Great Lakes of Canada, but can occur wherever the right conditions exist, usually just below 0 degrees Fahrenheit. Freezing foam gets sucked into eddies that twirl the ice formation into circular pancakes.
