Tunjuelo River
The Tunjuelo or Tunjuelito River is a river on the Bogotá savanna and a left tributary of the Bogotá River. The river, with a length of originates in the Sumapaz Páramo and flows northward through the Usme Synclinal to enter the Colombian capital Bogotá. There, the river is mostly canalised flowing westward into the Bogotá River. It is one of the three main rivers of the city, together with the Fucha River, Fucha and Juan Amarillo Rivers. Etymology The names Tunjuelo and Tunjuelito ("little Tunjuelo") are derived from the Cerro de los Tunjos, also Los Tunjos Lake, named after the ''tunjos'', the Muisca religion, religious votive figurines of the indigenous language of the Muisca people, Muisca, who inhabited the Bogotá savanna before the Spanish conquest of the Muisca, Spanish conquest.Osorio Osorio, 2007, p.29 Description The Tunjuelo River has a total length of and originates in the Sumapaz Páramo, in the southern part of Bogotá.Osorio Osorio, 2007, p.12 It flows t ...

Chibcha Language
Chibcha, Mosca, Muisca, Muysca (*/ˈmɨska/), or Muysca de Bogotá, was a language spoken by the Muisca people of the Muisca Confederation, one of the many Indigenous peoples in Colombia, indigenous List of pre-Columbian cultures, cultures of the Americas. The Muisca inhabited the Altiplano Cundiboyacense of what today is the country of Colombia. The name of the language ''Muysc Cubun'' in its own language means "language of the people", from ''muysca'' ("people") and ''cubun'' ("language" or "word"). Despite the disappearance of the language in the 17th century (approximately), several language revitalization processes are underway within the current Muisca communities. The Muisca people remain ethnically distinct and their communities are recognized by the Colombian state. Important List of Muisca scholars, scholars who have contributed to the knowledge of the Chibcha language include Juan de Castellanos, Bernardo de Lugo, José Domingo Duquesne and Ezequiel Uricoechea. His ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ...

Conglomerate (geology)
Conglomerate () is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts. A conglomerate typically contains a matrix of finer-grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form by the consolidation and lithification of gravel. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks. In terms of origin and depositional mechanisms, they are closely related to sandstones and exhibit many of the same types of sedimentary structures, e.g., tabular and trough cross-bedding and graded bedding.Boggs, S. (2006) ''Principles of Sedimentology and Stratigraphy.'', 2nd ed. Prentice Hall, New York. 662 pp. Friedman, G.M. (2003) ''Classification of sediments and sedimentary rocks.'' In G ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Type Locality (geology)
Type locality, also called type area, is the locality where a particular rock type, stratigraphic unit or mineral species is first identified. If the stratigraphic unit in a locality is layered, it is called a stratotype, whereas the standard of reference for unlayered rocks is the type locality. The term is similar to the term type site in archaeology or the term type specimen in biology. Examples of geological type localities Rocks and minerals * Aragonite: Molina de Aragón, Guadalajara, Spain * Autunite: Autun, France * Benmoreite: Ben More (Mull), Scotland * Blairmorite: Blairmore, Alberta, Canada * Boninite: Bonin Islands, Japan * Comendite: Comende, San Pietro Island, Sardinia * Cummingtonite: Cummington, Massachusetts * Dunite: Dun Mountain, New Zealand. * Essexite: Essex County, Massachusetts, US * Fayalite: Horta, Fayal Island, Azores, Portugal * Harzburgite: Bad Harzburg, Germany * Icelandite: Thingmuli (Þingmúli), Iceland * Ijolite: Iivaara, Kuusamo, Finl ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ...

Spanish Conquest Of The Muisca
The Spanish conquest of the Muisca took place from 1537 to 1540. The Muisca were the inhabitants of the central Andean highlands of Colombia before the arrival of the Spanish conquistadors. They were organised in a loose confederation of different rulers; the '' psihipqua'' of Muyquytá, with his headquarters in Funza, the '' hoa'' of Hunza, the ''iraca'' of the sacred City of the Sun Sugamuxi, the Tundama of Tundama, and several other independent ''caciques''. The most important rulers at the time of the conquest were ''psihipqua'' Tisquesusa, ''hoa'' Eucaneme, ''iraca'' Sugamuxi and Tundama in the northernmost portion of their territories. The Muisca were organised in small communities of circular enclosures (''ca'' in their language Muysccubbun; literally "language of the people"), with a central square where the '' bohío'' of the ''cacique'' was located. They were called "Salt People" because of their extraction of salt in various locations throughout their territories, ma ...

Muisca People
The Muisca (also called Chibcha) are an indigenous people and culture of the Altiplano Cundiboyacense, Colombia, that formed the Muisca Confederation before the Spanish conquest. The people spoke Muysccubun, a language of the Chibchan language family, also called ''Muysca'' and ''Mosca''. They were encountered by conquistadors dispatched by the Spanish Empire in 1537 at the time of the conquest. Subgroupings of the Muisca were mostly identified by their allegiances to three great rulers: the '' hoa'', centered in Hunza, ruling a territory roughly covering modern southern and northeastern Boyacá and southern Santander; the '' psihipqua'', centered in Muyquytá and encompassing most of modern Cundinamarca, the western Llanos; and the ''iraca'', religious ruler of Suamox and modern northeastern Boyacá and southwestern Santander. The territory of the Muisca spanned an area of around from the north of Boyacá to the Sumapaz Páramo and from the summits to the western p ...
