Mount Katahdin
Mount Katahdin ( ) is the highest mountain in the U.S. state of Maine at . Named Katahdin, which means "Great Mountain", by the Penobscot Native Americans, it is within Northeast Piscataquis, Piscataquis County, and is the centerpiece of Baxter State Park. It is a steep, tall massif formed from a granite intrusion weathered to the surface. The flora and fauna on the mountain are typical of those found in northern New England, with the summit hosting fragile and endangered alpine tundra. Katahdin has been known to the Native Americans in the region for thousands of years and was known to Europeans at least since 1689. It has inspired hikes, climbs, journal narratives, paintings, and a piano sonata. The area around the peak was protected by Governor Percival Baxter starting in the 1930s, who spent much of his personal fortune purchasing the mountain and surrounding lands after being unable to convince the state legislature of the wisdom of protecting it. Katahdin is the no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Massif
A massif () is a principal mountain mass, such as a compact portion of a mountain range, containing one or more summits (e.g. France's Massif Central). In mountaineering literature, ''massif'' is frequently used to denote the main mass of an individual mountain. As a purely scientific term in geology, however, a "massif" is separately and more specifically defined as a section of a planet's crust (geology), crust that is demarcated by geologic fault, faults or lithospheric flexure, flexures. In the plate tectonics, movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. A massif is a smaller structural unit than a tectonic plate and is considered the fourth-largest driving force in geomorphology. The word "massif" originates from French (in which the word also means "massive"), where it is used to refer to a large mountain mass or compact group of connected mountains forming an independent portion of a range.

Island Arc
Island arcs are long archipelago, chains of active volcanoes with intense earthquake, seismic activity found along convergent boundary, convergent plate tectonics, tectonic plate boundaries. Most island arcs originate on oceanic crust and have resulted from the descent of the lithosphere into the Earth's mantle, mantle along the subduction zone. They are the principal way by which continental growth is achieved. Island arcs can either be active or inactive based on their seismicity and presence of volcanoes. Active arcs are ridges of recent volcanoes with an associated deep seismic zone. They also possess a distinct curved form, a chain of active or recently extinct volcanoes, a oceanic trench, deep-sea trench, and a large negative Bouguer anomaly on the convex side of the volcanic arc. The small positive gravity anomaly associated with volcanic arcs has been interpreted by many authors as due to the presence of dense volcanic rocks beneath the arc. Inactive arcs are a chain of ...

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a Federal government of the United States, federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geography, geographic names throughout the federal government of the United States. History Following the American Civil War, more and more American pioneer, American settlers began moving westward, prompting the Federal government of the United States, U.S. federal government to pursue some sort of consistency for referencing landmarks on maps and in official documents. As such, on January 8, 1890, Thomas Corwin Mendenhall, superintendent of the United States Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography."

Presidential Range
The Presidential Range is a mountain range located in the White Mountains of the U.S. state of New Hampshire. It contains the highest peaks of the Whites, the most notable of which are named for American presidents, followed by prominent public figures of the 18th and 19th centuries. The Presidential Range is notorious for having some of the worst weather on Earth, mainly because of the unpredictability of high wind speeds and whiteout conditions on the higher summits. Because of the poor weather conditions, the Presidential Range is often used for mountaineering training for those who go on to climb some of the world's highest mountains, including K2 and Everest. Mount Washington, long home of the highest winds recorded on the surface of the Earth at , is the tallest at , followed by neighboring peaks Mount Adams at and Mount Jefferson at . The range is almost entirely in Coos County. Notable summits The highest mountains in the Presidential Range are named principa ...

Inselberg
An inselberg or monadnock ( ) is an isolated rock hill, knob, ridge, or small mountain that rises abruptly from a gently sloping or virtually level surrounding plain. In Southern Africa, a similar formation of granite is known as a koppie, an Afrikaans word ("little head") from the Dutch diminutive word ''kopje''. If the inselberg is dome-shaped and formed from granite or gneiss, it can also be called a bornhardt, though not all bornhardts are inselbergs. An inselberg results when a body of rock resistant to erosion, such as granite, occurring within a body of softer rocks, is exposed by differential erosion and lowering of the surrounding landscape. Etymology Inselberg The word ''inselberg'' is a loan word from German, and means "island mountain". The term was coined in 1900 by geologist Wilhelm Bornhardt (1864–1946) to describe the abundance of such features found in eastern Africa. At that time, the term applied only to arid landscape features. However, it has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Percival P
Perceval (, also written Percival, Parzival, Parsifal), alternatively called Peredur (), is a figure in the legend of King Arthur, often appearing as one of the Knights of the Round Table. First mentioned by the French author Chrétien de Troyes in the tale ''Perceval, the Story of the Grail'', he is best known for being the original hero in the quest for the Grail before being replaced in later literature by Galahad. Etymology and origin The earliest reference to Perceval is found in Chrétien de Troyes's first Arthurian romance ''Erec et Enide'', where, as "Percevaus li Galois" (Percevaus of Wales), he appears in a list of Arthur's knights. In another of Chrétien's romances, '' Cligés'', Perceval is a "renowned vassal" who is defeated by the knight Cligés in a tournament. He then becomes the eponymous protagonist of Chrétien's final romance, ''Perceval, the Story of the Grail''. In the Welsh romance '' Peredur son of Efrawg'', the corresponding figure goes by the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
