Elaine Castle
Elaine Castle is a 7,431-foot-elevation (2,265 meter) summit located in the Grand Canyon, in Coconino County of northern Arizona, US. It is situated three miles north-northwest of King Arthur Castle near the head of Shinumo Creek, and immediately southwest of Lancelot Point. Topographic relief is significant as it rises above Merlin Abyss in one mile. According to the Köppen climate classification system, Elaine Castle is located in a cold semi-arid climate zone. History Clarence Dutton started the tradition of naming geographical features in the Grand Canyon after mythological deities and heroic figures. Elaine Castle was named by cartographer Richard Tranter Evans (1881–1966), after Elaine of Astolat, from the Legend of King Arthur, in keeping with an Arthurian naming theme for other geographical features in the vicinity, e.g. ''King Arthur Castle'', '' Guinevere Castle'', ''Excalibur'', ''Gawain Abyss'', ''Holy Grail Temple'', ''Bedivere Point'', ''Lancelot Poin ...

Kaibab Plateau
The Kaibab Plateau is a plateau almost entirely in Coconino County, Arizona (but extending slightly north into Kane County, Utah) in the Southwestern United States. The high plain is also known as the Buckskin Mountain, Buckskin Plateau, and Kaibab Mountain. Description The plateau, part of the larger Colorado Plateau, is bordered on the south by the Grand Canyon and reaches an elevation of . The plateau is divided between Kaibab National Forest and the "North Rim" portion of Grand Canyon National Park. Tributary canyons of the Colorado River form the plateau's eastern and western boundaries, and tiers of uplifted cliffs define the northern edges of the landform. Winter snowfall is often heavy (sometimes exceeding ), and this creates opportunities for backcountry Nordic skiing and snow camping. This broad feature is heavily forested with aspen, spruce- fir, ponderosa pine, and pinyon-juniper woodland, and stands in sharp contrast to the arid lowlands encircling it. The ...

Cartography
Cartography (; from grc, χάρτης , "papyrus, sheet of paper, map"; and , "write") is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: * Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. * Represent the terrain of the mapped object on flat media. This is the concern of map projections. * Eliminate characteristics of the mapped object that are not relevant to the map's purpose. This is the concern of generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements of the ...

Hermit Formation
The Permian Hermit Formation, also known as the Hermit Shale, is a nonresistant unit that is composed of slope-forming reddish brown siltstone, mudstone, and very fine-grained sandstone. Within the Grand Canyon region, the upper part of the Hermit Formation contains red and white, massive, calcareous sandstone and siltstone beds that exhibit low-angle cross-bedding. Beds of dark red crumbly siltstone fill shallow paleochannels that are quite common in this formation. The siltstone beds often contain poorly preserved plant fossils. The Hermit Formation varies in thickness from about in the eastern part of the Grand Canyon region to about in the region of Toroweap and Shivwits Plateaus. In the Sedona, Arizona area, it averages in thickness. The upper contact of the Hermit Formation is typically sharp and lacks gradation of any kind. The lower contact is a disconformity characterized by a significant amount of erosional relief, including paleovalleys as much as deep. See ...

Coconino Sandstone
Coconino Sandstone is a geologic formation named after its exposure in Coconino County, Arizona. This formation spreads across the Colorado Plateau province of the United States, including northern Arizona, northwest Colorado, Nevada, and Utah. This rock formation is particularly prominent in the Grand Canyon, where it is visible as a prominent white cliff-forming layer. The thickness of the formation varies due to regional structural features; in the Grand Canyon area it is only thick in the west, thickens to over in the middle and then thins to in the east. Either the Kaibab Limestone or Toroweap Formation overlies the Coconino Sandstone. The Coconino Sandstone is typically buff to white in color. It consists primarily of fine well-sorted quartz grains, with minor amounts of potassium feldspar grains deposited by eolian processes (wind-deposited) approximately 275 million years ago. Several structural features such as ripple marks, sand dune deposits, rain patches, slump ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caprock
Caprock or cap rock is a more resistant rock type overlying a less resistant rock type,Kearey, Philip (2001). ''Dictionary of Geology'', 2nd ed., Penguin Reference, London, New York, etc., p. 41.. . analogous to an upper crust on a cake that is harder than the underlying layer. Description The Niagara Escarpment, over which Niagara Falls flows, is an example of a scarp or escarpment. At Niagara Falls, the caprock is the riverbed above the falls, and is what prevents the river from eroding the face of the falls very quickly. In the photo, the dark thin layer in the foreground where water is not yet running, is the caprock. The Niagara caprock is made of dolomitic limestone. Other common types of caprock are sandstone and mafic rock. In processes such as scarp retreat, the caprock controls the rate of erosion of the scarp. As the softer rock is cut away, periodically the caprock shears off. Caprock is also found in salt domes and on the top of mesa formations. Petroleum In the ...

Toroweap Formation
The Middle Permian Toroweap Formation is a thin, darker geologic unit, between the brighter colored units of the Kaibab Limestone above, and Coconino Sandstone below. It is a prominent unit in Grand Canyon, Arizona, USA, found through sections of the South Rim, Grand Canyon, and the North Rim, of the Kaibab Plateau; also the Kaibab's southeast extension to Cape Royal, the Walhalla Plateau. The Colorado River of the Grand Canyon makes its excursion from due-south to due-west around the Walhalla Plateau, as it enters the east end of the Grand Canyon's interior, Granite Gorge. The formation is also found in southeast Utah. The Toroweap Formation is a darker unit of gypsum and shale; also sandstone. In photos the '' cliff-forming'' Kaibab and Coconino units, show the more erodable Toroweap Formation '' slope-forming'' accumulations upon the underlying Coconino Sandstone; likewise below the Coconino, the softer Hermit Formation is shown forming slopes, above the slope forming 're ...

Butte
__NOTOC__ In geomorphology, a butte () is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands. The word ''butte'' comes from a French word meaning knoll (but of any size); its use is prevalent in the Western United States, including the southwest where ''mesa'' (Spanish for "table") is used for the larger landform. Due to their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas. To differentiate the two landforms, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height. Formation Buttes form by weathering and erosion when hard caprock overlies a layer of less resistant rock that is eventually worn away. The harder rock on top of the butte resists erosion. The caprock provides protection for the less resistant rock below from wind abrasion which leaves it stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harvey Butchart
John Harvey Butchart (May 10, 1907 – May 29, 2002) was a mathematics professor who was well known for his hiking exploits in and around the Grand Canyon in Arizona, United States. Beginning in 1945, Butchart explored the Grand Canyon's backcountry on foot. He wrote extensively about his adventures and influenced generations of canyoneers. Sparse human communities have lived, worked, and traveled in the harsh and beautiful Canyon terrain at least since the Ancestral Puebloans. Native Americans occupied parts of the canyon in the mid 1800s when American explorers first arrived, followed over time by prospectors, miners, researchers, and the outdoor tourists who now dominate the community. Most of the millions of visitors to Grand Canyon National Park remain in the developed South and North Rim areas. A smaller number hike into the Canyon along a few well-maintained trails. A very small number venture beyond, into the true wilderness of the Park. Harvey Butchart led the way, usi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Americans In The United States
Native Americans, also known as American Indians, First Americans, Indigenous Americans, and other terms, are the Indigenous peoples of the mainland United States ( Indigenous peoples of Hawaii, Alaska and territories of the United States are generally known by other terms). There are 574 federally recognized tribes living within the US, about half of which are associated with Indian reservations. As defined by the United States Census, "Native Americans" are Indigenous tribes that are originally from the contiguous United States, along with Alaska Natives. Indigenous peoples of the United States who are not listed as American Indian or Alaska Native include Native Hawaiians, Samoan Americans, and the Chamorro people. The US Census groups these peoples as " Native Hawaiian and other Pacific Islanders". European colonization of the Americas, which began in 1492, resulted in a precipitous decline in Native American population because of new diseases, wars, ethni ...

Arthurian Legend
The Matter of Britain is the body of medieval literature and legendary material associated with Great Britain and Brittany and the legendary kings and heroes associated with it, particularly King Arthur. It was one of the three great Western story cycles recalled repeatedly in medieval literature, together with the Matter of France, which concerned the legends of Charlemagne, and the Matter of Rome, which included material derived from or inspired by classical mythology. History The three "Matters" were first described in the 12th century by French poet Jean Bodel, whose epic ' ("Song of the Saxons") contains the line: The name distinguishes and relates the Matter of Britain from the mythological themes taken from classical antiquity, the "Matter of Rome", and the tales of the Paladins of Charlemagne and their wars with the Moors and Saracens, which constituted the " Matter of France". King Arthur is the chief subject of the Matter of Britain, along with stories relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
