Crystal Ice & Snow Flake

Crystal Ice


Snow Flake





Late November

This is the direct view from the back of our new home, taken in late November.


What I saw on the lake took my breath away -
the glittering ice crystals was struck by the sun's rays
and the colour from the winter sky cast the image with cold-blue ambient.










Early December

I visited the lake in early December and found the lake looked different.


It's now covered with many tiny s
nowflakes over the frozen surface.


I've learned later on that snowflakes has different shapes and names.
The one I found on the lake is called "Needle" snowflakes.




Needles Snow Flake
Needles snow flake are slender, columnar ice crystals that grow when the temperature is around -5 C (23 F). On your sleeve these snowflakes look like small bits of white hair.
One of the amazing things about snow crystals is that their growth changes from thin, flat plates to long, slender needles when the temperature changes by just a few degrees. Why this happens remains something of a scientific mystery.



A snowflake is a more general term; it can mean an individual snow crystal, or a few snow crystals stuck together, or large agglomerations of snow crystals that form "puff-balls" that float down from the clouds.


The story of a snowflake begins with water vapor in the air. Evaporation from oceans, lakes, and rivers puts water vapor into the air, as does transpiration from plants. Even you, every time you exhale, put water vapor into the air.


When you take a parcel of air and cool it down, at some point the water vapor it holds will begin to condense out.

When this happens near the ground level, the water may condense as dew on the grass. High above the ground, water vapor condenses onto dust particles in the air.


It condenses into countless minute droplets, where each droplet contains at least one dust particle. A cloud is nothing more than a huge collection of these water droplets suspended in the air.


As clear as it's seen, the water was totally frozen that I could walk on it.
