Pakaraima
The Pacaraima or Pakaraima Mountains ( pt, Serra de Pacaraima, es, Sierra de Pacaraima) are a mountain range primarily in southwestern Guyana, and into northern Brazil and eastern Venezuela. Geography The range extends from west to east for over . Its highest peak is Mount Roraima at above sea level, a tepui surrounded by cliffs high. It is geologically part of the Guayana Shield and biogeographically part of the Guayana Highlands.The mountains form the divide between the Orinoco Valley to the north and the Amazon Basin to the south. They also serve as a natural boundary in the east–west direction, where they extend to form a border marker between Brazil and southeastern Venezuela and between Brazil and west central Guyana. Geology The Pacaraimas are a sandstone plateau underlain by a horizonal precambrian marine strata that arose in post-cretaceous time. Erosion of the sandstone (the Roraima Supergroup) results in dramatic escarpments, the individual remnants of whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mazaruni River
The Mazaruni River is a tributary of the Essequibo River in northern Guyana. Its source is in the remote western forests of the Pakaraima Mountains and its confluence with the Cuyuni River is near Bartica. As it descends from the Guiana Highlands the river runs south-east, past Issano, then northward to Bartica. The river is a source of alluvial gold. Sources The river takes source in the Roraima Plateau, three levels of sandstones and conglomerates, crowned by Mt. Roraima (). In Guyana, the two highest levels of the Roraima Plateau are known as Pakaraima Mountains and Merume Mountains. The source of the Mazarunu River is in the Merume Mountains. The area is one of the very few places in the world still inaccessible. In 1992, a joint expedition of the Guyana Defence Force and Welsh Guards members was unable to reach the source of Mazaruni River, even with training, finances and equipment. Course The river drops down from each Roraima plateau through three steep sided cany ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Ayanganna
Mount Ayanganna is a sandstone tepui in the Pakaraima Mountains of western Guyana, and located east of Mount Roraima. With a height of it is the easternmost tepui taller than . It is part of the Guiana Shield and Guyana Highlands. Ecology The slopes of Mount Ayanganna are covered in tall-canopy lower montane forest, up to about 1100 metres. Above this elevation, there is a series of "steps" - relatively flat plateaus separated by steeper slopes. The poorly drained plateaus support low-canopy forest or terrestrial bromeliads. The slopes support medium-canopy high-montane forest. The amphibians and reptiles of Ayanganna have been surveyed. Mount Ayanganna is fully within Guyanese territory and is surrounded by rainforest. Culture In 1966, the national flag was planted on Mount Ayanganna to commemorate Independence. It is undertaken yearly by members of the Guyana Defence Force The Guyana Defence Force (GDF) is the military of Guyana, established in 1965. It has military ba ...

Mount Roraima
Mount Roraima ( es, Monte Roraima; Tepuy Roraima; Cerro Roraima pt, Monte Roraima ) is the highest of the Pakaraima chain of tepuis (table-top mountain) or plateaux in South America. It is located at the junction of Venezuela, Brazil and Guyana. A characteristic large flat-topped mountain surrounded by cliffs 400 to 1,000 meters high. The highest point of Mount Roraima is located on the southern edge of the cliff at an altitude of 2,810 meters in Venezuela, and another protrusion at an altitude of 2,772 meters at the junction of the three countries in the north of the plateau is the highest point in Guyana. The name of Mount Roraima came from the native Pemon people. ''Roroi'' in the Pemon language means "blue-green", and ''ma'' means "great". Leaching caused by intense rainfall has shaped the peculiar topography of the summit, and the geographical isolation of Mount Roraima has made it home to much endemic flora and fauna. Western exploration of Mount Roraima did not begin unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The coastal plain, which occupies about 5 percent of the country's area, is home to more than 90 percent of its inhabitants. The plain ranges from five to six kilometers wide and extends from the Corentyne River in the east to the Venezuelan border in the northwest. The coastal plain is made up largely of alluvial mud swept out to sea by the Amazon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ireng River
The Ireng River (or Maú River, generally used in Portuguese) forms part of Guyana's western border with Brazil. It flows through the valleys of the Pakaraima Mountains for most of its length. It is the only major river in Guyana which flows from North to South, up to its confluence into the Takutu River. It is one of the northernmost tributaries of the Amazon river system. The sources of the river are in the Monte Roraima National Park, created in 1989. The larger part of the Ireng River basin forms the frontier between Brazil and Guyana. Ireng's main tributaries are the Uailan and Canã rivers on the Brazilian side and the Cacó, Dacã and Socobi rivers on the Guyanese side. All of these rivers merge with the upper and middle sections of the Ireng. Their courses are through breathtaking formations of sedimentary rocks formed by tectonic movements in ancient times. The Ireng River's waters are dark, bearing a striking resemblance to that of Rio Negro near Manaus, in Brazil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kaieteur Falls, Guyana
Kaieteur is the world's largest single drop waterfall. Located on the Potaro River in the Kaieteur National Park, it sits in a section of the Amazon rainforest included in the Potaro-Siparuni region of Guyana. It is 226 metres (741 ft) high when measured from its plunge over a sandstone and conglomerate cliff to the first break. It then flows over a series of steep cascades that, when included in the measurements, bring the total height to 251 metres (822 ft). While many falls have greater height, few have the combination of height and water volume, and Kaieteur is among the most powerful waterfalls in the world with an average flow rate of 663 cubic metres per second (23,400 cubic feet per second). Kaieteur Falls is about four and a half times the height of Niagara Falls, on the border between Canada and the United States, and about twice the height of Victoria Falls, on the border of Zambia and Zimbabwe in Africa. It is a single drop waterfall. Upriver from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Ranges Of Venezuela
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...
