Cool Grinding Surface images

A couple of nice grinding surface pictures I located:

Herald of spring.

When cozy winter
requires a step back.
And our sun
decides to get up,
each day a bit.
This does not remain unnoticed.

It is then
when Nature
get´s itself prepared
for a new round in the game.
Plants prepare
to sally and find their way
by way of the surface
to harvest light.

This all,
a large race it is.
Waiting at the start line.
No a single wants to commence too early,
it appears.

Birds start to sing their song,
to discover a partner and get along.
And then,
1st 1,
then a lot of.
You see snowflakes.
This time from the ground,
not from the sky,
breaking through.
Heralds of spring.
Proclaiming silently:
“May it commence.”

Solarized Hoar Frost Lane

My Samsung Galaxy S3 Phone has an fascinating setting generating this shot!

Hoar Frost (also known as radiation frost or hoarfrost or pruina) refers to the white ice crystals, loosely deposited on the ground or exposed objects, that form on cold clear nights when heat is lost into the open sky causing objects to turn out to be colder than the surrounding air. A connected effect is flood frost or frost pocket which happens when air cooled by ground-level radiation losses travels downhill to type pockets of extremely cold air in depressions, valleys, and hollows. Hoar Frost can type in these regions even when the air temperature a couple of feet above ground is nicely above freezing. Nonetheless the frost itself will be at or beneath the freezing temperature of water.
Hoar Frost may possibly have distinct names depending on where it forms. For example, air hoar is a deposit of hoar frost on objects above the surface, such as tree branches, plant stems, wires surface hoar is formed by fern-like ice crystals straight deposited on snow, ice or currently frozen surfaces crevasse hoar consists of crystals that kind in glacial crevasses exactly where water vapor can accumulate below calm weather conditions depth hoar refers to cup shaped, faceted crystals formed inside dry snow, beneath the surface.
