LEFT: A column-type snowflake that later
grew plate-type crystals from either side
as temperatures dropped slightly.
BELOW LEFT: A "bullet rosette" type
of snowflake featuring multiple column
crystals originating from the same point.
Four crystals forming in symmetry is
quite unusual.
BELOW: An exotic snowflake based on
"arrowhead" crystal growth patterns.
Branches grow outward from the main
repeating body.
OPPOSITE TOP: Large blocky snowflakes
form in lower humidity, with broad
branches and a solid footprint. This one
has added layers of depth within.
OPPOSITE BOTTOM: With side-branches
that resemble razor blades, a snowflake
of this design forms in very stable
conditions. A brief pulse of increased
humidity causes the trident-like branches
to form.
