Icebreakers

From giant icebergs to delicate frost
formations, ice takes on some strange
structures in the world’s coolest places.

Frost beard
Frost beard resembles silky
white hair growing on wood,
like this log in Switzerland.
Logs absorb rain, but when the
water freezes in cold weather,
it expands out onto the wooden
exterior, exposing icy “hairs.”

Ice stripes
Icebergs are usually white,
but this one in Greenland
seems to have blue veins!
It is an example of striped
ice, which occurs when algae,
minerals, or sediment in seawater
freeze onto the underside of
an iceberg, creating streaks of
blue, yellow, brown, or black.
