Snowflakes — wondrous wintry marvels — can take on a variety of unique shapes.

But icicles can also form a range of stunning patterns as well.

Melting ice can create long and impressive — sometimes terrifying — structures.

The size and shape of icicles vary depending on their surroundings. In the Arctic, entire icebergs can be altered by shifts in water temperature and currents.
