Au petit matin, les cristaux de glace de la gelée blanche qui s'est formée par sublimation de la vapeur d'eau contenue dans l'air froid, fondent progressivement aux premiers rayons du soleil.
EN: Well, i think i'm back? I lost my hand to make picture but, not too bad!
FR: Eh bien, je crois que je suis de retour? J'ai perdu la main pour faire des photos mais, c'est pas mal!
Another from the day out on Helvellyn, taken as the sun dropped below the ridge line of the Central Fells and shone through the mist in the valley and trees of the Swirls plantation. Cropped from the original in an attempt to simplify and distil the image.

simple sublimated circle
golden, molten ring,
spread across black satin,
across the limitless dome of the night.
the moon sang,
the stars twinkled,
the darkness embraced them,
lingering, still.

"...La sublimation n'est pas toujours la négation d'un désir ; elle ne se présente pas toujours comme une sublimation contre des instincts. Elle peut être une sublimation pour un idéal."
Gaston Bachelard
Sastrugi
Sastrugi, or zastrugi, are features formed by erosion of snow by wind. They are found in polar regions, and in snowy, wind-swept areas of temperate regions, such as frozen lakes or mountain ridges. Sastrugi are distinguished by upwind-facing points, resembling anvils, which move downwind as the surface erodes. These points usually lie along ridges parallel to the prevailing wind; they are steep on the windward side and sloping to the leeward side. Smaller irregularities of this type are known as ripples (small, ~10 mm high) or wind ridges.
Large sastrugi are troublesome to skiers and snowboarders. Traveling on the irregular surface of sastrugi can be very tiring, and can risk breaking equipment—ripples and waves are often undercut and the surface is hard and unforgiving, with constant minor topographic changes between ridge and trough.
Etymology
The words sastrugi and zastrugi are Russian-language plurals; the singular is zastruga. The form sastruga started as the German-language transliteration of the Russian word заструга (plural: заструги).
A Latin-type analogical singular sastrugus is used in various writings on exploration of the South Pole, including Robert Falcon Scott's expedition's diaries and Ernest Shackleton's The Heart of the Antarctic.
Formation mechanism
White and black colors on sastrugi are not lights and shadows, they demonstrate difference in radioreflectivity of snow deposits on the windward and leeward sides of a sastruga.
Under the action of steady wind, free snow particles accumulate and drift like the sand grains in barchan dunes, and the resulting drifting snow shapes are also popularly referred to as barchans. Inuit of Canada call them kalutoqaniq. When winds slacken, the drifted formations consolidate via sublimation and recrystallization. Subsequent winds erode kalutoqaniq into the sculptured forms of sastrugi. Inuit call large sculpturings kaioqlaq and small ripples tumarinyiq. Further erosion may turn kaioqlaq back into drifting kalutoqaniq. An intermediate stage of erosion is mapsuk, an overhanging shape. On the windward side of a ridge, the base erodes faster than the top, producing a shape like an anvil tip pointing upwind.
On sea ice
Sastrugi are more likely to form on first-year sea ice than on multiyear ice. First-year ice is smoother than multiyear ice, which allows the wind to pass uniformly over the surface without topographic obstructions. Except during the melt season, snow is dry and light in climates cold enough for sea ice, allowing the snow to be easily blown and create sastrugi parallel to the wind direction. The locations of sastrugi are fixed by March in the northern hemisphere and may be linked to the formation of melt ponds. Melt ponds are more likely to form in the depressions between sastrugi on first-year ice.

Hair ice, also called ice wool or frost beard, is a rare natural phenomenon in which a hair-like, woolly ice structure develops on dead and wet heartwood, not on the bark, of deciduous trees.
Hair ice can form when the air temperature is slightly below freezing. Fungi occur in the wood and the metabolism of these fungi, among other things, releases water that is forced out through very small openings in the wood. The water squeezed out freezes into a hair-like structure. High humidity is necessary for the successful formation of hair ice so that the water squeezed out cannot evaporate and remains available for freezing. As long as the fungi continue to produce water and the climatic conditions remain favorable, hair ice can continue to grow. If the air temperature becomes too low, the metabolism of the fungi drops to such a low level that insufficient water is produced.
Hair ice is very delicate and melts immediately upon contact. If hair ice is exposed to sunlight, it will quickly sublimate and disappear. Hair ice can therefore be found early in the morning or only in shady places.

IJshaar, ook wel haarijs of sneeuwbaard, is een zeldzaam natuurlijk verschijnsel waarbij een haarachtige, wollige ijsstructuur ontstaat op dood en nat kernhout, dus niet op de bast, van loofbomen.
IJshaar kan ontstaan als de luchttemperatuur even onder het vriespunt ligt. In het hout komen schimmels voor en bij de stofwisseling van deze schimmels komt onder andere water vrij dat door zeer kleine openingen in het hout (houtstralen) naar buiten wordt geperst. Het naar buiten geperste water bevriest tot een haarachtige structuur. Een hoge luchtvochtigheid is noodzakelijk voor de succesvolle vorming van ijshaar zodat het naar buiten geperste water niet kan verdampen en voor bevriezing beschikbaar blijft. Zolang de schimmels water blijven produceren en de klimatologische omstandigheden gunstig blijven, kan ijshaar aan blijven groeien. Als de luchttemperatuur te laag wordt, daalt de stofwisseling van de schimmels tot zo'n laag niveau dat er onvoldoende water geproduceerd wordt.
IJshaar is zeer teer en smelt na aanraking direct weg. Als ijshaar aan zonlicht wordt blootgesteld, zal het snel sublimeren en verdwijnen. IJshaar is daarom 's morgens vroeg of alleen op schaduwrijke plaatsen te vinden.

La gare des Guillemins change de visage et se pare de couleurs chatoyantes. C’est le projet porté par le groupe belge Uhoda, en collaboration avec la SNCB, la ville de Liège, la Province de Liège et la Fédération Wallonie-Bruxelles.
Si la gare des Guillemins est l’œuvre (d’art, dirons certains mais pour moi oui!) de l’architecte et plasticien espagnol Santiago Calatrava, c’est un autre artiste, français celui-ci, qui a la lourde tâche de sublimer le bâtiment: Daniel Buren. Il est à la fois peintre, sculpteur et plasticien, et est connu pour ses œuvres très colorées. L’une de ses plus récentes et remarquables créations est “L’Observatoire de la lumière”. En 2016, l’artiste français a recouvert les panneaux en verre qui composent le bâtiment de la Fondation Louis Vuitton de filtres colorés. Et c’est le même projet qu’il réalise à la gare des Guillemins. Cette œuvre éphémère sera visible durant un an.
le budget total s’élève toutefois à plus de 350.000 euros!
The Guillemins station changes its face and is adorned with shimmering colors. This is the project led by the Belgian group Uhoda, in collaboration with the SNCB, the city of Liège, the Province of Liège and the Wallonia-Brussels Federation.
If the Guillemins station is the work (of art, some would say but for me yes!) of the Spanish architect and visual artist Santiago Calatrava, it is another artist, French this one, who has the heavy task of sublimate the building: Daniel Buren. He is a painter, sculptor and visual artist, and is known for his very colorful works. One of his most recent and remarkable creations is “The Observatory of Light”. In 2016, the French artist covered the glass panels that make up the Fondation Louis Vuitton building with colored filters. And it is the same project that he is carrying out at the Guillemins station. An ephemeral work will be visible for a year.
however, the total budget amounts to more than 350,000 euros!

Thank you for any and all views, faves, invites to groups, comments and constructive critique. I’m not keen on: invitations to post 1 award 3; copy and paste comments (you know who you are); or links to your work. If you like my images there is a good chance I will like yours and I tend to reciprocate views as a matter of courtesy and personal interest.
