Scene at around 1500 m above sea level in the Alaska Range of Central Alaska. Patterned ground is the distinct, natural pattern of geometrical shapes formed by the deformation of ground material in remote regions of the Arctic and Antarctica. It has also been observed on Mars. The mechanism of the formation of patterned ground had long puzzled scientists but the introduction of computer-generated geological models in the past 20 years has allowed us to relate it to frost heaving, the expansion that occurs when wet, fine-grained and porous soils freeze. -- Adapted from Wikipedia.

This brute was growing at my cabin site in Carroll County, Ohio. The texture underneath the cap is porous. The top of the cap was very smooth.
.........words I don't want to use too much
Cause
They might wear out.
I saved some words mostly becuase
There are days
When I can't stay kissed.
Days when all my confidence
Wears off,
When I'm porous
And just have to have
More of you
To fill me in.

Hraunfossar (Borgarfjörður, western Iceland) is a series of waterfalls formed by rivulets streaming over a distance of about 900 meters out of the Hallmundarhraun, a lava field which flowed from an eruption of one of the volcanoes lying under the glacier Langjökull. The waterfalls pour into the Hvítá river from ledges of less porous rock in the lava. The name hraun comes from the Icelandic word for lava. The Hraunfossar are situated near Húsafell and Reykholt and lava-tube cave Víðgelmir is close by.
This image shows an entrance to the "Cloudy Forest Court" (very appropriate on this foggy morning). Beyond the entrance you see a large rock brought from near Lake Tai in China. Known better as Taihu stone (Chinese: 太湖石) this porous stone is produced at the foot of Dongting Mountain (洞庭山) in Suzhou, which is close to Lake Tai. Due to long-term surging by water, this kind of stone features large pores and holes.
This Court also has a display of Penjing - the ancient Chinese art of depicting artistically formed trees, other plants, and landscapes in miniature. This is similar to Japanese Bonsai.

Explored!
Just south of Pescadero, CA, is a small beach locally known as Pebble Beach. Instead of sand it is covered with pebbles that have eroded out of poorly consolidated marine terrace sedimentary deposits in the face of the short bluff at the top of the beach. The rocks that surround and underlie the pebbles are sedimentary rocks. Many of them have this wonderful pattern on them.
This is a weathering pattern known as tafoni. It is likely caused by repeated soaking of porous rock during which small amounts of the rock material dissolves and migrate in solution to the surface of the rock. This results in a gradual weakening of the inner portions of the rock's structure.
Then, as water evaporates from the surface of the rock the dissolved materials remineralize, creating a harder crust-like surface. Eventually that outer crust remains as the inner structure weathers, then erodes away leaving the tafoni structure.
If the new cavities are oriented properly they can capture pebbles that then rattle around in the cavity as waves pass, causing the cavities to grow. But many of these tafoni pockets are not oriented in a direction that would capture pebbles, so that process would not fully explain the pattern.

Traditional Windmills and Houses, after sunset - Oia - Santorini, Greece.
It was extremely gusty while I was in Santorini, so I had to go for the shortest exposure that I could afford. Definitely not the best conditions I was in but in times like these, I always console myself with my favorite Roosevelt quote: "Do what you can, with what you have, where you are.”
It is common to see incave village homes along the cliff of Oia. These houses have been embedded into the porous volcanic rock that was left over from a large volcanic explosion many years ago that sunk the center of the island. The town, noted for its picturesque and mostly blue and white architecture, also combines medieval Venetian houses which used to belong to the captains during the Venetian rule. To maintain and protect the beauty of this unique architecture, there are laws that control modernism of the village. It is no doubt that Oia remains one of the foremost tourist attractions of the Aegean Sea.

Happy Macro Monday. This face (Pareidolia) was found in a hypertufa sphere that has spent several years weathering in Midwestern winters.
The subject of this image bears a remarkable resemblance to a porous sea sponge, floating in the inky black surroundings of the deep sea.
Indeed, the cold, hostile and lonely environment of deep water is not too far removed from deep space, the actual setting for this image in which one of Saturn’s outer moons, Hyperion, can be seen in incredible detail. This image was taken by Cassini when the spacecraft performed a flyby of the small moon on 26 September 2005.
During the flyby, Cassini got more than it bargained for as Hyperion unleashed a burst of charged particles towards the spacecraft, effectively delivering a giant 200-volt electric shock. It appears that Hyperion’s surface becomes electrostatically charged as it is bathed in charged particles – both those constantly streaming out into space from the Sun and those trapped within the magnetic field of the moon’s host planet, Saturn.
While astronomers expected many bodies throughout the Solar System to be charged, the data from the Cassini flyby represent the first-ever experience of a charged natural object in space other than our own Moon.
Hyperion is shaped a bit like a potato and, with dimensions of 410 x 260 x 220 km, is one of the largest bodies in the Solar System known to be so irregular. Its odd, almost ‘bubbly’ appearance, can be attributed to it having a very low density for its size. Because of these properties the entire moon is porous, like a sponge, with well-preserved craters of all shapes and sizes packed together across its surface. Scientists think that this moon is mostly made up of water ice, with small amounts of rock.
Images taken using infrared, green and ultraviolet filters were combined to create this view. The natural redness of Hyperion’s surface was toned down in this false-colour image to enhance the visibility of the moon’s surface features
Cassini was approximately 62 000 km from Hyperion when the image was taken, and the image scale is 362 m per pixel.
The Cassini–Huygens mission is a cooperative project between NASA, ESA and Italy’s ASI space agency.
This image was previously released on the JPL photojournal image archive in September 2005.

international border crossing I have ever seen.......A German - Swiss border crossing point in Konstanz (Constance). The sign marks the actual line. The street and house are both totally within Swiss territory. Without the sign, a stranger to the area would cross an int'l border and not have the slightest inkling. The two governments must calculate that a certain amount of illegal smuggling, etc. takes place at this and similar crossings each year.
The view back down the precipitous path (about 1:1 I would think) up the flank of Coombe Hill.
Any steeper and I'd have climbed it on all fours, but at least it's short.
I like to think I'm super fit for my age (Wow, that's a depressing sentence; to find you've got to the time of life where people say things like that), but I could feel it in my legs for the next two days. The wet spring has left Banburyshire very wet underfoot so I headed south to the porous chalk uplands of the Chilterns and had a good dry day's walk.
Prominent in the image is the wide chalk footpath across the meadow.

It's been several years since I last burned raku. Here I demonstrate the technique to new generations.
Raku ware (楽焼, raku-yaki) is a type of Japanese pottery traditionally used in Japanese tea ceremonies, most often in the form of chawan tea bowls. It is traditionally characterised by being hand-shaped rather than thrown, fairly porous vessels, which result from low firing temperatures, lead glazes and the removal of pieces from the kiln while still glowing hot. In the traditional Japanese process, the fired raku piece is removed from the hot kiln and is allowed to cool in the open air.
The final phase in the Western technique
The Western version of raku was developed in the 20th century by studio potters. Typically wares are fired at a high temperature, and after removing pieces from the kiln, the wares are placed in an open-air container filled with combustible material, which is not a traditional Raku practice in Japan. The Western process can give a great variety of colors and surface effects, making it very popular with studio and amateur potters.

A (roughly) 5 week old saltwater Crocodile basking on a log in the Daintree river in Far North Queensland and a good bit shorter than the one I posted a few days ago.
Young crocs still very vulnerable to other predators including Barramundi!
Not sure if its male or female. The males can grow to 8-10 metres and the females 2.5 - 3m. The sex of the baby croc is determined by water temperature.
The saltwater crocodile is the largest living reptile species of all.. They live for 70-100 years!
One of the amazingly colourful Marine Iguanas from Suarez Point on Espanola
Marine Iguana
The Marine Iguana (Amblyrhynchus cristatus) is an iguana found only on the Galapagos Islands that has the ability, unique among modern lizards, to live and forage in the sea. It has spread to all the islands in the archipelago, and is sometimes called the Galapagos Marine Iguana. It mainly lives on the rocky Galapagos shore, but can also be spotted in marshes and mangrove beaches. On his visit to the islands, Charles Darwin was revolted by the animals' appearance, writing “The black Lava rocks on the beach are frequented by large (2-3 ft), disgusting clumsy Lizards. They are as black as the porous rocks over which they crawl & seek their prey from the Sea. I call them 'imps of darkness'. They assuredly well become the land they inhabit.” In fact, Amblyrhynchus cristatus is not always black; the young have a lighter coloured dorsal stripe, and some adult specimens are grey. The reason for the sombre tones is that the species must rapidly absorb heat to minimize the period of lethargy after emerging from the water. They feed almost exclusively on marine algae, expelling the excess salt from nasal glands while basking in the sun, and the coating of salt can make their faces appear white. In adult males, coloration varies with the season. Breeding-season adult males on the southern islands are the most colorful and will acquire reddish and teal-green colors, while on Santa Cruz they are brick red and black, and on Fernandina they are brick red and dull greenish. Another difference between the iguanas is size, which is different depending on the island the individual iguana inhabits. The iguanas living on the islands of Fernandina and Isabela (named for the famous rulers of Spain) are the largest found anywhere in the Galápagos. On the other end of the spectrum, the smallest iguanas are found on the island on Genovesa. Adult males are approximately 1.3 m long, females 0.6 m, males weigh up to 1.5 kg. On land, the marine iguana is rather a clumsy animal, but in the water it is a graceful swimmer, using its powerful tail to propel itself. As an exothermic animal, the marine iguana can spend only a limited time in the cold sea, where it dives for algae. However, by swimming only in the shallow waters around the island they are able to survive single dives of up to half an hour at depths of more than 15 m. After these dives, they return to their territory to bask in the sun and warm up again. When cold, the iguana is unable to move effectively, making them vulnerable to predation, so they become highly aggressive before heating up (since they are unable to run away they try to bite attackers in this state). During the breeding season, males become highly territorial. The males assemble large groups of females to mate with, and guard them against other male iguanas. However, at other times the species is only aggressive when cold. Marine iguanas have also been found to change their size to adapt to varying food conditions. During El Niño conditions when the algae that the iguanas feed on was scarce for a period of two years, some were found to decrease their length by as much as 20%. When food conditions returned to normal, the iguanas returned to their pre-famine size. It is speculated that the bones of the iguanas actually shorten as a shrinkage of connective tissue could only account for a 10% length change. Researchers theorize that land and marine iguanas evolved from a common ancestor since arriving on the islands from South America, presumably by driftwood. It is thought that the ancestral species inhabited a part of the volcanic archipelago that is now submerged. A second school of thought holds that the Marine iguana may have evolved from a now extinct family of seagoing reptiles. Its generic name, Amblyrhynchus, is a combination of two Greek words, Ambly- from Amblus meaning "blunt" and rhynchus meaning "snout". Its specific name is the Latin word cristatus meaning "crested," and refers to the low crest of spines along the animal's back. Amblyrhynchus is a monotypic genus in that Amblyrhynchus cristatus is the only species which belongs to it at this point in time. This species is completely protected under the laws of Ecuador. El Niño effects cause periodic declines in population, with high mortality, and the marine iguana is threatened by predation by exotic species. The total population size is unknown, but is, according to IUCN, at least 50,000, and estimates from the Charles Darwin Research Station are in the hundreds of thousands. The marine iguanas have not evolved to combat newer predators. Therefore, cats and dogs eat both the young iguanas and dogs will kill adults due to the iguanas' slow reflex times and tameness. Dogs are especially common around human settlements and can cause tremendous predation. Cats are also common in towns, but they also occur in numbers in remote areas where they take a toll on iguanas.
Espanola (Suarez Point)
Approximately a 10-12 hour trip from Santa Cruz, Española is the oldest and the southernmost island in the chain. The trip across open waters can be quite rough especially during August and September. Española's remote location helped make it a unique jewel with a large number of endemic creatures. Secluded from the other islands, wildlife on Española adapted to the island's environment and natural resources. The subspecies of Marine iguana from Española are the only ones that change color during breeding season. Normally, marine iguanas are black in color, a camouflage, making it difficult for predators to differentiate between the iguanas and the black lava rocks where they live. On Española adult marine iguanas are brightly colored with a reddish tint except during mating season when their color changes to more of a greenish shade. The Hood Mockingbird is also endemic to the island. These brazen birds have no fear of man and frequently land on visitors heads and shoulders searching for food. The Hood Mockingbird is slightly larger than other mockingbirds found in the Galapagos; its beak is longer and has a more curved shape. The Hood Mockingbird is the only carnivorous one of the species feeding on a variety of insects, turtle hatchlings and sea lion placentas. Wildlife is the highlight of Española and the star of the show is the waved albatross. The island's steep cliffs serve as the perfect runways for these large birds which take off for their ocean feeding grounds near the mainland of Ecuador and Peru abandoning the island between January and March. Known as endemic to the island, Española is the waved albatross's only nesting place. Each April the males return to Española followed shortly thereafter by the females. Mating for life, their ritual begins with the male's annual dance to re-attract his mate. The performance can take up to 5 days consisting of a series of strutting, honking, and beak fencing. Once the pair is reacquainted they produce a single egg and share the responsibility of incubation. The colony remains based on Española until December when the chick is fully grown. By January most of the colony leaves the island to fish along the Humboldt Current. Young albatross do not return to Española until their 4th or 5th year when they return to seek a mate. Geographically Española is a classic example of a shield volcano, created from a single caldera in the center of the island. Over the years as the island has moved further away from the hot spot, the volcano became extinct and erosion began to occur. Española's two visitor sites offer an exceptional island visit. Punta Suarez is one of the highlights of the Galapagos Islands. The variety and quantity of wildlife assures a memorable visit. Visitors find migrant, resident, and endemic wildlife including brightly colored Marine Iguanas, Española Lava Lizards, Hood Mockingbirds, Swallow Tailed Gulls, Blue Footed and Masked Boobies, Galapagos Hawks, a selection of Finch, and the Waved Albatross.Found on the western tip of Española, Punta Suarez offers great wildlife such as sea lions, sea birds and the largest marine iguanas of Galapagos. This is one of the best sites in the Galapagos. The amount of wildlife is overwhelming. Along the beach there are many sea lions and large, colorful lava lizards and marine iguanas. As you follow the trail to the cliff's edge masked boobies can be found nesting among the rock formations. After a short walk down to a beach and back up the other side blue-footed boobies are seen nesting just off the trail. The Galapagos Dove and very friendly Hood Mockingbird are commonly found in this area. The nearby bushes are frequently home to the large-cactus finch, warbler finch, small-ground finch and large-billed flycatcher. Continuing down the trail you come to the only place where waved albatross nest in the islands. Some 12,000 pairs nest on Española each year. The feeling is very dramatic and it seems like a desolate wilderness as the waves crash on the jagged cliffs below and the blowhole shoots water 50-70 feet/15-30 meters into the air. The sky above is full of sea birds including red-billed tropicbirds, American Oystercatchers, swallow-tailed gulls, and Audubon's Shearwaters.
Galapagos Islands
The Galápagos Islands (official name: Archipiélago de Colón; other Spanish names: Islas de Colón or Islas Galápagos) are an archipelago of volcanic islands distributed around the equator in the Pacific Ocean, some 900 km west of Ecuador. It is a UNESCO World Heritage site: wildlife is its most notable feature. Because of the only very recent arrival of man the majority of the wildlife has no fear of humans and will allow visitors to walk right up them, often having to step over Iguanas or Sea Lions.The Galápagos islands and its surrounding waters are part of a province, a national park, and a biological marine reserve. The principal language on the islands is Spanish. The islands have a population of around 40,000, which is a 40-fold expansion in 50 years. The islands are geologically young and famed for their vast number of endemic species, which were studied by Charles Darwin during the voyage of the Beagle. His observations and collections contributed to the inception of Darwin's theory of evolution by natural selection.
The Trou de Fer ("Iron Hole") is a canyon on Reunion Island, off the coast of Madagascar in the Indian Ocean. The primary river flowing through the gorge, which is up to 300 m (1,000 ft) deep, is the Bras de Caverne River, a tributary of the Rivière du Mât. The canyon has two distinct parts: a large crater, which is fed by six prominent waterfalls, and a narrow slot canyon at its outlet, which constitutes most of the canyon's length. The canyon starts at the waterfall of the Bras Mazerine stream and after some 1.4 - 1.8 km from the left side joins the main Bras de Caverne stream. The Bras de Caverne River enters the canyon with a waterfall about 200 m (660 ft) high. This drop is usually dry or has very little water, but between that and the next, 180-metre (590 ft) drop, springs feed the river, which drops over this then drops over a final 300-metre (1,000 ft) undercut cliff into the Trou de Fer in a narrow plume of water.
Directly to the left of this waterfall, another stream drops over the cliff, which is undercut to an extent that its lip has over 200 m (660 ft) of empty space between it and the canyon floor, of approximately the same height in two channels, and slams onto a ledge before emptying into the same pool as the Bras de Caverne waterfall. This waterfall is not as high, and has a smaller water flow. It is fed by several other falls streaming off the cliffs above it. Further to the left, at about twice the distance from the first falls to the second, another large stream plunges into the canyon. In total, there are at least six waterfalls feeding the canyon. At the base of the canyon, a separate slot canyon, or "The Narrows", begins. The water from the Bras de Caverne waterfall and the waterfall to its left drain into the slot canyon at a 90-degree angle, through a waterfall known informally as the "Washing Machine". The name stems from the mist it generates, which drenches people who stand near the base of the falls.
The slot canyon, or "The Corridor", extends for about 3 km (1.9 mi), and is said to be commonly dammed up by debris jams to form lakes, including the "Lake of the Eel". Many springs flow through the porous volcanic rock of the walls, creating countless waterfalls.
This canyon was first climbed down/walked/swum by Pascale Lapoule, Laurent Broisin and Pascal Colas on 19–21 September 1989.

Das Trou de Fer ist eine etwa 250 Meter tiefe, kesselartige Schlucht auf der Insel Réunion. Der Name dieser geologischen Besonderheit (deutsch: Eisenloch) ist jedoch vermutlich eine sprachliche Fehlüberlieferung und lautete ursprünglich Trou d'enfer (etwa Höllenloch), da es in der Umgebung weder eisenhaltige Gesteine noch Hinweise auf Erzverhüttung (Schmelzöfen) gibt.
Das Trou de Fer liegt an einer Bergflanke im Nordosten der Insel. Das Innere ist nicht zugänglich. Über Wanderwege ist eine Aussichtsplattform am südlichen Rand des Kessels erreichbar, der Blick in die Tiefe ist jedoch häufig durch Nebel und Wolken getrübt. Touristisch erschlossen ist es außerdem durch Überflüge mit Helikoptern und Ultraleichtflugzeugen.
Die sechs von verschiedenen Seiten über mehrere hundert Meter herabstürzenden Wasserfälle erzeugen ein sehr lautes Dröhnen.
Der größte Wasserfall wird durch den Bras de Caverne gespeist, der auch den Abfluss bildet. Durch eine 3,2 km lange, bis zu 850 Meter tiefe und nur wenige Meter breite, schlitzförmige Schlucht, genannt Corridor, fließt er in den Rivière du Mât. Die erste vollständige Begehung entlang des Bras de Caverne durch das Trou de Fer und durch den Corridor gelang Pascale Lapoule, Laurent Broisin und Pascal Colas vom 19. bis zum 21. September 1989.

The Iberian pond turtle (M. leprosa leprosa) is relatively easy to see as you walk between summer pools of winter rivers. Over the scrub and vale, land tortoise also exist, even if they are extremely difficult to see, with the relatively small Hermann's tortoise (T. h. hermanni) being the native species to these areas of eastern Spain. Tortoises make vivid pets for families and children and companions are a human emotion and not a modern invention.
Great expanses of the landscape aside Spain and Portugal converse as rounded 'Tors' and expanded 'Sidobre-esque' outscrops. To the west of Cáceres, the park known Los Barruecos takes the monolithic themes seen elsewhere and plays them with a narrative urgency. A lake held by the non porous granite is framed by monoliths, some that look like essential progenitor life forms, others like natural theatres. The above monolith looks like a tortoise and is part of a cluster that includes carved interventions by man. The carved interventions are behind in this image and include a single monolithic sarcophagus and what might be described as an alter. With evidence of neolithic cups and canals, an adjacent neolithic village and neolithic rock art all practically within sight, the desire to see the interventions around the tortoise rock as being early medieval or iron age may miss out on a gradual rise that continued up into the early medieval ages.
Man lives aside animals. He domesticates some and seeds stories and heuristics through others. Animals are born and animals die, and all members of the life force were part of an animist theatre of spiritual life. Folk lore stores data, and again and again the tortoise outlasts other species, and as an animal it is simply a perfect symbol of longevity and stability (naturally ignoring modern popular culture and its 'mutant' role models). Independence, prudence and calm: slow to procure and last in the race of animals.
The simplest question can be asked: the fact that the monolith looks like a tortoise is inescapable - how could a neolithic village miss the cultural associations?
When all relevant elements from Los Barruecos are added up, is a 'neolithic village' the best term; perhaps the stones were too vivid to demand the addition of menhir or dolmen, and perhaps the term 'natural megasite' may be used?
Whilst monolithic sarcophagi existed in the early interface between local tradition and Christianisation, I am finding recurring evidence of examples associated with vivid stones and outcrops rather than church buildings.

This one was taken in the Cotswold village of Broadway, where there are a lot of these cottage garden flowers. They really are lovely especially in this sort of setting.
The Cotswolds is an area of England which is an escarpment of Oolitic Limestone (or Eggstone) and most of the houses are built with this stone, hence they all have this creamy yellow colour. The stone is actually porous and since the roofs are usually made of the same stone, they have to slope steeply to let the water run off before it soaks through. It is a very picturesque area of England.

permeability (noun): ability of a substance to allow another substance to pass through it, especially the ability of a porous rock, sediment, or soil to transmit fluid through pores and cracks

I remember learning about the cell membrane in my ninth grade high school biology class.
according to definition: "the cell membrane forms a barrier between the inside of the cell and the outside, so that the chemical environments on the two sides can be different. the cell controls those differences so as to optimize the workings of the chemical machinery inside the cytoplasm. the cell also causes brief changes in the internal environment by moving stuff across the membrane in a controlled way. these changes are the ways in which cell respond to events in the outside world."
I think we have membranes too, with differentiating permeabilities. we let ourselves feel in varying amounts depending on the situation, our mood, and other factors. this is about letting oneself "feel the rain" so to speak, when appropriate. and just as importantly, it's about knowing when to catch yourself from drifting too deep: drowning.
The Lake Wales Ridge, sometimes referred to as the Mid-Florida Ridge, is a sand ridge running for about 100 miles south to north in Central Florida. Clearly viewable from satellite, the white sands of the ridge are located in Highlands County and Polk County, and also extend north into Osceola, Orange, and Lake Counties. It is named for the city of Lake Wales, roughly at the midpoint of the ridge. The highest point of the ridge is Sugarloaf Mountain, which at 312 feet (95 meters) is also the highest natural point in peninsular Florida. (The highest point of land, at 371 ft (113 m), is a manmade mining tank west of Bartow.) Iron Mountain, the location of Bok Tower, marks another well-known high point on the ridge, attaining an elevation of 295 ft (90 m). A northern unconnected extension of the Lake Wales Ridge exists in western Putnam County near the town of Grandin.
Origins
Florida's ancient sand islands stretch for over 100 miles down the middle of central Florida. Glacial changes and the rising and falling of the oceans caused dramatic transformations on the Florida peninsula. Covered almost completely by water two million years ago, only a series of small islands existed. It is the remnants of those islands that make up today's Lake Wales Ridge. Although the waters have receded, the islands continue to support distinctive life forms found nowhere else. Today several communities are located inside the Lake Wales sand ridge, with the glaring white sands visible in many neighborhoods.
Habitat
These relic sand dunes created over thousands of years by the dynamic movements of sea, ice and wind now provide refuge for rare and endangered plants and animals. Although consisting of a variety of habitats from low and wet bayheads to high and dry sandhills, the ridge is most famous for its scrub habitat. Wildlife and plants once isolated on these islands evolved extremely unusual characteristics. This forest in miniature consists of clusters of shrubs scattered between patches of open sand. The lack of canopy cover and very deep porous sands create a hot, dry, desert like habitat. Due primarily to a long period of isolation, plants and animals that live on the Ridge have developed ways to deal with their harsh environment.
One of the scrub's best known residents is Florida's only endemic bird, the Florida scrub-jay. When walking through scrub areas, small scrub lizards often race off in the distance — perhaps an adaptation for crossing the hot sand quickly. Many animals of the scrub spend much of their lives underground to escape the hot Florida sun as well as to avoid predators. The gopher tortoise digs a burrow underground that may be up to ten feet deep and up to 30 feet long. More than 360 species may share the gopher's burrow. Other small animals such as the sand skink leave only "S"-shaped tracks as it "swims" just beneath the surface of the sand. It is the only known sand-swimming skink in North America and occurs in only seven counties in Florida.
Most of the vegetation in the Lake Wales Sand Ridge consists of (or has evolved into) scrub plants with thick waxy coated leaves that are drought tolerant. The leaves of the sand live oak are thick and leathery, rolled in at the edges to help retain as much water as possible during the blazing hot days of summer. Species of Opuntia, Yucca, Scrub plum, and scrub Serenoa repens palm dot the landscape and are well adapted to the hot sun and fast draining soils.
In the early twentieth century parts of the ridge were converted to citrus groves. More recently, some of the citrus groves, particularly in the north of the ridge, have been redeveloped for residential housing. Today several areas of the Ridge are protected National Wildlife Refuges and State Forest.

A Swimmer sits under Turner Falls in Murray County near Davis, Oklahoma.
Mazeppa Thomas Turner discovered this waterfall near where he and his wife settled along Honey Creek in the Arbuckle Mountains in Oklahoma in 1868. The waterfall bears his name though it was known and probably used for swimming by the native people of the area long before Turner found it. Born in Virginia to Scottish parents, Turner migrated to Oklahoma where he married Laura Johnson, a Chickasaw. Together they built a successful farm and raised a family on the banks of Honey Creek in Murray County. Must have been nice to have a beautiful swimming hole and 77 foot high falls nearby. In 1919, the city of Davis created a park around the falls which makes it the oldest public park in Oklahoma. In 1925, the city bought 325 acres from the Turners to add to the Park. With the additional acreage the park grew to 1500 acres. The city operated the park until 1950, leased it out from 1950 to 1978, but since then has operated it as a public recreation area.
The park gives good insights in to the geology of the Arbuckle Mountains. There are 3 natural caves in the park plus outcrops of limestone, sandstone, conglomerate, shale and granite. Calcium carbonate, called tufa, forms the distinctive cone the falls cascades over. Tufa is a variety of travertine formed by carbonate minerals that precipitate out of usually ambient temperature water. Though considered by some as a type of travertine, some geologists, however, separate tufa and travertine because the later forms in hot, geothermally heated water and is generally less porous.

This composite photo shows the Twin Rockets to Investigate Cusp Electrodynamics, or TRICE-2, that were launched at 3:26 and 3:28 a.m. EST, Dec. 8, 2018, from the Andoya Space Center in Andenes, Norway. The motors firing on the sides of the first stages spin the rocket to assist in stabilization during flight.
Preliminary data show that the two four-stage Black Brant XII rockets performed nominally and good science data was received from both flights.
TRICE-2, from the University of Iowa, is exploring magnetic reconnection, the explosive process that allows charged particles from space to stream into Earth’s atmosphere. The results promise to shed light on the fundamental process of magnetic reconnection and, in the long run, help us better predict how and when Earth’s magnetic shield can suddenly become porous and let outside particles in.

Here's a macro of a sandstone flag in my garden with a close-up of a tiny sprinkle of building sand. I deliberately selected an area of the flag that had a tiny pit in it.

This is a small Raku pot by artist Jeremy Diller of CA, USA. " Raku Pottery is a type of Japanese pottery that is traditionally hand-shaped. Low firing temperatures, lead glazes and the removal of pieces from the kiln while still glowing hot produce a finished product that is porous. Each piece of pottery is unique and with variations in color and patterns. " I bought this piece on my first solo trip to the west; attracted by the color, texture and the difference between the raku and crackle glazes.
NASA scientists have found evidence that Mars’ crust is not as dense as previously thought, a clue that could help researchers better understand the Red Planet’s interior structure and evolution.
A new map of the thickness of Mars’ crust shows less variation between thicker regions (red) and thinner regions (blue), compared to earlier mapping. Read more: go.nasa.gov/2f7bxiw

One Kleomenous on the Lycabettus hill of is the first building in the portfolio of Omniview by the architect Dimitrios Tsigos. It is a revolutionary new concept of a living space created to showcase his team’s development capabilities, based on cutting edge design and construction techniques and technologies and it carries the strength, beauty and functionality of high quality.
The choice of Travertino marble was in fact very rational is in hamony with the colour characteristic beige stones which are the main building block for all of lycabettus’s retaining walls. From the beginning of the project, the intensity of the building’s visual relatioship with the Acropolis had marbles on moodboard. Marble is a stone in its self, just one that allows more flexibility in its manipulation. Travertino was a perfect match in colour, but also a material that communicates very intensly its non artificial status due to its porous nature. Moreover, it is a very popular material in the sourrounding areas 70’s modernist style condo developments; in fact its also used inour adjuscent building, the one that tie us to the urban tissue.

On July 19th 2013, Toronto experienced what meteorologists call a “severe weather event.” The storm’s high winds led to more than 1,400 calls to the city about downed trees, branches and other damage. Sadly, one of the calls was about a silver maple at 62 Laing Street in Toronto.
This tree, around 170 years old, is said to have been the inspiration for the song The Maple Leaf Forever, written by Alexander Muir in 1867.
No ordinary song, The Maple Leaf Forever was at one time Canada’s unofficial national anthem. Today it is the authorized regimental march of the Queen’s Own Rifles of Canada and the Royal Westminster Regiment.
The City of Toronto decided to commemorate the tree and its place in Canadian history by utilizing every piece of it. Heritage groups and art organizations approached the city with proposals. Our Association was one of the first such groups to step forward. OWCA was given a section of the tree’s main branch about seven feet long and thirty inch at the bottom. The piece has character: it was a cozy home for a raccoon family, has some holes, and in some places the usable wood is less than one inch thick.
But carvers recognize imperfections like these as creative challenges. Our artistic approach features 35 maple leaves, each containing a relief carving of an important person, place or event in Toronto’s history. Historians from Archeological Services Inc.and Heritage Toronto assisted us to choose subjects.
The trunk was debarked, cleaned up, then moved inside at the Ontario Science Centre. Carving officially began on Canada Day, July 1st, 2014. Volunteers from the Ontario Wood Carvers Association completed the project and the finished sculpture was unveiled at a well attended ceremony in 2017. The sculpture is now on permanent display at the Science Centre.

Formed by a waterfall at the end of the last ice age, the porous limestone now means that rainwater soaks into the ground in the hills above the cove and it is very rare that any water comes over the cliff.
Lately I've come to the conclusion that a few clouds can actually make a Milky Way photo more dramatic - rather than detracting from it. It was a bit more cloudy this night than it was when I shot the other panorama from here that I recently posted. The really bright area of light pollution to the left is from the Searles Valley Minerals soda ash processing plant. Judging from the number of abandoned homes and business in town, the plant likely employs far fewer people these days than it once did.
This panorama was stitched together from 23 vertical frames shot with my Canon 6D and Sigma 15mm EX DG at 25 sec f/2.8 ISO 3200.
The Trona Pinnacles are an unusual geological feature in the California Desert National Conservation Area. The unusual landscape consists of more than 500 tufa spires (porous rock formed as a deposit when springs interact with other bodies of water), some as high as 140 feet (43 m), rising from the bed of the Searles Lake (dry) basin. The pinnacles vary in size and shape from short and squat to tall and thin, and are composed primarily of calcium carbonate (tufa). They now sit isolated and slowly crumbling away near the south end of the valley, surrounded by many square miles of flat, dried mud and with stark mountain ranges at either side.
The Pinnacles are recognizable in more than a dozen hit movies. Over thirty film projects a year are shot among the tufa pinnacles, including backdrops for car commercials and sci-fi movies and television series such as Battlestar Galactica, Star Trek V: The Final Frontier, Disney's Dinosaur, The Gate II, Lost in Space, and Planet of the Apes.
After a night of rain, I was hoping to see more than a trickle flowing here, but no such luck. With the porous limestone in the area, these falls require several days of steady rain to show any decent flow at all.
But the waterfall formation itself is very impressive. The tufa was formed by calcite precipitating out of the water here for thousands of years.
I also want to return for the wildflowers. I saw hundreds of thousands of trout lily leaves poking up, as well as numerous other wildflowers emerging through the leaf litter.

The 'Agoranomeion', a mysterious fragment of the past
The identification of this public building is not yet ascertained. It was built with porous ashlar masonry higher than the level of the east propylon of the Roman Agora. A wide staircase leading to a facade with three archways and parts of the north and south walls are preserved.
Located on the east side of the Roman Agora, with a triple arched entrance, it is so far unidentified. Initially it was thought this was the Agoranomeion - the headquarters of the market inspectors - but today it is thought it was possibly a temple dedicated to an emperor or deity.
According to the inscription on the epistyle of the facade the building was dedicated to Athena Archegetis and the divi Augusti (middle 1st c. A.D.)
Hraunfossar (Borgarfjörður, western Iceland) is a series of waterfalls formed by rivulets streaming over a distance of about 900 metres out of the Hallmundarhraun, a lava field which flowed from an eruption of one of the volcanoes lying under the glacier Langjökull. The waterfalls pour into the Hvítá river from ledges of less porous rock in the lava. The name hraun comes from the Icelandic word for lava. The Hraunfossar are situated near Húsafell and Reykholt
In ‘The Genesis Exhibition: Do Ho Suh: Walk the House’, Korean-born, London-based artist Do Ho Suh invites visitors to explore his large-scale installations, sculptures, videos and drawings in this major survey exhibition.
Is home a place, a feeling, or an idea? Suh asks timely questions about the enigma of home, identity and how we move through and inhabit the world around us.
With immersive artworks exploring belonging, collectivity and individuality, connection and disconnection, Suh examines the intricate relationship between architecture, space, the body, and the memories and the moments that make us who we are.

Nest/s (2024)
Nest/s is connected to an ongoing fabric architecture series Suh calls ‘Hubs’. They form what he describes as an ‘impossible’ architecture. The Hubs serie is based on threshold, such as corridors or entryways, from spaces Suh has occupied throughout his life. In Nest/s, each section is drawn from rooms Suh has inhabited, which together create a continuous passageway. Unlike most building materials, the translucency and delicacy of the textile conveys impressions of the original space rather than acting as a precise replica. The work is made through centuries-old techniques of working with fabric in Korea. The polyester material is today used for traditional Korean summer clothing, emphasizing Suh’s interest in the relationship between architecture and the body. Nest/s breathable and porous quality allows in the surroundings of the museum and the sight of visitors passing through it, blurring the boundaries between inside and outside? Suh considers the fabric architectures to be ‘activated’ once occupied.
