This
site
describes
snow
crystals
and
snowflakes.
Although
a
common
meteorological
phenomenon,
snow
crystal
growth
is
a
fascinating
and
poorly
understood
process,
in
which
remarkably
complex
and
beautifully
symmetric
structures
appear,
quite
literally,
out
of
thin
air.
The
many
facets
of
snow
crystals
are
described
here,
along
with
the
attempts
to
understand
their
formation.
