The Escaldes-Engordany Bridge is a Romanesque bridge of medieval origin, located in the Andorran parish of Escaldes-Engordany. Cross over the river Valira de Oriente and connect the towns of Les Escaldes and Engordany.
Its structure is of a single arch, has a parapet and has as a singularity that it is quite asymmetric, due to the unevenness of the two extremes.
no idea where these are from, but I've been waiting to use them for something:)

One of the many narrow streets in the amazing old town of Goslar in Lower Saxony, Germany.
The city center contains many old buildings that date back hundrets of years because of which the district is protected as a UNESCO world heritage.

Last one hanging. Colonial park area, Harrisburg, Pennsylvania.
Thank you for looking!
1/500 sec. f/6.3 214mm ISO100
Then let my thought contemplative explore
This fleeting state of things, the vain delights,
The fruitless toils, that still our search elude,
As through the wilderness of life we rove.

Thank you very muh for the visits, faves and comments. Cheers
Black-fronted Dotterel
Scientific Name: Elseyornis melanops
Description: The Black-fronted Dotterel is a small wader with a distinctive black face-mask and breast-band and prominent chestnut scapulars (shoulder feathers). In juveniles, the breast-band is initially absent but a brown band slowly appears as the bird develops. Legs are pink orange, and the bill is red with a black tip. The dark eye is ringed with red. In flight the wings look broad and the tail short, while the black and white contrast is striking. Flight is slow with almost hesitant wing beats. This species is also called the Black-fronted Plover.
Similar species: The adult and immature Black-fronted Dotterel are unmistakable, though the juvenile could be confused with the juvenile and immature Red-capped Plover.
Distribution: The Black-fronted Dotterel is widespread throughout Australasia.
Habitat: The Black-fronted Dotterel is found in the shallow margins of wetlands, lakes, rivers, sewage farms, storm drains and marshes. It is normally always near freshwater and is not often seen on the coast.
Seasonal movements: Breeding resident.
Feeding: The Black-fronted Dotterel eats small molluscs as well as aquatic and terrestrial insects. When it forages, it keeps its body horizontal while bobbing its head to look for food, often running then stopping suddenly to peck at food items.
Breeding: The Black-fronted Dotterel lays its eggs in a shallow scrape, often on pebbly ground and quite close to water. It may have more then one brood per year. Both parents incubate the eggs and look after the young.
Calls: Sharp 'tip' call, singular or repeated three or four times.
Minimum Size: 16cm
Maximum Size: 18cm
Average size: 17cm
Average weight: 32g
Breeding season: September to February
Clutch Size: 2 to 3 eggs
Incubation: 27 days
Nestling Period: 25 days

San Salvador de Cantamuda que hasta el siglo XVI se denominaba San Salvador de Campo de Muga de Pernía. El pueblo surgió alrededor de la Colegiata de San Salvador, fundada por la Condesa de Castilla Doña María Elvira, mujer del conde Rodrigo Guntis y sobrina de Fernando I, que en ella fue enterrada.
Lo más fotogénico del aspecto exterior es su fachada occidental, con la que podría ser la más bella espadaña del románico español.
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.

Tina es una perra pequeña, apenas dos kilos y medio de peso, es oscura de pelo y ojos tristes y brillantes. Es de una de mis dos hijas y la adoptó de una perrera, estaba en la calle y tiene unos seis años. No se sabe si se perdió o sus antiguos dueños la abandonaron a su suerte. Ahora vive feliz, pero tiene siempre un toque de pesadumbre casi humana, te mueve el rabo con parsimonia casi como si quisiera decirte que aún no se cree su suerte, es muy querida por su nueva familia y estará entre ellos siempre. Una buena amiga y compañera...Tina
