Frost (not Robert)

Frost on (some flower I don't know the name of)


Frost

This morning everything was covered in a thick layer of frost and when Paige got up and looked out the window, she thought that it snowed!

I ventured out with my Sigma 150mm macro lens and snapped a few pictures of a few blades of grass and some flowers just CRUSTED in frost.

    from Wikipedia:

    Radiation frost (also called hoar frost or, sometimes, hoarfrost) refers to the white ice crystals, loosely deposited on the ground or exposed objects, that form when the air is moist, the wind is weak or absent and surfaces are cold. It is often seen on clear winter nights, especially in valleys and hollows. Hoar frost can form in these areas even when the reported temperature is above the freezing point of water.

    One can distinguish between some types of hoar frost, 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 fernlike ice crystals directly deposited on snow, ice or already frozen surfaces; crevasse hoar consists in crystals that form in glacial crevasses where water vapour can accumulate under calm weather conditions; depth hoar refers to cup shaped, faceted crystals formed within dry snow, beneath the surface.
