Newberry Volcano is a large active shield-shaped stratovolcano located about 20 miles (32 km) south of Bend, Oregon, United States, 35 miles (56 km) east of the major crest of the Cascade Range, within the Newberry National Volcanic Monument. Its highest point is Paulina Peak. The largest volcano in the Cascade Volcanic Arc, Newberry has an area of 1,200 square miles (3,100 km2) when its lava flows are taken into account. From north to south, the volcano has a length of 75 miles (121 km), with a width of 27 miles (43 km) and a total volume of approximately 120 cubic miles (500 km3). It was named for the geologist and surgeon John Strong Newberry, who explored central Oregon for the Pacific Railroad Surveys in 1855. The surrounding area has been inhabited by Native American populations for more than 10,000 years.

Meteor Crater in Arizona is an interesting National Natural Landmark.

 

Privately owned by the Barringer Crater Company, this 1.2 km diameter, 170m deep hole confounded geologists and speculators alike for nearly 70 years. In the 1890s, mineralogists and geologists investigated meteorites in the area and the crater itself (known then as Canyon Diablo) to determine whether it could have been formed by a meteoric impact - a radical theory at that time. The Chief Geologist for the U.S. Geological Survey, Grove Karl Gilbert, hypothesized that for the crater to have been caused by a meteor would require a meteor the size of the crater, and that the meteorite itself would be buried below the crater, creating a magnetic anomaly. Since he could find no evidence to support his hypothesis, Gilbert, the most respected and prestigious geologist of his time, declared the crater a result of a volcanic steam explosion.

 

Daniel Moreau Barringer, a mining engineer who had made a fortune in Silver, learned about the crater and meteorites around it and became convinced that it was an impact crater. Believing, like Gilbert, that a sizable iron meteor (on the order of ten million tons) must have caused the crater, he began the Standard Iron Company to begin mining the area in hopes of making a billion-dollar fortune. Barringer, and his partner Benjamin Chew Tilghman set about trying to prove the validity of their impact theory, presenting arguments to the Academy of Natural Sciences in Philadelphia and the National Academy of Science in Princeton during the first decade of the 20th century.

 

In the following two decades, Barringer continued mining for the meteor, changing the focus from directly beneath the crater to under the south rim, only to find water. With investors getting nervous about the potential for losing their money, Barringer consulted F.R. Moulton, an astronomer, for his analysis on the size of the meteor. Unfortunately for Barringer, Moulton determined the meteor to be approximately 300,000 tons (3% of Barringer’s speculation), and that the bulk of it would have been vaporized on impact.

 

On November 30, 1929, heartbroken and having lost the bulk of his fortune in addition to the hundreds of thousands of investors' dollars, Barringer died a week after receiving Moulton's most thorough analysis. It took until 1960 when, Eugene Merle Shoemaker identified the existence of coesite - a silica that is only formed by intense over pressurization of quartzite rock - in the meteor crater, finally confirming Barringer's hypothesis of the impact event.

 

In the century since Gilbert's and Barringer's hypotheses, science has advanced considerably in geology and astronomy, to the point where impact craters hundreds of miles wide have been identified across the globe. But, without the pioneering work by Barringer, and his willingness to take on the contemporary scientific establishment (backing Gilbert), little of this would have been realized.

A chilly morning view of the 3 Sisters reflected in Policemen's Creek.

 

"If you have visited the town of Canmore or nearby Banff, you have likely seen or at least heard about the Three Sisters in Canmore. They are easily the town’s most recognizable peaks and some of the most unique in the Canadian Rockies.

 

In 1883, when Canmore was known as a mining town, Albert Rogers named these three peaks the “Three Nuns” following a winter storm that left the peaks snow-capped and resembled nuns in white veils.

 

In 1886, they were renamed by George Dawson, a Canadian geologist, and surveyor, to the Three Sisters. The names of the Three Sisters are individually known as Big Sister, Middle Sister, and Little Sister – or Faith, Hope, and Charity, respectively.

 

Îyârhe Nakoda, the traditional language of the First Nations Stoney Nakoda, also refers to the peaks as the Three Sisters. Although the name refers to Ĩ-ktomnĩ, the old man who would promise ‘three sisters’ in marriage whenever he was in trouble.

 

The Big Sister is the biggest at 2,936 meters, the Middle Sister is 2,769 meters, and the Little Sister is 2,694 meters."

Thanks for taking a look! Always appreciated.

Rocky Cape is aptly named. The range of geological interest here would keep graduate students happy for years. Look at the way those layers of sedimentary rock have been folded into each other, like layers in a cake. The raggedness is also a real feature of the Rocky Cape National Park. There are no smooth granite blocks in this location. Merely evidence of a dramatic volcanic past. And we can see prime evidence of that directly ahead: The extinct volcano at Stanley, "The Nut".

Unfortunately, going back through my photo archives, I can't recall where I took this, or what the rock is / minerals are. Any geologists out there who can help me identify this? Thanks. Whatever it is, I find it to be astoundingly beautiful and wondrous. (Hence my wondering....) ;-)

I'm no geologist, but I find the subject absolutely fascinating photographically. Scientists tell us time is relative. You can get a sense of that standing in a place like this. These rocks, which seem so solid and immovable, are in reality in constant motion. Their twists and turns, invisible to us from our limited human perspective, are written in their striations for all to see. Millions of years of geological time suspended in living rock.

 

I made several close-up studies of these rocks but also this wider view to include the presence of water, one of the main agents of geological change. Nothing was moving when I made my exposures, which meant I could employ focus stacking to maximise the apparent depth of field. But appearances can be deceptive. In many ways, this image is all about movement. I composed it to emphasise the dynamic flowing lines of rock, with the small pool providing a point of stillness where the eye can come to rest.

We found this interesting rocky landscape in Big Bend Ranch State Park, just a few miles from the more well-known Big Bend National Park.

Of greatest interest to me is that rectangular reddish slab near the middle. For perspective, I'd estimate it to be at least as large as ten full size school buses.

Surely broke off from the top of the mountain above but how it tumbled that far without breaking into pieces seems odd.

Knockan Crag (Scottish Gaelic: Creag a' Chnocain, "crag of the small hill") lies within the North West Highlands Geopark in the Assynt region of Scotland 21 kilometres (13 mi) north of Ullapool. During the nineteenth century Knockan Crag became the subject of much debate when geologists noted that the Moine schists at the top of the crag appeared to be older than the Cambrian and Ordovician rocks such as Durness limestone lower down. Disagreements over the processes that could have caused this to occur were referred to at the time as the "Highlands Controversy". The argument was primarily between Roderick Murchison and Archibald Geikie on the one hand and James Nicol and Charles Lapworth on the other. Murchison and Geikie believed the sequence was wrong and that the Moine schists must be the younger rocks. The controversy was finally resolved by the work of Ben Peach and John Horne whose 1907 paper on the subject remains a classic text. Peach and Horne demonstrated that the situation resulted from the action of a thrust fault - this being the first to be discovered anywhere in the world. The older rocks had been moved some 70 kilometres to the west over the top of the younger rocks due to tectonic action.

The crag is designated as a national nature reserve (NNR) due to its geological features and is owned and managed by NatureScot. There is a car park and interpretation centre that explains the geology of the area and gives background to the Highlands Controversy, along with three waymarked trails that take visitors to points of interest across the site. The site also hosts artworks such as 'The Globe' by Joe Smith and 'Pipeworm’ by Susheila Jamieson that were commissioned to highlight the inspiration that the landscape has had on artists and poets.

The Isle of Arran is an island off the west coast of Scotland. It is the largest island in the Firth of Clyde and the seventh largest Scottish island. Often referred to as "Scotland in Miniature", it can be reached by a 55minute ferry crossing from the coastal port of Ardrossan on the mainland. The Island measures 20 X 10miles and is divided into highland and lowland areas by the Highland Boundary Fault and has been described as a "geologist's paradise”, this photo shows some of the coastline and the 2,866ft “Goat Fell” the highest mountain on the Island.

Lake Mungo, dried-up lake and archaeological site in west-central New South Wales, Australia, located in and around Mungo National Park. Lake Mungo is one of 17 dried Pleistocene Epoch (about 2.6 million to 11,700 years go) lake beds in the Willandra Lakes region, which was designated a World Heritage site in 1981.

 

Lake Mungo, which dried up about 14,000 years ago, became one of the world’s most important archaeological sites when geologist Jim Bowler unearthed the remains of a young Aboriginal woman in 1968. The bones of the skeleton, referred to as Mungo Lady, had been burnt before burial, making them the world’s oldest evidence of cremation and ceremonial burial. In 1974 Bowler discovered the complete skeleton of a man, known as Mungo Man. Carbon-14 dating indicated that these remains were approximately 40,000 years old, meaning that Mungo Lady and Mungo Man were the oldest human remains found in Australia to that date.

HMBT!

Led by the Australian geologist we climbed the volcano. With his jeep we drove as far as possible on the slope of the mountain where we then walked through the jungle. There was no hiking trail, but the local guide knew exactly where to go.

In these latitudes the tree line is far higher than in our temperate zones, finally we started the last part of the way, which has been

only loose lava rubble which slipped under our feet. We finally reached the edge of the crater in altitude of 2.892 meters (9,485 ft). The geologist wanted some rock samples.

Ok, parties of geologists come to places like this on holiday. I overheard one of the group leaders saying that the beach is littered with stuff that was spat out by the volcanoes across the sea in Skye. A while ago. So whilst there are plumes of dark volcanic rock thrusting out of the coast, this end of the beach is covered in green algae pebbles and rocks where the freshwater river flows out to the sea, but further back where the sand is pale and fine, is where the black volcanic grit, washed out of the surrounding mountains flows over the 'white' seashell sand to make all the patterns I show elsewhere in my photostream. The shoreline is quite steep, with a deep heap of granite pebbles of varying colours and strata, that rolls back and forward with the tides and sometimes thunderous Atlantic waves crashing into the bay.

 

This is a stitched image of nine frames that didn't quite join up as wonderfully as I had hoped, but you get the picture. Nice grey, cloudy sky. End of the track, fabulous isolated back o'beyond holiday home on the Ardnamurchan Estate at Fascadale, fully equipped with jump leads.

Most of what you see here are part of the bedrock rather than pebbles and boulders. There are times I wish I was a geologist and knew what I was looking at!The rock on the right is more like a conglomerate but I think it has been heated. The rock in the middle and to the left is a good deal smoother and rounded, it reminds me of mud! The boulder is red sandstone (plenty in the area) and the rest are erratics thrown up by the sea, it does get rather stormy here in the winter.

Preikestolen, which was formed more than 10.000 years ago is the most iconic natural landmark in Norway. The cliff was formed during the ice age, approximately 10,000 years ago, when the edges of the glacier reached the cliff. Along the plateau itself there is a deep crack. Due to these cracks, the plateau will at some point fall down, but all the geological investigations have revealed that this will not happen in the foreseeable future, and geologists have confirmed the safety of the plateau.

  

Limestone Pavements create a distinctive and dramatic landscape. The limestone pavement is made up of a series of clints (the flat horizontal slabs of carboniferous limestone) and grykes (the vertical cracks between the slabs). They date back to the ice age when the scouring action of ice sheets exposed the pavements. Since then, water movement has widened the cracks in the pavements to form a complex pattern of crevices.

 

The pavements at Twistleton, just above Ingleton are renowned for their extensive complexity as seen here. Of course I had to include another of the Hawthorn trees that dot the landscape.

Geologists say that Colonnade Arch, or Five Hole Arch, is not an arch at all, but a buttressed alcove, with three windows looking south, and two windows in the ceiling looking up and the the north (one is out of sight in this point of view, deeper in the alcove). This structure is on the rim of the Green River Canyon, overlooking Two Mile Canyon, in a wilderness study area that needs to be upgraded to a wilderness.

Beautiful Cathedral Rock is an example of geological time at work.

 

According to Larry D. Fellows, (Vol. 33, No. 3 FALL 2003, Arizona Geology), the red rock was originally soft mud and sand deposited over a 50-million-year time period that began about 320 million years ago (my mother in law may recall this era - I should ask her). During that time the area was a low, arid coastal plain next to a shallow sea.

 

Rivers, wind, ocean waves and currents deposited sediment at different times. Sea levels rose and layers of mud accumulated on the sea floor on top of the river deposits. Sea levels fell resulting in wind-blown sand and dunes.

 

As time passed the sediment changed to hard rock. The red color is caused by a thin coating of iron oxide.

Coming to Arunachala, an unknown American geologist is famed to have said "Arunachala should have been thrown up by the earth under the stress of some violent volcanic eruption in the dim ages before even the coal-bearing strata were formed. This rocky mass of granite may be dated back to the earliest epoch of the history of our planet's crust, that epoch which long preceded the vast sedimentary formation in which fossil records of plants and animals have been preserved. It existed long before the gigantic saurians of the pre-historic world moved their ungainly forms through the primeval forests that covered our early earth. It was contemporaneous with the formation of the very crust of earth itself. Arunachala was almost as hoary and as ancient as our planetary home itself"

From this we can place his analysis to mean that Arunachala was perhaps 'born' in the Hadean/Archean period which ranges from 4.4 to 3-8 billion years.

 

Geological experiments in and around Tiuvannamalai have revealed that the rock (charnokite) which makes up Arunachala covering is older than 3.5 billion years old ( Geological Survey of India) and banded Iron formations around Tiruvannamalai area are thought to be about 3 billion years old.

 

(Mineralogy and chemistry of banded iron formations (BIF) of Tiruvannamalai area, Tamil Nadu,Journal of Earth System Science,Volume 98, Number 2 / July, 1989.)

 

It is thus evident that even scientific conclusions do place Arunachala Age to be beyond 3.5 billion years and perhaps the range would be 4.4 to 3.5 billion years old.

 

In lay man's terms, Arunachala can be as old as the Earth itself!

"In July, 1955, Harry Feather, geologist at Wichita Falls, Texas, notified the director of the University of Oklahoma Museum of his recent discovery of a Spanish arrastra in the Wichita Mountains of Southwestern Oklahoma. Mr. Feather supplied a crudely drawn map of the approximate site and suggested that the Museum consider restoring it as a coatribution to the early history of the region. Nothing was done about following up the suggestion until June, 1956, at which time this writer and Dr. Sherman Lawton, archaeologists by avocation, set out for the Mountains on a brief exploratory venture. "

 

After failed attempts from a crudely drawn map, the archaelogists enlisted the help of a ranger who had seen the arrastra. It's location is still not marked, but with some decent directions and google maps with a weak cell signal, I was able to locate the site. Arrastras were crude ore mills.

ENGLISH CAPTION: "The Geologist" One of the thing I like the most about my work as a geologist, are probably those countless hours you spend in the field walking, and watching the rocks and the landscapes... Those weeks that you spend working under the sun tend to change the way you percieve your surroundings, and then photography becomes the best language to communicate what you see...

The Grand Canyon is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).

 

The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. The surrounding area is contained within the Baaj Nwaavjo I'tah Kukveni – Ancestral Footprints of the Grand Canyon National Monument. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery.

 

Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While some aspects about the history of incision of the canyon are debated by geologists, several recent studies support the hypothesis that the Colorado River established its course through the area about 5 to 6 million years ago. Since that time, the Colorado River has driven the down-cutting of the tributaries and retreat of the cliffs, simultaneously deepening and widening the canyon.

 

For thousands of years, the area has been continuously inhabited by Native Americans, who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon a holy site, and made pilgrimages to it. The first European known to have viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540.

Grand Canyon National Park is a national park of the United States located in northwestern Arizona, the 15th site to have been named as a national park. The park's central feature is the Grand Canyon, a gorge of the Colorado River, which is often considered one of the Wonders of the World. The park, which covers 1,217,262 acres (1,901.972 sq mi; 4,926.08 km2) of unincorporated area in Coconino and Mohave counties, received more than 4.7 million recreational visitors in 2023. The Grand Canyon was designated a World Heritage Site by UNESCO in 1979. The park celebrated its 100th anniversary on February 26, 2019.

 

Source: www.nps.gov/grca/index.htm

 

Entirely within the state of Arizona, the park encompasses 278 miles (447 km) of the Colorado River and adjacent uplands. Located on the ancestral homelands of 11 present day Tribal Communities, Grand Canyon is one of the most spectacular examples of erosion anywhere in the world—a mile deep canyon unmatched in the incomparable vistas it offers visitors from both north and south rims.

I'm geologist and I workes 5 sumnmer in Labrador Trough for geological mapping and metallogenic reserach for National Institute of Scientific Research of Quebec.

 

Colorized by me from B&W photo (Ilford Pan F 50 ASA)

 

The Labrador Trough or the New Quebec Orogen is a 1,600 km (994 mi) long and 160 km (99 mi) wide geologic belt in Canada, extending south-southeast from Ungava Bay through Quebec and Labrador.

 

The trough is a linear belt of sedimentary and volcanic rocks which developed in an Early Proterozoic rift basin. To the west is the Archean Superior Craton. To the east are the rocks of the Archean Rae Craton. The sedimentary rocks and volcanics of the Labrador Trough were intensely deformed and subjected to high grade metamorphism along with the Churchill terrain during the Trans-Hudson orogeny.[1] It is a northeast extension of the Circum-Superior Belt and is terminated to the south by the Grenville Front Tectonic Zone.

 

Radiometric dates of 1883-1870 Ma are reported for mafic, ultramafic, carbonatite and lamprophyre intrusions within the Trough.

 

It is a large iron ore belt developed on banded iron formations and has had mining operations since 1954.

 

At least two large magmatic events occurred in the Labrador Trough. The first event 2,170 million years ago engulfed an area of 30,000 km2 (12,000 sq mi) and the second 1,880 million years ago covered a similar area of 30,000 km2 (12,000 sq mi).

This beach is famous to geologists because it is a good example of how different rock types erode. The arch is made of hard limestones so it is eroding very slowly. But the soft coloured clays in the middle of the picture are cut out very quickly by the waves, making the curved shape of the beach. And the chalk you see in the foreground forms hard wall at the back of the beach, which stops it from expanding too quickly, although there can be spectacular rock falls.

Such a bereft geologist,

Delving surface-deep

She renders hearts of fool’s gold

Backpacked here and there

As reciprocal gifts

She’s employing meek magic; Mines

That few see

Even in the hundreds, she claims,

As bragged sediment

Interestingly this is a man made waterfall. As strange as this may sound geologists and historians have discovered that the river Öxará was moved hundreds of years ago, to channel the water into the ravine Almannagjá in the ninth century. The purpose was to provide water for the members and visitors of the Icelandic parliament Althingi in the 9th century.

What was a treasure for geologists, turned out to become a treasure for picture hunters.

 

I'm so jealous of you basques!

Geologists suggest this is a granite bubble from deep down that has been thrust upwards. As the layers have eroded and the compression on the rock released it has cracked and eroded into these fantastic forms. You could spend hours enjoying all the fascinating angles and views.

(difficult trip out - "On August 3rd we began the 60-mile journey to the ocean. Rain, fog, and poor visibility made the trip a most uncomfortable one. When we reached the beach on August 9th we didn’t have a piece of dry clothing among us. The preceding six days had been too much for even waterproof articles. To add to our misery, a cache of food left on the beach was stolen, apparently by fishermen. We were reduced to a diet of wild peas for three days. On August 12th we were picked up by Merriman. Dr. Robert Sharp, geologist studying the Malaspina Glacier, had spotted us earlier that day while attempting to air drop supplies at his camp on the Malaspina Glacier.")

"Named in 1874 by . H. Dall, U.S. Coast and Geodetic Survey (USC&GS), for Captain James Cook, 1728-79, English navigator and explorer who was responsible for considerable exploration of the Alaska coast as far north as Icy Cape, near latitude 70." - edits.nationalmap.gov/apps/gaz-domestic/public/summary/13...

"In 1874 W. H. Dali and Marcus Baker of the U. S. Coast Survey named Mounts Cook and Vancouver from the sea, but somehow the names and elevations must have gotten scrambled, as they mapped Cook’s approximate elevation on Vancouver and Vancouver’s approximate elevation on Cook, and surely they had intended the higher mountain to bear Cook’s name, for he was the more famous of the two British navigators. At any rate, the names stuck where they first appeared on the maps and the elevations were soon applied to the right mountains. At the time of the Klondike gold rush the need was seen to determine the Alaska-Canada boundary more precisely, as the old Russian-British Treaty of 1825 had merely said for this section, "the chain of mountains which follow, at a very small distance, the winding of the coast.” The crests and interior of the Saint Elias Mountains were quite unknown around 1900 and "a very small distance” was taken to be within 10 marine leagues, so it was decided to connect prominent peaks no more than 34½ miles from the sea to form the boundary between the head of Portland Canal and the 141st meridian. Mount Vancouver was used as Boundary Peak 181, but the surveyors went in no further than the sea in this area, hence they used the south-southeast summit rather than the higher one hidden behind it."
