From Cross Fissures View with a view looking to the southeast across the canyon and gorge in Black Canyon of the Gunnison National Park. This was a differently positioned overlook at that point and allowed me to more center the fissures in the image. I felt angling my Nikon SLR camera slightly downward would create more of that sweeping view across the canyon and national park. The blue skies, I felt, were more of a negative space but still complemented the grandeur-type setting.
We are standing on the 3-foot thick (at least) fissured ice lens that sits atop Sky Pond during the winter months in Rocky Mountain National Park. To get here is a 4 mile hike in the snow up 1700 ft., climbing up hand over foot next to the frozen skeleton of Timberline Falls, to arrive at Sky Pond sitting just under 11000 ft. When we arrived, the peak wind gusts were howling at a good 40-50 mph, blowing snow was racing across the frozen surface of the lake, and the temperature was about 20 ˚F. When particularly strong gusts would roll over the Divide, the traction cables on my boots would nearly break free from their purchase in the ice. As we waited for morning light to hit The Sharkstooth, all I could do was stare into the depths: the myriad sizes, shapes, colors, and shadows in the ice were fascinating.
The great frozen and fissured sheet of the Vatnajökul rises behind its iceberg progeny, which themselves are pushed inexorably through the Jökulsárlón lagoon, and onward toward the nearby North Atlantic. Here, the only living things that offer any scale are the gulls, fulmars and terns.
To gain the freedom of the sea, and their concomitant salty demise, the ice must crash and tumble through a narrow outlet channel. The sudden and violent gyrations of the ice make swimming in that particular spot only for the seals, who seem to negotiate the passage with blubber-insulated ease. Gatherings of Arctic Terns also rest on the ice as it moves, and are flung suddenly into flight en masse when the ice is forced to a lower center of gravity by the channel bottom and the current. Once out to sea, smaller fragments of glacier ice are pushed by the tide, wave action, current, and the wind back onto the black sands of Diamond Beach. Once marooned, they slowly melt into the black grains, as their elegant faceted surfaces glimmer in the fogs and glint in the light.
Silfra is a fissure between the North American and Eurasian tectonic plates in Thingvellir National Park - Iceland. Clear water to the bottom(approx. 60 feet deep).

The Spa Pool as taken from another angle. It is a really interesting place to shoot and probably takes a bit of time to 'warm up' as the actual scene itself (non photographically) might not be as spectacular as you may think.
The Giant's Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic fissure eruption. It is located in County Antrim on the north coast of Northern Ireland, about three miles (4.8 km) northeast of the town of Bushmills.
Around 50 to 60 million years ago, during the Paleocene Epoch, Antrim was subject to intense volcanic activity, when highly fluid molten basalt intruded through chalk beds to form an extensive lava plateau. As the lava cooled, contraction occurred.
Horizontal contraction fractured in a similar way to drying mud, with the cracks propagating down as the mass cooled, leaving pillarlike structures, which are also fractured horizontally into "biscuits". In many cases the horizontal fracture has resulted in a bottom face that is convex while the upper face of the lower segment is concave, producing what are called "ball and socket" joints. The size of the columns is primarily determined by the speed at which lava from a volcanic eruption cools.
The extensive fracture network produced the distinctive columns seen today. The basalts were originally part of a great volcanic plateau called the Thulean Plateau which formed during the Paleocene.
According to legend, the columns are the remains of a causeway built by a giant. The story goes that the Irish giant Fionn mac Cumhaill (Finn MacCool), from the Fenian Cycle of Gaelic mythology, was challenged to a fight by the Scottish giant Benandonner. Fionn accepted the challenge and built the causeway across the North Channel so that the two giants could meet. In one version of the story, Fionn defeats Benandonner. In another, Fionn hides from Benandonner when he realises that his foe is much bigger than he is. Fionn's wife, Oonagh, disguises Fionn as a baby and tucks him in a cradle. When Benandonner sees the size of the 'baby', he reckons that its father, Fionn, must be a giant among giants. He flees back to Scotland in fright, destroying the causeway behind him so that Fionn would be unable to chase him down.
Across the sea, there are identical basalt columns (a part of the same ancient lava flow) at Fingal's Cave on the Scottish isle of Staffa, and it is possible that the story was influenced by this.
In overall Irish mythology, Fionn mac Cumhaill is not a giant but a hero with supernatural abilities, contrary to what this particular legend may suggest. In Fairy and Folk Tales of the Irish Peasantry (1888) it is noted that, over time, "the pagan gods of Ireland [...] grew smaller and smaller in the popular imagination, until they turned into the fairies; the pagan heroes grew bigger and bigger, until they turned into the giants". There are no surviving pre-Christian stories about the Giant's Causeway, but it may have originally been associated with the Fomorians (Fomhóraigh); the Irish name Clochán na bhFomhóraigh or Clochán na bhFomhórach means "stepping stones of the Fomhóraigh". The Fomhóraigh are a race of supernatural beings in Irish mythology who were sometimes described as giants and who may have originally been part of a pre-Christian pantheon
A quick but sweet visit to a vast, unique fissured basin in the death valley NP. I find it very fascinating how randomly these cracks form to create all kinds of interesting patterns.

Many requests have been received for example photos of asbestos ceiling tile and ceiling panels. Shown above is one example of an asbestos-containing suspended ceiling panel, one of many types, which are found in a seemingly countless array of surface patterns and textures. More examples of asbestos ceiling tile and panels will be offered for visual reference in some upcoming photos.
Ceiling tiles and panels are utilized to serve a variety of useful purposes, such as providing a level of fire-rated protection, absorb sound, conceal unsightly utility systems or cover over older building finishes, create air plenum spaces for HVAC operation, reduce total usable air volumes in occupied areas for HVAC efficiency, maintain a level of insulation value between building zones, and provide a simple decorative appearance.
This small section of non-descript ceiling panel with fractured edges is roughly about a quarter of a 2-ft. x 4-ft. panel that was formerly installed in a suspended ceiling grid or drop-ceiling system. A 1-inch cube has been placed for visual scale.
The panel section shows moisture staining on an otherwise smooth, white surface and also demonstrates a fairly common style of patterned perforations across its entire surface. The tiny pinholes and fissures provide an acoustic absorption value, one of the main purposes of practically all ceiling tiles and panels. Closer study of the panel's surface pattern reveals that there are two sizes of pinholes and that the fissures or crevices are oriented in a latitudinal direction.
Distinctions in a ceiling tile's appearance, however subtle, is an important factor when visually evaluating many tile materials with very similar visible charcteristics. Oftentimes, in the event that ceiling tiles and panels require replacement, building maintenance personnel attempt to match existing patterns as close as possible, which can be problematic to discern differences during an asbestos survey inspection.
Although not particularly evident about this rather ordinary-looking ceiling panel, especially from this view as most would see it suspended above their heads, it has been laboratory-tested and identified to contain approximately 5%-10% amosite asbestos.
To compound matters concerning ceiling tile and panels, as most who've dealt with this crumbly and messy material probably already know, the typical ceiling tile is indeed quite friable in its composition and is practically always considered a suspect material during an asbestos survey. The crumbly ceiling tile material can be very troublesome when contending with asbestos issues.
In the U.S., ceiling tile and ceiling panels are generally categorized by regulatory agencies as a "miscellaneous" material. When trying to deal with the removal of suspect ceiling tile/panels of unknown asbestos content, an accepted practice and conservative recommendation is to "assume" and treat the friable suspect ceiling tile material as asbestos until conclusive testing confirms either the presence or absence of asbestos via specialized laboratory microscopy methods (such as PLM), then treat accordingly.
Bulk samples of suspect asbestos materials should be collected by an experienced, trained, qualified, certified, and accredited inspector/surveyor for proper testing; proper removal and disposal of asbestos materials should be performed by trained, certified, and accredited/licensed asbestos abatement personnel.

Volcanic action left piles of boulders strewn across the Aruban landscape (similar action created the much larger rock formations in Joshua Tree National Park in California, USA). The Casibari Rocks is the largest set of formations on this Caribbean island known mostly for its beach resorts. Spread over a few acres of cactus gardens, Casibari is a peaceful spot for wonder and quiet contemplation.
Black Point Rock. Finally crested the last rise and could see the top. We hoped that from there we would be able to get a good vantage point and see where the fissures were.
