Loa River
The Loa River (Spanish: Río Loa) is a U-shaped river in Chile's northern Antofagasta Region. At long, it is the country's longest river and the main watercourse in the Atacama Desert. Course The Loa's sources are located on Andean mountain slopes at the foot of Miño Volcano. The upper Loa basin is flanked on the west by a ridge with elevations that reach above , whereas to the east lies a volcanic chain (including Aucanquilcha, Palpana and San Pedro), which separates it from endorheic basins as that of Salar de Ascotán. The river flows south on an elevated plateau from to altitude, part of the Alto Loa National Reserve, for about , to the oasis of Chiu Chiu. The upper courses of the river are at a considerable elevation above sea level and receive water from the Andes, mainly of two major tributaries: San Pedro de Inacaliri River and Salado River. The former joins the Loa near Conchi dam and reservoir and the latter about south of Chiu Chiu. The water of its uppe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Pedro De Inacaliri River
San Pedro de Inacaliri River, or called simply San Pedro River, is a List of rivers in Chile, river of Chile located in El Loa Province, Antofagasta Region. It begins at the confluence of the rivers Silala River, Silala and ''Cajón'', at an elevation over 4,000 m asl. A part of its flow is diverted (between 50 and 60 L/s) and conducted across the desert to Chuquicamata for domestic water supply. About 8 km south, the waters of the river disappear in a floodplain area to reappear 15 km downstream at the so-called ''Ojos del San Pedro'' in the form of a partially overground stream, at the eastern border of a Salt pan (geology), salt flat with a surface of 5 km2. Before discharging into Loa River, the river skirts the San Pedro (Chile volcano), San Pedro volcano, where it has carved a 100-m-deep canyon through a rhyolite lava flow.

Rivers Of Antofagasta Region
A river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscape aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pictograph
A pictogram (also pictogramme, pictograph, or simply picto) is a graphical symbol that conveys meaning through its visual resemblance to a physical object. Pictograms are used in systems of writing and visual communication. A pictography is a writing system which uses pictograms. Some pictograms, such as hazard pictograms, may be elements of formal languages. In the field of prehistoric art, the term "pictograph" has a different definition, and specifically refers to art painted on rock surfaces. Pictographs are contrasted with petroglyphs, which are carved or incised. Small pictograms displayed on a computer screen in order to help the user navigate are called '' icons''. Historical Early written symbols were based on pictograms (pictures which resemble what they signify) and ideograms (symbols which represent ideas). Ancient Sumerian, Egyptian, and Chinese civilizations began to adapt such symbols to represent concepts, developing them into logographic writing systems. Pic ...

Petroglyph
A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs, estimated to be 20,000 years old are classified as protected monuments and have been added to the tentative list of UNESCO's World Heritage Sites. Petroglyphs are found worldwide, and are often associated with prehistoric peoples. The word comes from the Greek prefix , from meaning " stone", and meaning "carve", and was originally coined in French as . In scholarly texts, a ''petroglyph'' is a rock engraving, whereas a '' petrograph'' (or ''pictograph'') is a rock painting. In common usage, the words are sometimes used interchangeably. Both types of image belong to the wider and more general category of rock art or parietal art. Petroforms, or patterns and shapes made by man ...

Geoglyph
A geoglyph is a large design or motif – generally longer than – produced on the ground by durable elements of the landscape, such as stones, stone fragments, gravel, or earth. A positive geoglyph is formed by the arrangement and alignment of materials on the ground in a manner akin to petroforms, while a negative geoglyph is formed by removing part of the natural ground surface to create differently coloured or textured ground in a manner akin to petroglyphs. Geoglyphs are generally a type of land art, and sometimes rock art. A hill figure is created on a slope, so that it can be seen from a distance. Ancient Arguably the most famous geoglyphs are the Nazca lines in Peru. The cultural significance of these geoglyphs for their creators remains unclear, despite many hypotheses. Since the 1970s, numerous geoglyphs have been discovered on deforested land in the Amazon rainforest, Brazil, leading to claims about Pre-Columbian civilizations. Ondemar Dias is accredited w ...
