Guinevere Castle
Guinevere Castle is a 7,281-foot-elevation (2,219 meter) summit located in the Grand Canyon, in Coconino County of northern Arizona, US. It is situated one-half mile southeast of King Arthur Castle, one mile west of Excalibur, and 2.5 miles northeast of Evans Butte, within the Shinumo Amphitheater. Topographic relief is significant as it rises 5,000 feet (1,524 meters) above the Colorado River in 4.5 miles (7.2 km), and 2,600 feet above Gawain Abyss in one mile. According to the Köppen climate classification system, Guinevere 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. Guinevere Castle was named by cartographer Richard Tranter Evans (1881–1966), after Guinevere, queen and wife of King Arthur, in keeping with an Arthurian naming theme for other geographical features in the vicinity, e.g. ''King A ...

Dox Castle
Dox Castle is a 4,780-foot-elevation (1,460 meter) summit located in the Grand Canyon, in Coconino County of northern Arizona, US. It is situated four miles north-northeast of Havasupai Point, two miles northwest of Evans Butte, and 2.5 miles southwest of Holy Grail Temple, where it towers 2,500 feet (760 meters) above the Colorado River. Dox Castle was named by William Wallace Bass and George Wharton James for Virginia Dox (1851–1941), who was the first white woman to visit this part of the Grand Canyon in 1891. Holy Grail Temple was originally named ''Bass Tomb'' by Virginia Dox, for William Bass, Dox's guide into the canyon. Impressed by her, Bass named Dox Castle shorty after she left. This butte's name was officially adopted in 1908 by the U.S. Board on Geographic Names. According to the Köppen climate classification system, Dox Castle is located in a cold semi-arid climate zone, with precipitation runoff Runoff, run-off or RUNOFF may refer to: * RUN ...

Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora. Known for its dramatic canyons, whitewater rapids, and eleven U.S. National Parks, the Colorado River and its tributaries are a vital source of water for 40 million people. An extensive system of dams ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Kaibab Limestone
The Kaibab Limestone is a resistant cliff-forming, Permian geologic formation that crops out across the U.S. states of northern Arizona, southern Utah, east central Nevada and southeast California. It is also known as the Kaibab Formation in Arizona, Nevada, and Utah. The Kaibab Limestone forms the rim of the Grand Canyon. In the Big Maria Mountains, California, the Kaibab Limestone is highly metamorphosed and known as the Kaibab Marble. Nomenclature The Kaibab Limestone was named by Darton in 1910 for the Kaibab Plateau, which is on the north side of Grand Canyon in Coconino County, Arizona. In his definition of the Kaibab Limestone formation, no type locality was designated. He also designated the Kaibab Limestone as the upper formation of the Aubrey Group, a now-abandoned stratigraphic unit. In 1921, Bassler and Reeside revised Darton's work and defined the Harrisburg Member of the Kaibab Limestone.Bassler, H., and J. B. Reeside, Jr., 1921, ''Oil prospects in Washington C ...

Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of th ... [...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, ethnic cleansin ...

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] |

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legend Of King Arthur
King Arthur ( cy, Brenin Arthur, kw, Arthur Gernow, br, Roue Arzhur) is a Legend, legendary king of Great Britain, Britain, and a central figure in the medieval literary tradition known as the Matter of Britain. In the earliest traditions, Arthur appears as a leader of the post-Roman Celtic Britons, Britons in battles against Saxons, Saxon invaders of Britain in the late 5th and early 6th centuries. He appears in two early medieval historical sources, the ''Annales Cambriae'' and the ''Historia Brittonum'', but these date to 300 years after he is supposed to have lived, and most historians who study the period do not consider him a Historicity of King Arthur, historical figure.Tom Shippey, "So Much Smoke", ''review'' of , ''London Review of Books'', 40:24:23 (20 December 2018) His name also occurs in early Welsh language, Welsh poetic sources such as ''Y Gododdin''.

Guinevere
Guinevere ( ; cy, Gwenhwyfar ; br, Gwenivar, kw, Gwynnever), also often written in Modern English as Guenevere or Guenever, was, according to Arthurian legend, an early-medieval queen of Great Britain and the wife of King Arthur. First mentioned in popular literature in the early 12th century, nearly 700 years after the purported times of Arthur, Guinevere has since been portrayed as everything from a villainous and opportunistic traitor to a fatally flawed but noble and virtuous lady. Many records of the legend also feature the variably recounted story of her abduction and rescue as a major part of the tale. The earliest datable appearance of Guinevere is in Geoffrey of Monmouth's pseudo-historical British chronicle '' Historia Regum Britanniae'', in which she is seduced by Mordred during his ill-fated rebellion against Arthur. In a later medieval Arthurian romance tradition from France, a prominent story arc is the queen's tragic love affair with her husband's chief k ...

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 ...
