This strange phenomenon is caused by warm humid air passing
over sub-zero snow on the floor. Each single H20 molecule gently
locks into place like a little magnet, while the crystal slowly
grows and grows.
It is identicle to the process by which a snowflake forms, except
in this situation each "tree" is just one of the snowflake's
arms, and these crystal trees are many hundreds of times bigger
The shape and polarity of the water molecule contribute to the
shape of the crystal.
The water molecule is a little triangular magnet (positive top,

Ice crystals cover the ground like a blanket of miniature glass trees.
Snow wrinkles covered in crystaline fur.
Ice crystals growing in lockes of hairlike tufts.
More interesting ice crystalization.
All of the snow in the entire southern end of Utah was covered in
these sparklely ice crystals.
