Behind the metal frame and glass panels, stairs and an escalator lead up to an enclosed walkway (overpass) over Macleod Trail, one of Calgary's busiest roads, and on to Chinook Centre shopping mall.
Note how the curved design of the red benches contrasts with the straight lines and angles of the structure behind them.
Regarding architecture, it is often said that "form follows function." While true in many cases, this ignores the fact that architects can also use frivolous architectural forms to show off, to indulge their egotism and vanity, and to attract attention to themselves for the purpose of obtaining future commissions. Viewers should ask themselves, "What is the purpose, the function, of the diagonal linear forms and triangular shapes on the outside of the structure [in the photo above]?" Mere decoration? Artistry that enhances the urban environment?

I uploaded this view of East Turks Head to prove it wasn't always storming on my trip through the San Juan Mountains during the 2017 New Mexico Geological Society Fall Field Conference.
Of course, behind me, to the east, it was storming...
This is going to be one of those Geology intensive descriptions so be fore-warned.
East Turks Head Peak shows several interesting features that help explain the geologic history of Southwest Colorado.
Look at the cliff near the top of East Turks Head, See the reddish beds underneath the grey cliffs? One of the beds is relatively flat and the other dips slightly to the left (if you hover your cursor over the photograph, you should be able to see the labels I placed on the photograph).
The dipping beds are the Permian Cutler Group or Formation. If you have admired the Fisher Towers north of Moab, you were looking at the Cutler group. These sediments were eroded off of the Ancestral Rockies , in particular, the Uncompahgre Uplift portion of the Ancestral Rockies. This area was uplifted during the Pennsylvanian and Permian boundary about 300 to 275 million years ago.
The flat-lying sediments on top of the Cutler Group are the Telluride Conglomerate formation. The Telluride Conglomerate is only about 28 million years old. That means that at the contact between the Cutler and the Telluride (right below the dark red band at the base of the Telluride) there is a gap of about 250 million years of missing sediments. We call this an unconformity and because the beds are slightly dipping below the contact with respect to the overlying beds, we call this an angular unconformity.
That 250 years of missing section covers the entire age of the dinosaurs. From th earliest dinosaurs in the Triassic, through the age of Dinosaurs in the Jurassic, through their eventual extinction at the end of the Cretaceous. All gone.
So what happened? Were sediments never deposited here? Was this area mountainous throughout the missing interval?
Fortunately, by looking at the nearby areas and the nature of the deposits there, we can make a pretty good guess.
After the Ancestral Rockies were formed, this area began to be filled with sediments eroded of off them. In addition to the lowering of the land surface from erosion, this are also began to sink regionally possibly from cooling of deep magmas that helped push up the Ancestral Rockies. During the Jurassic, great coastal sand dune desserts formed to the southwest and deposited or layed down the beautiful Navajo Sandstone that is seen in so many of our National Parks and Monuments.
Later this area continued to sink and the seaway formed during the Cretaceous. This area was once covered by the famous Cretaceous sediments: The Mancos, Book Cliff, Cliff House, and Dakota Formations were deposited here.
So what happened to these sediments? Something big happened and something big usually involves a tectonic plate. It certainly does here.
A Pacific plate named the Farallon Plate did something unusual. Ocean plates like the Farallon plate usually get pushed down under a continental plate when they collide. They get pushed down at about a 30 degree angle and start melting as they get near the mantle. If the plate contains water, and oceanic plates usually do, some of the plate melts earlier and molten magma begins to rise through the overlying continental plate and may eventually reach the surface and erupt or cool in place in the upper continental crust rocks. These volcanoes are usually located back from the coast because the oceanic plate needs to travel down at that 30 degree angle for a while until it starts to melt. The Cascades and the Andes are good modern examples of this and are located 60 to 100 miles inland from the subduction zone where the oceanic plate begins to be carried downward.
The Farallon plate behaved that way for most of its history and the Sierra Mountains of Eastern California were formed by the Farallon plate subduction.
Near the end of the Cretaceous, however, that whole process changed. The Farallon plate instead of being pulled down into the mantle, suddenly broke apart and the new leading edge started moving east just underneath the bottom of the North American plate. It pushed eastward in two main pulses. The oldest created the Sevier Mountains and fault zone of western Utah. When the plate started to move eastward again, it created the Laramide thrust and Rocky mountains.
This lifted Southwest Colorado along with a broad swath of Central North America. The inland sea disappeared as this area was raised by the compression caused by the Farallon plate rippling underneath the North American plate.
The story doesn't end here however and you can see the results in East Turks Head. After the Laramide compression and thrust marked the eastward progression of the Farallon plate, the compression and eastward movement suddenly stopped. The Farallon plate started to slowly sink down into the mantle. As it sank, some parts started to sink and melt especially those parts that again, contained a lot of water. Eventually magmas formed and began to rise pushing up this area again. The Telluride Conglomerate is thought to be a result of the initial Laramide Rockies being eroded and the eroded parts of the doming San Juan area being pushed up by the now rising magma stocks.
The grey rocks at the top of the peak mark another phase
in the story. They are the San Juan Formation volcanics.
When I said that magma started to rise from the sinking or foundering Farallon plate I should have said a lot of magma started to rise. This resulted in huge eruptions. Just east of here, there was an explosion to rival the huge caldera at Yellowstone. In fact, the volcano with the highest Volcanic Explosivity Index or VEI is one of the nearby calderas in the San Juan Volcanic Field - La Garita. There were more calderas in this area, each one blasting many hundreds to thousands of square miles of material up into the sky and back down onto the earth creating the San Juan formation.
The San Juan formation looks thick on top of East Turks Head but imagine 2.5 kilometers more material piled on top of the peak and imagine how big the explosions must have been to deposit that much material.
The magma caused another phenomena in southwest Colorado. The deep waters that came in contact with these huge stocks of magma were heated and infused with heavy metals from the magma including gold and silver. The hot metal laden water rises up through the overlying rocks thermally altering the rock and depositing the metals as it cools near the surface. Red Mountain a little further north of East Turks Head along US 550 is an example of an entire mountain that has been hydrothermally altered by these hot deep waters. If you ever see it, you will immediately understand what the results of thermal alteration are.
Finally, this area that includes the San Juan Mountains is the highest average elevation in the continental United States.
One of the presentations at the conference presented the results of a seismic study of the southwest corner of Colorado. The results of the study suggest that something special is occurring under this high area. High areas in continents are usually supported by deep roots. In essence, high mountains float on deep roots below them.
That doesn't seem to be the case here. The study suggests that the crust is thin here. It is also hotter than normal and this heat is what is expanding the rocks and lifting them up. The lift is a little slower than we can measure just now but the ragged appearance of these mountains indicates that it is a very young landscape still slowly rising and with erosive forces still actively trying to plane these peaks down.
I hope this description helps you to think about the interesting story of how this natural beauty evolved. Take another look, I think you will find it worth while.

I have written a tutorial on long exposure photography and post processing here.
Created using the Fractal Science Kit fractal generator. See www.fractalsciencekit.com/ for details.
At the Orange Campus in Balma, I focused on the stark geometric patterns created by the modern architecture. The black and white treatment emphasizes the dynamic interplay of lines, creating an abstract study of light and shadow.
Umspannwerk Favoriten (Substation Favorite), Vienna, Austria.
Architects: Eugen Kastner, Fritz Waage
Built: 1929-1931
The functional building represents "the international influence of the constructive coupling of self-sufficient volumes" and was possibly influenced by Soviet revolutionary architecture. The building, which was built on a triangular plot of land that was rather unfavorable for the purpose, is characterized by a purely technical need, namely the accommodating large transformers, an obligatory design that lines rounded up or interlocks and angular structures, which gives the building a futuristic and technocratic character. Supported by the three-sided floor plan, the association of a large ship's hull is also obvious: Eugen Kastner and Fritz Waage have, for example, designed the chief office as a command bridge projecting beyond the building, as is common on ships. Circular windows are reminiscent of the portholes of an ocean liner.
Today, the Favoriten substation is one of the oldest substations of Wiener Netze GmbH, which is still in operation after the technical equipment was renewed. Because of its special shape, the building has repeatedly been used as a film backdrop.

The Casa de les Punxes or Casa Terradas is a building designed by the modernist architect Josep Puig i Cadafalch. Located in the intersection between the streets of Rosselló, Bruc and the Avinguda Diagonal in the Barcelona Eixample area.
Designed by modernist architect Josep Puig i Cadafalch, la Casa de les Punxes is located in the intersection of the three surrounding streets Avinguda Diagonal, Carrer Rosselló and Carrer Bruc, in the Eixample of Barcelona.
In 1905, Bartomeu Terradas Brutau commissioned Josep Puig i Cadafalch to design a house for each of his three sisters, Angela, Josefa and Rosa. The result was a building reminiscent of old medieval castles, with elements of different architectural trends and various technical innovations, with six pointed towers (crowned by conical spikes), one of its distinctive features which gave the popular name of Casa de les Punxes.
This spectacular building is one of the most emblematic of Barcelona, as well as being key to understanding the movement of Catalan Modernism. Declared a historical monument of National Interest in 1976, Casa de les Punxes is one of the most emblematic buildings in Barcelona. It is now privately owned, with space for different offices.
La Casa de les Punxes, also known as Casa Terradas, underwent rehabilitation work in 2016 inside one of the buildings. These renovations were executed under the guidance of architect Jaume Falguera.
It has always been a tourist attraction thanks to its façade and its location among other tourist spots of the city such as La Pedrera or La Sagrada Familia.
CATALÀ
La casa de les Punxes o casa Terradas és un edifici de Barcelona dissenyat per l'arquitecte modernista Josep Puig i Cadafalch, gran coneixedor del gòtic europeu, tornà a usar el llenguatge medievalitzant, revisat amb motius populars, que fa que superi el caràcter purament historicista que altrament podria tenir l’edifici. L'edifici es troba entre els carrers de Rosselló, Bruc i l'avinguda Diagonal a l'Eixample de Barcelona. Va ser declarat Bé Cultural d'Interès Nacional el 9 de gener del 1976.
La casa Terrades, anomenada popularment la casa de les "Punxes", per la seva estructura visible, forma una illa de cases irregular, entre l'avinguda de la Diagonal i els carrers del Rosselló, de Llúria i del Bruc.
Es tracta de tres edificis que formen un volum unitari, amb celoberts trapezials, ordenadors de l'interior. Exteriorment, és format per sis façanes articulades als angles per sis torres cilíndriques acabades en cuculles, el més gran amb una llanterna.
Tret de la planta baixa, on pràcticament s'usà només la pedra, la resta de l'edifici és de maó vist, amb detalls escultòrics de pedra -tribunes, emmarcaments de balcons, pinacles, sanefes decoratives-, cuculles de ceràmica vidriada i teulada de teula àrab. Hi destaquen també alguns treballs de forja i plafons de ceràmica de colors a la part superior d'alguns sectors de les façanes.
Les obertures de la planta baixa, un seguit d'arcs de mig punt, formen una galeria seguida, interrumpuda en escasses ocasions per uns petits cossos -de maó vist-, sobre els quals sobresurten tres nivells superposats de tribunes.
La importància de la planta noble es fa palesa especialment a la façana de la Diagonal, on apareixen balcons -amb barana i altres de forja-, les obertures de les quals reprodueixen models propis, no ja del gòtic sinó del renaixement. La resta d'obertures combinen la llinda, els arcs rebaixats i els arcs de mig punt. L'acabament de la torre principal és resolt amb barbacanes.
El coronament de les façanes, amb les teulades a dues vessants, no es tradueix, però, a l'interior, cobert per un terrat pla. Les torres angulars amb sengles cuculles contribueixen a donar-li l'aspecte de castell nòrdic.
A la casa Terrades, Puig i Cadafalch, gran coneixedor del gòtic europeu, torna a usar un llenguatge medievalitzant juntament amb motius populars que fan que superi el caràcter purament historicista que altrament podria tenir l’edifici.
Not my best shot, but a must after my last post, where I wrote that star trails are caused by earth rotation (angular motion).
Of course any rotation of the camera will lead to circular star trails. You can therefore also rotate your mount to achieve the effect. That's what happened here when I initiated a turn with my flying mount.
You can see the turning path in the cloud cover below, while the roll caused the star trails.

A veces cuando estoy ante estas “estampas” visuales me da por pensar que parecen una imagen irreal, una foto donde se puede observar una belleza que no ha sido creada ni diseñada por nadie, un momento único que solo se plasma de la manera más maravillosa en nuestras retinas y que ninguna cámara puede captar. Hemos puesto tanto empeño en modificar, mejorar, diseñar nuestra vida y lo que la rodea que a veces estas visiones naturales hasta nos parecen artificiales. Rayos de sol filtrándose entre nubes con formas caprichosas que amenazan lluvia por encima de nuestras cabezas, olas que se deleitan deslizándose por las rocas un millón de veces, el viento cambiante que vuela por encima del océano hasta llegar al horizonte y volver…etc. Impertérrita una escalera colocada por el hombre permanece inmóvil en medio del espectáculo, cuya única finalidad parecer recordarnos que ni siquiera allí la naturaleza ha podido zafarse del “progreso humano”.

In Madrid for 24 hours on business, but I managed to slip away just long enough to take some shots of the leaning towers of the Puerta de Europa. The two towers lean toward each other at a 15º angle; this is the Caja Madrid building and the sunset behind it, reflected in the windows of the Realia building.
