Ireng River river in Brazil

The Ireng River 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. It is one of the northernmost tributaries of the Amazon river system.

Jasper Chalcedony variety colored by iron oxide

Jasper, an aggregate of microgranular quartz and/or chalcedony and other mineral phases, is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron(III) inclusions. The mineral aggregate breaks with a smooth surface and is used for ornamentation or as a gemstone. It can be highly polished and is used for items such as vases, seals, and snuff boxes. The specific gravity of jasper is typically 2.5 to 2.9. A green variety with red spots, known as heliotrope (bloodstone), is one of the traditional birthstones for March. Jaspilite is a banded iron formation rock that often has distinctive bands of jasper.

Guyana Country in South America

Guyana, officially the Co-operative Republic of Guyana, is a country on the northern mainland of South America. It is often considered part of the Caribbean region because of its strong cultural, historical, and political ties with other Anglo-Caribbean countries and the Caribbean Community (CARICOM). Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Venezuela to the west, and Suriname to the east. With an area of 215,000 square kilometres (83,000 sq mi), Guyana is the third-smallest sovereign state on mainland South America after Uruguay and Suriname.

The falls are situated amid the rolling, grass-covered hills of the Pakaraima Mountains. Orinduik Falls is a wide, multi-tiered series of cascades making it an ideal waterfall for swimming. Waterfall is approximately 25 m tall and more than 150 m wide. [1]

There are other waterfalls on Ireng River, including the approximately 100 m tall Kurutuik Falls located more than 40 km to the north, but due to hard accessibility these falls are rarely visited. [2]


Thanks to the airstrip next to the falls, Orinduik Falls is a popular tourist destination. The falls lie at the edge of the Pakaraima Mountains. There are frequent flights from Ogle Airport and Cheddi Jagan International Airport in Georgetown and most tours are combined with Kaieteur Falls.

Cheddi Jagan International Airport, formerly Timehri International Airport, is the national airport of Guyana. The airport is located on the right bank of the Demerara River in the city of Timehri, 41 kilometres (25 mi) south of Guyana's capital, Georgetown. It is the larger of the two international airports serving Georgetown with the other airfield being the Ogle Airport.

Kaieteur Falls waterfall

Kaieteur Falls is the world's largest single drop waterfall by the volume of water flowing over it. 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.

Iguazu Falls waterfalls in Brazil and Paraguay

Iguazú Falls or Iguaçu Falls are waterfalls of the Iguazu River on the border of the Argentine province of Misiones and the Brazilian state of Paraná. Together, they make up the largest waterfall system in the world. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the heart of the city of Curitiba. For most of its course, the river flows through Brazil; however, most of the falls are on the Argentine side. Below its confluence with the San Antonio River, the Iguazu River forms the boundary between Argentina and Brazil.

Athabasca Falls waterfall

Athabasca Falls is a waterfall in Jasper National Park on the upper Athabasca River, approximately 30 kilometres south of the townsite of Jasper, Alberta, Canada, and just west of the Icefields Parkway. A powerful, picturesque waterfall, Athabasca Falls is not known so much for the height of the falls, as it is known for its force due to the large quantity of water falling into the gorge. Even on a cold morning in the fall, when river levels tend to be at their lowest, copious amounts of water flow over the falls. The river 'falls' over a layer of hard quartzite and through the softer limestone below carving the short gorge and a number of potholes. The falls can be safely viewed and photographed from various viewing platforms and walking trails around the falls. Access is from the nearby parking lot, which leads off Highway 93A just northeast of the falls. Highway 93A takes off from the nearby Icefields Parkway, and crosses the falls on the way north to the town of Jasper. White water rafting often starts below the falls to travel downstream on the Athabasca River to Jasper.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
