Mont Mégantic
Mont Mégantic (; Abenaki: Namesokanjik) is a monadnock located in Québec, Canada, about north of the border between Québec and the U.S. states of Maine and New Hampshire. Mégantic is on the border of the regional county municipalities of Le Granit and Le Haut-Saint-François. Its summit is the highest point of the latter. Many geologists believe that Mont Mégantic is a member of the Monteregian Hills formed by the New England hotspot, as it has the same mechanism and depth of intrusion. Mont Mégantic stands within the watershed of the Saint Lawrence River, which drains into the Gulf of Saint Lawrence. The east side of Mégantic drains into Rivière Victoria, thence into Lac Mégantic, the Chaudière River, and the St. Lawrence. The rest of Mégantic drains into Rivière Au Saumon (Salmon River), thence into the Saint-François River, and the St. Lawrence. Observatoire du Mont Mégantic (OMM) is located on the mountain's summit, which is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intrusion
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California. Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained (phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks. Intrusions ...

Mont-Mégantic National Park
Mont-Mégantic National Park ''(Parc national du Mont-Mégantic)'' is a provincial park in Quebec, Canada. It is located near the municipality of Notre-Dame-des-Bois in the Estrie region. The park was created in 1994 and is adjacent to the Samuel-Brisson Ecological Reserve which is located northeast of it. Mont Mégantic is the approximate geographic centre of the park. Located at its peak is the Mont Mégantic Observatory, which is the most important astronomical observatory in eastern Canada. Part of the park is also recognized as important area for bird conservation. The park is managed by the Quebec government through the Société des établissements de plein air du Québec (SÉPAQ). Special features of the park The park terrain is characteristic of the frontier mountains in the Appalachia region, although the bulk of it is in fact the most easterly of the Montérégie. Four peaks are accessible by hiking trails including the Pic de l'Aurore ( ), Mont Victoria ( ), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mont Mégantic Observatory
The Mont Mégantic Observatory (french: Observatoire du Mont-Mégantic; OMM) is an astronomical observatory owned and operated jointly by the Université de Montréal (UdeM), and the Université Laval (ULaval). Founded in 1978, the observatory houses the second largest telescope in Eastern Canada after David Dunlap Observatory near Toronto. It is situated at the summit of Mont Mégantic, the highest point of Eastern Canada accessible by car. OMM is about east of Sherbrooke and east of Montreal. The asteroid 4843 Mégantic is named for the observatory. Telescope The Ritchey-Chrétien telescope is equipped with a complement of modern instruments. Imaging, spectroscopy, and polarimetry are routinely conducted at both visible and infrared wavelengths. Light pollution Efforts to control local light pollution, about one-quarter of which is due to the nearby city of Sherbrooke, have led to the establishment of the world's first International Dark-Sky Association (IDA) Da ...

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
20040720 OMM
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other han ...

Saint-François River
The Saint-François River is a right tributary of the St. Lawrence River in Quebec, Canada. Its source is Lake Saint-François in Chaudière-Appalaches, southeast of Thetford Mines. It flows southwest towards Sherbrooke, where it changes course northwest towards Drummondville, and finally empties into the Saint Lawrence River near Pierreville. Its total length is 135 miles. Etymology The river is named after Saint Francis Xavier (1506–1552) by the Jesuits, who explored the region under the French regime, and after François de Lauzon.François de Lauzon (1635-1647 or 1648), son of Jean de Lauzon Geography Its course is also unusual, as it flows from northeast to southwest to branch off, halfway through, and continue its course from southeast to northwest. The Saint-François River has its origins in the lake Saint-François and heads southwest towards Sherbrooke. Along the way, it crosses the lakes Lake Aylmer and Lake Louise as well as many municipalities. In Sherb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaudière River
The Chaudière River (French for "Cauldron" or "Boiler"; Abenaki: Kik8ntekw) is a river with its source near the Town of Lac-Mégantic, in southeast Quebec, Canada. From its source Lake Mégantic in the Estrie region, it runs northwards to flow into the St. Lawrence River opposite Quebec City. Geography The river's drainage area is , initially in the Appalachian Mountains, then in the low-lands of the St. Lawrence, and include 236 lakes covering and approximately 180,000 inhabitants. Its annual medium flow at the station of Saint-Lambert-de-Lauzon is , varying from (low water) to (spring high water), with historical maximum of . Its principal tributaries are: *Rivière du Loup (not to be confused with Rivière du Loup in the Bas-Saint-Laurent), also known as the Rivière Linière *Famine River *Beaurivage River * Bras Saint-Victor The river's basin has nearly 50 percent of the faunal richness of Quebec, namely 330 out of 653 vertebrate species known in the province ca ...

Lac Mégantic
Lac is the resinous secretion of a number of species of lac insects, of which the most commonly cultivated is ''Kerria lacca''. Cultivation begins when a farmer gets a stick that contains eggs ready to hatch and ties it to the tree to be infested. Thousands of lac insects colonize the branches of the host trees and secrete the resinous pigment. The coated branches of the host trees are cut and harvested as sticklac. The harvested sticklac is crushed and sieved to remove impurities. The sieved material is then repeatedly washed to remove insect parts and other material. The resulting product is known as seedlac. The prefix ''seed'' refers to its pellet shape. Seedlac, which still contains 3–5% impurity, is processed into shellac by heat treatment or solvent extraction. The leading producer of lac is Jharkhand, followed by the Chhattisgarh, West Bengal, and Maharashtra states of India. Lac production is also found in Bangladesh, Myanmar, Thailand, Laos, Vietnam, parts of C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
