Formations showing Polygonal Cracking at Vermilion Cliffs National Monument, Arizona.
This image is part of my Southwest set.
From the parking area sign:
This area is a spectacular exposure of red, pink, and white contorted sedimentary rock layers. The bedrock here consists of the Early Jurassic age Navajo Sandstone. The Navajo Sandstone is composed of frosted, well-rounded, fine-to medium-grained quartz cemented by calcium carbonate.
Approximately 190 million years ago, this area was part of a region covered with deep, shifting sand and complex dunes comparable to the modern day Sahara Desert. The dune field encompassed parts of Arizona, Utah, Nevada, Colorado, and Wyoming. The large-scale, high-angle, crossbeds, which can be up to 25-feet wide are characteristic of windblown deposits and are examples of what was once a large dune field.
At that time, periods of monsoonal moisture supported plant and animal life. Organisms left evidence of their existence in this area in bio-turbated beds. Bio-turbation in this area is caused by the mixing of sediments by ancient, burrowing insects and spiders.
The various shades of red, pink, yellow, and brown rocks are due to the oxidation of iron-bearing minerals within the sandstone. The red and pink colors are attributed to the presence of the mineral hematite, while the yellow and brown colors are produced by the minerals limonite or goethite.
The beautifully swirled appearance of the rocks are due to an exceptional exposure of unusually soft sediment deformation and slump sediments. Soft sediment deformation occurs when separated layers of sediment are flooded and/or sheared due to gravitational forces, changes in ground water, or earthquakes.
Thick, massive beds have characteristic polygonal cracks produced by tensile stress and exposed by weather processes. Many theories exist regarding the origin of polygonal cracks, including thermal contraction, moisture cycles, and the drying process of these sediments.

Just wormed its way into EXPLORE - 332rd place.... Thank You All! It is probably only a quick passage and I just caught it....!!!
I confess, I love doing Sudokus, and I love nuts, any nuts, as long they are free of worms.... I don't like walnuts as much as I love pecans, but since all nuts are said to be good for your brain, I thought; walnuts have the form of a brain (sort of....), so out they came from their bag! I happily crunched and munched them, but funnily, they didn't do ANYTHING at all for my Sudoku skills! I also - at this place - confess that I am absolutely useless in math...., so doing Sudoku is a bit like a survival skill for me.... :)
I did this photo for the fun, it's a hot day today, the work in the house drives me crazy, but mostly I did this for the Two Word Wednesdays group! :)

My FLICKR DNA
Yes, I had a brain explosion and took a selfie! Taken during the new years fireworks display at Port Fairy around nine or ten years ago. (It didn't hurt a bit!) ; )
I've been planning to build something like this since a while, the Hydra 8-wheeler ispired the build.
At the Saturday March For Science, several people were wearing these brain caps or thinking caps to symbolize the importance of critical thinking in science. I added several more from this march.

Kong Ming lock is a traditional Chinese intellectual toy. It is said that the toy was invented by Zhu Ge Kong Ming some 2,000 years ago based on the principles of the eight-diagram metaphysics. It was widely popular among the folks. The concave and convex parts inside the three-dimensional interpolation toy mesh perfectly. Kong Ming locks come in different shapes and sizes, with different internal structures. But they are usually easy to take apart and difficult to reassemble.
Do you enjoy brain teasers?
From deep underground and from a long way inside the Tupperware Storm Drain we create a Brain of light by waving our little l.e.d wands of coloured lights around like its a dance festival
Brain coral is found around the globe and comes in many varieties. This one is either the grooved or the maze kind. Brain corals extend their tentacles to catch food at night. During the day, the brain corals use their tentacles for protection by wrapping them over the grooves on their surface.

Mulberry Brain fungi (Tremella moriformis) is a parasitic jelly fungus. Seen here on a dead beech tree.
Very small - this example measured no more than 5mm in height.
Clumber Park, Notts.
Mirrored image of a brain from a mouse with the neurodegenerative disease Niemann-Pick type C1 (NPC1). A major way to assess the impact of a potential therapeutic on the central nervous system is to assess cerebellar pathology in mice. Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) researchers found that an experimental drug could stabilize or slow the progression of NPC1.
