Buildings on St. Olaf Street in Downtown Baltic, South Dakota. The building on the left is the Schroyer Block, which now houses the American Legion Post #175. Dr. Charles Tilden Schroyer was born in 1876 in Adamsville, Ohio and came to Baltic after getting his medical degree from the Ohio Medical College. He built this quartzite building in 1902 to house his clinic. Schroyer later moved to Sioux Falls, South Dakota and practiced there. He died in 1948.

Cheverton-IOOF Block, 115 West Main Street, Pipestone, Minnesota. William Frost constructed the eastern portion of this two-story quartzite building circa 1889. A few years later, in 1896, Frost sold the building for $6,000 to the International Order of Odd Fellows (I.O.O.F.) which had been renting the second floor. Upon purchasing the building, the Cheverton Block stone atop the building was replaced with the I.O.O.F. initials, which still grace the building today. The I.O.O.F. purchased the adjoining lot to the west in 1910 and constructed a nearly matching building, except for the segmented arches over the second floor windows. The original east arches were constructed of sandstone, while the newer west ones are gray pink Sioux quartzite. Like many commercial buildings throughout the Midwest, the building housed two stores until the Ben Franklin store moved in and combined them. In the late 19th century, the building also accommodated an opera house on the second floor. I.O.O.F. remained in the second floor until the early 1970s. The first floor facade has been altered several times, removing recognizable traces of its original character. The second floor, however, still retains much of its original historic fabric, including oak trim and the original pressed tin ceiling. The ground floor is now the home of Sojo's Sportswear. The Pipestone Odd Fellows disbanded in 2009 due to falling membership.

Big Rock (glacial erratic). Big Rock (also known as Okotoks Erratic) is a glacial erratic situated between the towns of Okotoks and Black Diamond, Alberta, Canada The 16,500 ton quartzite boulder is one of the world's largest known glacial erratics. This huge erratic can be seen for miles away setting out on the rolling prairie and ranchland, long before you get there. The Foothills Erratics Train extends along the eastern flanks of the Rocky Mountains of Alberta and northern Montana to the International Border.
Reigned 2029-1982 BCE.

My main reason for visiting this area, which included Kruger National Park, was to see the Three Rondavels on the Panorama Route. We were lucky to have a lovely afternoon view of it as the next day all the mountains were covered in cloud.

Errigal (An Earagail) is the most southern, steepest and highest of the mountain chain, called the "Seven Sisters". The Seven Sisters includes Muckish, Crocknalaragagh, Aghla Beg, Ardloughnabrackbaddy, Aghla More, Mackoght and Errigal. The nearest peak is Mackoght Irish and meaning "son of the mountain breast", is also known as Little Errigal or Wee Errigal.
Errigal is known for the pinkish glow of its quartzite in the setting sun.Another noted quality is the ever changing shape of the mountain depending on what direction you view it from.
The legend of Errigal states it has been named by the Fir Bolg who, originating in Greece, came to worship Errigal as they had Mount Olympus. The name comes from the Latin orare (to pray) and the Greek ekklesia (church). Scholars consider it one of the oldest placenames in Ireland. A more prosaic origin for the name is from the Old Irish airecal, meaning "oratory". There is no remains of an oratory on the mountain, so it may refer to the mountain as a whole as a place of prayer.
Ontario, Canada
Considered one of Ontario Parks' crown jewels, this majestic, mountainous wilderness of sapphire lakes and jack pine ridges so captivated artists - including The Group of Seven's A.Y. Jackson - that they persuaded the Ontario government to make it a park. Once higher than the Rocky Mountains, La Cloche's white quartzite cliffs gleam like snowy peaks from afar. Where paddlers, hikers, skiers and snowshoers now journey through in this craggy, imposing landscape, there is evidence that others passed thousands of years before.
A first impression of Killarney reveals impressive white quartzite hills of the La Cloche range , and crystal clear lakes nestled between them.
Phenomenal scenery , defined by the presence of some very old rocks, distinguishes this area from other parts of Ontario. White quartzite ,pink granite and reddish gheiss are the three main rock types colouring Killarney's landscapes.

One of a pair, this colossal figure with features of a young man may have stood in Tutankhamun's mortuary temple. After his early death, Ay appropriated the statue and carved his name on the front belt. Horemheb, in turn, took it over for his use and reinscribed the belt with his name. The large amount of surviving paint provides a hint of its original vivid colors.
High up in the Shropshire Hills lie these quartzite rocky tors called the Stiperstones. They were formed around 480 million years ago. During the last ice age the hill itself wasn't glasiated, though the surrounding valleys were, so the tors were subjected to intense freezing and thawing which shattered the quartzite into these amazing shapes, some of the tors have a mass of scree at there base.

Errigal is a 751-metre mountain near Gweedore in County Donegal, Ireland. It is the tallest peak of the Derryveagh Mountains, the tallest peak in County Donegal, and the 76th tallest peak in Ireland. Errigal is also the most southern, steepest and highest of the mountain chain, called the "Seven Sisters" by locals. The Seven Sisters includes Muckish, Crocknalaragagh, Aghla Beg, Ardloughnabrackbaddy, Aghla More, Mackoght and Errigal. The nearest peak is Mackoght, which is also known as Little Errigal or Wee Errigal.
Errigal is well known for the pinkish glow of its quartzite in the setting sun. Another noted quality is the ever-changing shape of the mountain depending on what direction you view it from. Errigal was voted 'Ireland's Most Iconic Mountain' by Walking & Hiking Ireland in 2009.
Quartzite in the Precambrian of South Dakota, USA.
Extensive outcrops of pinkish, Paleoproterozoic-aged quartzites are present at Falls Park along the Big Sioux River in the city of Sioux Falls, South Dakota. The quartzites here have nicely water-worn, sculpted surfaces. These rocks are part of the Sioux Quartzite, which consists of 1.65 to 1.70 billion year old metamorphosed sandstones. Despite the metamorphism, original sedimentary features such as horizontal stratification, cross-bedding, and ripple marks are still preserved.
The Sioux Quartzite is an erosion-resistant unit in America’s midcontinent. It has formed a long-lived paleotopographic high since Precambrian times - the Sioux tectonic core. This high is part of a northeast-to-southwest trending series of paleotopographic highs & depressions known as the Transcontinental Arch, which extends from Arizona to Minnesota (see Carlson, 1999).
Quarries of Sioux Quartzite occur in southeastern South Dakota and southwestern Minnesota. The rocks are used as building stone, road gravel, sidewalk and paving gravel, and erosion control material.
Stratigraphy: Sioux Quartzite, upper Paleoproterozoic, 1.65-1.70 Ga
Locality: Falls Park, near Sioux Falls along the Big Sioux River in the town of Sioux Falls, southeastern South Dakota, USA

Quartz-pebble metaconglomerate from the Precambrian of Australia. (Cranbrook Institute of Science collection, Bloomfield Hills, Michigan, USA)
Very old rocks are common on the Moon and in the Asteroid Belt. Very old rocks are scarce on Earth - this is the result of erosion by running water and plate tectonic recycling and deformation. The oldest reported Earth rocks are all Canadian - the Acasta Gneiss (Eoarchean, 4.03 Ga), rocks in the Nuvvuagittuq Greenstone Belt (Eoarchean, 4.28 Ga), and subsurface Baffin Island rocks (Eoarchean, 4.45 to 4.55 Ga). The latter rocks are the ~same age as Planet Earth (4.55 Ga).
The rock shown above is a quartz-pebble metaconglomerate from the famous Jack Hills Quartzite (Jack Hills Formation). Microscopic detrital grains of the mineral zircon (ZrSiO4 - zirconium silicate) extracted from Jack Hills Quartzite rock samples are the oldest directly observable Earth materials. Jack Hills detrital zircons range in age from 3.05 Ga to 4.404 Ga. The latter date is early Eoarchean and very close to the age of the Earth. Many refer to this early time interval as "Hadean", but that term lacks a fixed definition and is rejected here.
The depositional age of Jack Hills Quartzite sediments is not well constrained. They were deposited after the youngest known detrital zircons (3.05 Ga) and before low-grade metamorphism of the rocks (2.655 Ga, based on dating of metamorphic monazite crystals).
Stratigraphy: Jack Hills Quartzite, Neoarchean to mid-Mesoarchean, ~2.65 to ~3.05 Ga

The rock ledges exposed at Two Lights State Park represent the current stage of a very long and dynamic geologic history. The rock that makes up the ledges is classified as metamorphic rock, which means that at one time it was affected by heat and pressure inside the earth which has significantly changed its form. Before metamorphism it was sedimentary rock, which had formed originally by hardening of deep-sea sediment (sand and mud) into rock.
420 million years ago, Silurian Period: Sediment accumulated in a deep ocean basin. This basin lay between the edge of North America to the west, which at the time ran approximately from Flagstaff Lake to northern Moosehead Lake, and an ancient small continent to the east, the microcontinent called Avalon.
The layers of sediment that accumulated in that Silurian ocean are preserved in the rocks at Two Lights as light gray, massive quartzite and dark gray phyllite layers. The quartzite layers were originally sand or silt beds, and the phyllite layers were originally clay or mud beds. As the layers accumulated one on the other, some were deposited individually with sharp boundaries between them, and others were deposited as mixed masses in graded beds that change gradually from the bottom to the top of the layer.
All the rocks at Two Lights State Park belong to a single geologic formation. Geologists in the early 1900's referred to it as the Cape Elizabeth Formation, but geologists now think that these rocks are part of the Kittery Formation , which is found along the southern Maine coast and into New Hampshire.

Devil's Lake State Park, Wisconsin, USA. The bluffs bordering Devil's Lake State Park create the illusion of a lake in a mountainous area because of the cliffs and large rocks on the slopes below them. The Lake lies in the Baraboo Range which scientists believe was formed 1.6 million years ago, making the exposed rocks one of the most ancient rock outcrops in North America.
Made of quartzite, a hard metaphoric rock, the cliffs are fractured by freeze-thaw cycles to form the large rocks on the slopes below. Mixed conifer-deciduous forests grow on the soils of the slopes. Beneath the West Bluff, the Tumble Rocks Trail lies at the juncture of the rocks and forest with the lake.

This grand Italianate villa, perched atop South Mountain, looks like a worthy subject for my series on fieldstone structures. But the Center's own website description states that the bouldery, somewhat coursed, somewhat rubble-set rock exterior was quarried, not collected from loose surface rock.
And the source quarry was located on a "nearby ridge." In fact, the stone is the Antietam Quartzite, of Cambrian age. From the US Geological Survey description of the Antietam Formation, I gather it's a metaquartzite (originally sandstone that was subsequently metamorphosed) rather than an orthoquartzite (unaltered sandstone cemented with silica).
However, the metamorphism was not intense enough to obliterate the Antietam's characteristic trace fossils, marine-organism sediment boring tubes of the ichnogenus Skolithos. The rock is variously described as white, light gray, and weathering to a buff tone. The material on display seems to bear all that out.
If my Pennsylvania bedrock map is not deceiving me, the Antietam Formation outcrops in this neck of the woods on a ridge to the north of this site. It's not surprising that it forms a topographic high; quartzite is tough stuff and resists erosion better than many other types do.
In my travels in this state and Maryland, I have absolutely fallen in love with South Mountain, which despite its name is the northernmost portion of the scenic and historic Blue Ridge Province that stretches down all the way to Georgia. The effect South Mountain had on troop movements and dispositions during the American Civil War, especially in the battles of Antietam and Gettysburg, was significant, to say the least. And its geology is so thoroughly fascinating.
And here at Kings Gap, one of its most interesting rock units is on display in a striking and publicly accessible architectural setting.

Quartzite is a common, crystalline-textured, intermediate- to high-grade metamorphic rock. It forms by metamorphism of quartzose sandstones or siltstones. Quartzite can be entirely composed of interlocking quartz crystals, or the original sand grains may still be visible. This rock is hard (H = 7), will not bubble in acid (unlike marble), and can be almost any color.
The term “quartzite” has been used in geology to refer to crystalline, quartzose metamorphic rocks and to hard, well-cemented quartzose sandstones that have not been subjected to metamorphism. It is difficult to not call hard, well-cemented sandstones “quartzite” - for example, the Clinch Quartzite in the Appalachian Mountains and the Eureka Quartzite of the Great Basin in western USA, but the Clinch and Eureka aren’t metamorphic rocks. The term "metaquartzite" has been used by some geologists to refer to crystalline-textured, quartzose rocks that have been metamorphosed. This implies that “quartzite” be restricted to well-cemented, non-metamorphosed sandstones. I don’t often see the term metaquartzite in the geologic literature.
The whitish quartzites seen here (interpreted as part of a metavolcanic unit) are Piedmont metamorphic basement rocks in Virginia. They are exposed in the footwall almost adjacent to a half-graben's eastern boundary fault, a normal fault (= obscured by vegetation at this locality). The hanging wall (a little north of this spot) consists of siliciclastic sedimentary rocks representing Triassic rift basin fill. The half-graben is the Danville Basin (Dan River Basin).

The World of Stonehenge
(February to July 2022)
Towering above the Wiltshire countryside, Stonehenge is perhaps the world's most awe-inspiring ancient stone circle.
Shrouded in layers of speculation and folklore, this iconic British monument has spurred myths and legends that persist today. In this special exhibition, the British Museum revealed the secrets of Stonehenge, shining a light on its purpose, cultural power and the people who created it.
Following the story of Britain and Europe from 4000 to 1000 BC, visitors learned about the restless and highly connected age of Stonehenge – a period of immense transformation and radical ideas that changed society forever.
The human story behind the stones revealed itself through a variety of fascinating objects. Among these were stone axes from the North Italian Alps, stunning gold jewellery and astonishing examples of early metalwork including the Nebra Sky Disc – the world's oldest surviving map of the stars. A remarkably preserved 4,000-year-old timber circle dubbed Seahenge also took centre stage in the show, on loan for the very first time. All these objects offered important clues about the beliefs, rituals, and complex worldview of Neolithic people, helping to build a vivid sense of life for Europe's earliest ancestors.
Informed by ground-breaking recent archaeological and scientific discoveries, this landmark exhibition offered new insight on one of the world's great wonders, bringing the true story of Stonehenge into sharper focus than ever before.

Quartzite sandstone statue of Seti II, created in Egypt about 1200 to 1194 BC. Found in the Temple of Mut at Karnak, Thebes.
Seti is shown offering a shrine to the god Amun. The shrine itself is decorated with the ram's head, symbol of Amun. On Seti's brow is the uraeus, or rearing cobra -- which protects him. Between his legs is a bull's tail, a symbol of strength. The papyrus and lotus images on his throne symbolized Upper and Lower Egypt.
