The East Door of Strata Florida Abbey ("Vales of Flowers") indicates that the Abbey, in its heyday, was a substantial and significant church. It was a victim of the Dissolution. It is located near Tregaron, Wales.

The sun breaking through the rain clouds combined with a polarising filter really brought the colours out on the amazing rock strata at Sandymouth Beach.
Not quite an ex-palette. Oil on wood plus hatchet. Sadly rot had started to creep in after this had been ignored in a damp place, but it was improved substantially by being chopped up and rearranged.
Clouds hang against the strata exposed on the cliffs above the Going-To-The-Sun Highway in Glacier National Park, Montana. Theses sedimentary rocks were deposited in a shallow sea during the Proterozoic Eon between 1.6 to 1.8 billion years ago. The youngest of these rocks are the limestones and dolomites of the Shepard Formation which make up the massive beds at the top of the cliff. The next set of strata are partially hidden by the clouds and vegetation. If you look close at the right side, in the middle of the photo, you can make out the reddish to buff argillites (slightly metamorphosed shale), siltites (slightly metamorphosed siltstones) and quartzites (slightly metamorphosed sandstones) of the Snowslip Formation. These sediments were deposited on land in streams and mudflats adjacent to the ancient sea. The cliffs at the bottom of the photo are composed of thinly bedded limestones and dolomites with minor beds of argillite that composed the Helena or Siyeh Formation. These beds formed on the floor of the shallow sea. Some of the limestone beds are composed of beds formed of calcium carbonate precipitated by beds of cyanobacteria. The fossil cyanobacteria (called stromatolites) can be seen in the limestone. Glacier National Park has fascinating geology.
Side view on the Department of Geotechnology at TU Delft, Netherlands, an extension from 2008 to the existing Civil Engineering building. Architect was Jeanne Dekker.
The glass facade is imprinted with a pattern of stone slices (and not an x-ray image of some odd teeth as was my first thought :-)

Nature has endowed the relief of this vast rock formation with incredible colors. In Spanish, the Valle del Arcoiris means "Valley of the Rainbow", a name worthy of this grandiose landscape of red, white, yellow and brown cliffs standing out against the blue sky. This emblematic site of San Pedro de Atacama attracts visitors from all over the world to admire its splendid colors.
Geology at work, various strata exposed as a mountain has grown.
Okay, not really. Just a big pile of various dirts and gravels piled up and waiting for loading onto a ship at the Port of Redwood City, California. Told ya my mind was in a weird place today.
From pastel to bold, order to disorder, the sunset is reflected over the darkening foothills of the border ranges.

Colorful badlands strata in morning light, Death Valley National Park.
This subject may look familiar if you have been following my posts recently. It is a portrait-orientation composition of a feature that I also photographed in landscape orientation. (You might also think it looks a lot like a somewhat iconic feature in Death Valley — it does, a bit, but it is not the thing you may be thinking of.) This is a sort of photograph that I make frequently, a small “excerpt” of a much larger landscape scene, photographed with a long focal length lens. The just-arrived early morning light warmed the colors a bit and brought out the pink and blue tones of the layers.
These particular sorts of colors in the desert landscape have often challenged me as a photographer. They are geologically fascinating, but they are also often quite subtle, at least to my eye. In all but the best light they seem almost too faint to come through in a photograph. Some photographers compensate by significantly enhancing the intensity of the colors, but the result of that rarely satisfies me. Some particular qualities of the light made it work this time. Because it was shortly after dawn the light retained a warmer coloration. Some high, thin clouds muted and softened the light a bit. The band of darker material at the bottom contrasts with the lighter tones and with the colors.

I was standing sheltering from the rain, this is Scotland after all, looking out to sea and watching the boats in the distance. I was struck by the shapes of the rocks, the movement of the tidal flow and the winds pushing the clouds and that they all seemed to line up in horizontal bands. It made me think of the striations in a rock formation, hence the title.
This was captured in a single long exposure frame and processed twice from the raw file to produce a foreground and a background image. I hadn’t realised at the time that the larger boat was moving as much or I’d have captured another normal shot to clone it in. Unfortunately that little screen on the back of the camera isn't always enough to check everything.
The Strata Tower in Oklahoma City casts its reflection upon the façade of the adjacent 101 Park Avenue building. This interaction of modern architecture creates a visual dialogue between the two structures, showcasing the city's blend of historical and contemporary design elements.
Strata is a layer of sedimentary rock or soil with internally consistent characteristics that distinguish it from other layers.

The Portuguese island of Madeira is a paradise for geologists… Approximately 5 million years ago, the fiery birth of Madeira began deep beneath the Atlantic Ocean. As volcanic eruptions occurred, molten lava, ash, and rocks were expelled, gradually building up the islands' foundations.
A Sierra moment that I will forever remember, as if it were yesterday.
This spot is about 20 miles into the backcountry and a half day's trek from the nearest maintained trail. My initial plan was to drop down the other side of the pass for the night, but high altitude and a heavy pack slowed me down and sapped my energy, forcing me to plop down and set up camp on the summit of the pass. Then this happened.
As always, comments and real critiques are welcome, as are Sierra buffs who want to name some of the peaks in the background :)
If you really want the full experience here, make sure to view on black right next to its sister shot, Ride the Lightning!

Great Falls Park, Northern Virginia
"As long as I live, I'll hear waterfalls and birds and winds sing." - John Muir
Waterfalls are a joy of life. We are drawn to them for the fascinating sight of flowing water, the sounds generated by the physics involved, and sometimes to merely marvel that a substance so soft can, over time, cut through the hardest stone. I am drawn to them more than any other natural feature. How appropriate then for me to return to my favorite waterfall in Virginia, on my birthday, with my new camera and tripod in hand.
There is this wonderful window of time at Great Falls Overlook 1, short as 10 minutes, when the newborn sun rises above the Maryland bank of the Potomac River and illuminates the far Virginia side, before the rays reach the rocks, spoiling the balance of light. This is that moment.
Another shot of this view on a hazy day can be seen here.
