"Sandstone Coloration is:
• A function of varying amounts of iron (mineral hematite - Fe) that imparts red color.
• Initially red, soon after sand grains are deposited and buried.
•Red where thin scattered films of hematite coat sand grains, and white where the thin films of hematite have been removed by bleaching.
• Facilitated by how easily fluids can move through a sandstone due to different textures of the sandstone (e.g., how loosely or tightly sand grains are packed together).
•Variable even on a scale of fractional inches where thin red
layers alternate with white layers.
This is again a function of microscopic textures in the sandstone.
•Affected by oxidizing fluids thatencourage hematite precipitation (red color) as well as reducing fluids that bleached the sandstone by removing the hematite (white color).
•A property that may have changed over time and involves
fluids and processes that occur over tens of millions of years. "

What colors the sandstone red? The red color is caused by a union of iron and oxygen (an iron oxide) known as hematite (Fe 2 O ), a mineral named from the Greek word for blood. Iron is a powerful pigment present in many sediments and rocks, thus it commonly imparts color to the rocks.
Although red is the common pigment color, not all iron oxides are red; some are brown or yellow (minerals - limonite or goethite), and some are black (mineral - magnetite). Some iron minerals are metallic yellow (mineral - pyrite consisting of iron sulfide) or green (minerals - chlorite or clay consisting of iron silicate)."

The DeGolyers lived at Rancho Encinal near Dallas. The 1940 estate, located on the shores of White Rock Lake, would later become the permanent location of the Dallas Arboretum and Botanical Garden. Everette Lee DeGolyer (October 9, 1886 – December 14, 1956), was a prominent oilman, geophysicist and philanthropist in Dallas. He was known as "the founder of applied geophysics in the petroleum industry", and as "the father of American geophysics".
The 21,000-square-foot home of Mr. and Mrs. Everette DeGolyer serves as the centerpiece to DeGolyer garden in the Dallas Arboretum. Landscape architects Arthur and Marie Berger designed the 4.5-acre DeGolyer Gardens in 1940. The DeGolyer House is listed on the National Register of Historic Places as well as the Texas Register of Historic Places, and is open daily for tours.

Rice was first domesticated in China around 10,000 years ago. "Such an age for the beginnings of rice cultivation and domestication would agree with the parallel beginnings of agriculture in other regions of the world during a period of profound environmental change when the Pleistocene was transitioning into the Holocene," Lu Houyuan, professor of the Institute of Geology and Geophysics at the Chinese Academy of Sciences, said. The research, published in the Proceedings of the National Academy of Sciences USA, was done in collaboration with Zhejiang Provincial Institute of Relics and Archaeology and the Institute of Geographic Sciences and Natural Resources Research at the Chinese Academy of Sciences. From southern China, domesticated rice diffused to South and Southeast Asia. Today, many Asian countries become more rice-dependent than China is. Most Filipino people refuse to eat a meal without rice. That's why even MacDonald outlets in the Philippines have to serve rice.
Badlands erode at self-similar scales. The results can be striking when seen from above in the diffuse light before sunrise.

Ready for a fun, nerdy geology fact? Sure you are! That pyramidal structure in the middle is called a nunatak. I used to have a double-major in comp sci and geophysics, but quit the latter after a fight with a moronic tenured professor. It wasn't a fist-fight... an intellectual one, a fight with which I contend I won. I just studied geophysics it because I love the Earth and I think rocks and landscapes are super-interesting, not because I wanted a job drilling for oil or anything (the career path for many geophysicists... reminds me of a great Alan Watts lecture that it's frowned upon for people to study things in universities unless they are looking to fit a cog in a machine) - anyway, this nunatak was formed when the two glaciers from the Dart and Rees from the left and right side came together to carve out that perfect triangle. Technically, it's not a triangle or pyramid, but a sloping triangular prism... okay nerd talk done. Who cares? It's pretty. Okay, a little more nerd talk... nunatak is one of the only Greenladish words in our lexicon if you're into etymology. I got this on a fun helicopter ride a few weeks ago with Joann and some friends from Over The Top Helicopters.
#3 Exhibition of Achievements of National Economy at Moscow
Scan from my old film taken in 1970y
The exhibition park is a closed green area with a symbolic entrance fee. It was founded in 1935 and was originally dedicated only to the exhibition of advanced machinery and technology in agriculture. In the well-groomed green area of the Park with many fountains there were large monumental exhibition buildings dedicated to different regions (republics) of the state, their agriculture and technology. Own botanic garden, large flower fields. The entire architecture and layout of the park was made in a single Stalin's Empire style. Nothing to do with Disneyland. Already in those days, only electric vehicles were used to move around the Park. Trolleybuses along perimeter of the Park. Those trolleybuses differed from the urban ones almost completely glazed interior (including ceiling). On internal routes used small semi-open road trains with electric traction, even small electric taxis were (for a fee).
In the 60s, the territory of the Park was significantly expanded. The theme of the exhibition began to cover not only agriculture, but all industries. Many new exhibition buildings were built, some of which had faceless modern architecture (glass and steel). So the Park has a bit lost its unique image.
This exhibition complex had its own meat dairy and bakery production. Their products were sold in numerous small cafes and pavilions in the park. These products were incomparably higher quality than what you could buy in ordinary Moscow stores. As I remember, especially fine were hot dogs, coffee with sandwiches or doughnuts and different kinds of hot bread (just out of the bakery). All goods and services were for very small money.
Now it is impossible to buy anything like this here (I'm not talking about luxury restaurants, where I have not been for a long time).
By the way, my equipment was also for a while exhibited there in the exhibition building of Geophysics as an example of student creativity

Cotopaxi is an active stratovolcano in the Andes Mountains, located in the Latacunga canton of Cotopaxi Province, about 50 km (31 mi) south of Quito, and 33 km (21 mi) northeast of the city of Latacunga, Ecuador, in South America. It is the second highest summit in Ecuador, reaching a height of 5,897 m (19,347 ft). It is one of the world's highest volcanoes.
Since 1738, Cotopaxi has erupted more than 50 times, resulting in the creation of numerous valleys formed by lahars (mudflows) around the volcano.
The Geophysics Institute of Quito's National Polytechnic School placed Cotopaxi under active watch on 25 June 2015 after observing activity. Cotopaxi's most recent eruption started on 15 August 2015.
As I looked over the railing on the bridge that crosses the Pelican Creek Wetland along the East Entrance Road In Yellowstone National Park, I was amazed by the star shapes on the surface of the ice on some of the ponds. I had seen these fractal like patterns in ice before. As a boy in Wyoming , I remember wondering how these features form, but after years of wintering in Southern Louisiana and Southern Texas, those memories were buried deep in my onboard computer. As I recalled my boyhood observations, I was left wondering how do these features form? After a quick search of the internet, I found that these features are quite common. Henry Thoreau described such features in Walden. He spent time on the ice in winter and describes how it forms very scientifically. He did take notice of the ice stars which he describes as looking like spiderwebs. His interpretation of how they form is somewhat convoluted and does not fully explain the phenomena. Since Thoreau, several ideas and theories have been offered. In 2007, two geophysicists, Victor Tsai of Harvard University (Now of Brown University) and John Wettlaufer of Yale University, modeled the formation of these star shaped holes in the ice. They determined that the shape is governed by the properties of the snow that covers the ice. Their work suggests that the star patterns are formed when a hole in a recently frozen lake allows water to swell up from beneath and spread over the snow-covered surface, leaving dark “fingers” of melted ice that stem from a central point. Previously, some geologists, physicists and others had suspected that the fingers form if there is a warming trend after the ice forms and snow covers the ice. As the temperature increases, some ice melting occurs. The water starts to upwell and flow in one direction, causing the snow to melt faster in that region and thus helping the water to flow faster. Tsai and Wettlaufer first constructed a simple mathematical model to test this idea. They began by assuming that the rate of flow of the water is dependent on how compacted and thus how porous the snow is. The model also took into account parameters such as the driving pressure and heat content of the water and how fast heat could transfer by diffusion. They found that of these parameters, the snow porosity and maximum driving pressure governed how many fingers extended from the holes. They then built a physical laboratory experiment to test their ideas and ran it numerous times. The mathematical model did not perfectly predict the number of holes developed in the ice in the laboratory experiment but was right 94% of the time (not bad for a model).

Here's a scene from high atop a mountain near the Matterhorn in Zermatt, Switzerland. I like it because it really shows how the glaciers flow and merge like rivers. I've always been into glaciers and rocks and stuff; I used to be a double major in Geophysics and Computer Science. I dropped my double in Geophysics because I had a fight with my moronic professor there at SMU, but even his idiotic prattlings didn't ruin my love of rocks!
