Snow chimneys

Winter wonderlands can be home to
the unexpected sight of snow chimneys,

or fumaroles, puffing steam into the sky.
Occurring in volcanic regions, fumaroles are
openings in Earth’s surface from which hot

steam and volcanic gases are emitted.

Carbon dioxide, sulfur
dioxide, and hydrogen
sulfide are often emitted
from a fumarole, and a
gas mask should be worn
if confronting these
dangerous gases.

SNOW ROLLERS

Another unusual eye opener is the
snow roller. These giant cylinders develop
naturally, as smaller pieces of snow blown
by high winds gather more snow in a
traditional snowballing effect. They are
most commonly seen in cold regions
of North America and Europe.
