Pillar (landform)
A pillar is a landform, either of rock or earth, defined by the USGS as: "Vertical, standing, often spire-shaped, natural rock formation (chimney, monument, pinnacle, pohaku, rock tower)." Some examples of rock pillars are Chambers Pillar, Katskhi pillar, Pompeys Pillar, and Pillar Rock. The Oxford Dictionary of Geography defines ''earth pillar'' as: "An upstanding, free column of soil that has been sheltered from erosion by a natural cap of stone on the top. They are common where boulder-rich moraines have been subject to gully erosion, as in parts of the southern Tyrol." A Hoodoo is another type of earth pillar. Examples of earth pillars are Awa Sand Pillars and Đavolja Varoš Đavolja varoš ( sr-cyr, Ђавоља варош, lit. "Devil's Town") is a rock formation consisting of about 200 earth pyramids or "towers", located in southern Serbia on the Radan Mountain, in the municipality of Kuršumlija. Geology Đa ....

Landform
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Rock Pinnacle
A pinnacle, tower, spire, needle or natural tower (german: Felsnadel, ''Felsturm'' or ''Felszinne'') in geology is an individual column of rock, isolated from other rocks or groups of rocks, in the shape of a vertical shaft or spire. Examples are the summits of the Aiguille du Midi in the Mont Blanc massif in France, the almost 43-metre-high Barbarine on the south side of the Pfaffenstein hill near Königstein in Germany, or the Bischofsmütze, the Drei Zinnen and the Vajolet Towers in the Dolomites, which are rich in such towers. An area of limestone formations within Nambung National Park, near the town of Cervantes, Western Australia, is known as The Pinnacles.

Chambers Pillar
Chambers Pillar (Aboriginal name ''Idracowra'' or ''Etikaura'') is a sandstone formation some south of Alice Springs in the Northern Territory of Australia. Formation Erosion by wind and rain has left an isolated pillar of 350-million-year-old sandstone, rising above the surrounding plain. The rock formation and the surrounding area of 340 hectares, or , are officially named the ''Chambers Pillar Historical Reserve''. History John McDouall Stuart was the first European to see Chambers Pillar, reaching the site in April 1860, and naming it after James Chambers, one of his South Australian sponsors. The rock formations was once an important landmark for pioneers travelling from Adelaide to Alice Springs prior to the establishment of the railways in the 1920s. Several early explorers including Alfred Giles and John Ross, leaders of the second cross-continental expedition in 1870, have left their mark on the rockface. The initials of each are still visible as ''J Ross'' a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pompeys Pillar National Monument
Pompeys Pillar National Monument is a rock formation located in south central Montana, United States. Designated a National Monument on January 17, 2001, and managed by the U.S. Bureau of Land Management in conjunction with The Friends of Pompeys Pillar, it consists of only , making it one of the smallest National Monuments in the U.S. The community of Pompeys Pillar lies just east of the monument. History It was previously designated a National Historic Landmark on July 25, 1965. The new Pompeys Pillar Interpretive Center opened in 2006. Exhibits in the 5,700-square foot center relate the journey of Captain William Clark and his detachment, including Sacagawea and her son Pomp, down the Yellowstone River Valley in 1806. The pillar itself stands 150 feet (45 m) above the Yellowstone River and consists of sandstone from the late Cretaceous Hell Creek Formation, 75 – 66 million years ago. The base of the pillar is approximately . The pillar features an abundance of Nati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pillar Rock (California)
Morro Rock (Salinan: ''Le'samo; ''Chumash: ''Lisamu'''; Spanish: ''El Morro'') is a volcanic plug in Morro Bay, California, on the Pacific Coast at the entrance to Morro Bay harbor. A causeway connects it with the shore, making it a tied island. The rock is protected as the Morro Rock State Preserve. Geology The Morro Rock is one of 13 volcanic plugs (remnant necks of extinct volcanoes), lava domes, and sheetlike intrusions between Morro Bay on the north and Islay Hill on the south, all in San Luis Obispo County. It is composed mostly of dacite, an igneous, volcanic rock, and partially of petrified bird feces, which have compacted into the plug over the years. It is a groundmass of plagioclase, with amphibole (hornblende), biotite, pyroxene (augite), quartz, and glass; phenocrysts of plagioclase. Its silica dioxide (SiO2) content can range from 63 to 69 percent. The dacite volcanic plugs, lava domes, intrusive sheets, and felsitic rhyolite-dacite between Morro ...

Oxford English Dictionary
The ''Oxford English Dictionary'' (''OED'') is the first and foundational historical dictionary of the English language, published by Oxford University Press (OUP). It traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, as well as describing usage in its many variations throughout the world. Work began on the dictionary in 1857, but it was only in 1884 that it began to be published in unbound fascicles as work continued on the project, under the name of ''A New English Dictionary on Historical Principles; Founded Mainly on the Materials Collected by The Philological Society''. In 1895, the title ''The Oxford English Dictionary'' was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 bound volumes. In 1933, the title ''The Oxford English Dictionary'' fully replaced the former name in all occurrences in its reprinting as 12 volumes with a one-v ...

Hoodoo (geology)
A hoodoo (also called a tent rock, fairy chimney, or earth pyramid) is a tall, thin spire of rock formed by erosion. Hoodoos typically consist of relatively soft rock topped by harder, less easily eroded stone that protects each column from the elements. They generally form within sedimentary rock and volcanic rock formations. Hoodoos range in size from the height of an average human to heights exceeding a 10-story building. Hoodoo shapes are affected by the erosional patterns of alternating hard and softer rock layers. Minerals deposited within different rock types can cause hoodoos to have different colors throughout their height. Etymology In certain regions of western North America these rocky structures are called hoodoos. The name is derived from Hoodoo spirituality, in which certain natural forms are said to possess certain powers, but by the late 19th century, this spirituality became associated with bad luck. Prior to the English name for these geographic formations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
