Brandberg Mountain


The Brandberg is Namibia's highest mountain.

Location and extent

Brandberg Mountain is located in former Damaraland, now Erongo, in the northwestern Namib Desert, near the coast, and covers an area of approximately 650 km². With its highest point, the Königstein , standing at above sea level and located on the flat Namib gravel plains, on a clear day 'The Brandberg' can be seen from a great distance. There are various routes to the summit, the easiest being up the Ga'aseb river valley, but other routes include the Hungurob and Tsisab river valleys. The nearest settlement is Uis, roughly 30 km from the mountain.
The core area of was declared a National Monument in 1951.

Origin of name

The name Brandberg is Afrikaans, Dutch and German for Burning Mountain, which comes from its glowing color which is sometimes seen in the setting sun. The Damara name for the mountain is Dâures, which means 'burning mountain', while the Herero name, Omukuruvaro means 'mountain of the Gods'.

Geology

The Brandberg Massif or Brandberg Intrusion is a granitic intrusion, which forms a dome-shaped massif. It originated during Early Cretaceous rifting that led to the opening of the South Atlantic Ocean. Argon–argon dating yielded intrusive ages of 132 to 130 Ma. The dominant plutonic rock is a homogeneous medium grained biotite-hornblende granite. In the western interior of the massif, a 2 km in diameter body of pyroxene-bearing monzonite is exposed. The youngest intrusive rocks based on cross-cutting relations are arfvedsonite granite dikes and sills in the southwestern periphery of the Brandberg massif which crop out in the Amis valley. The arfvedsonite granites contain minerals rich in rare-earth element minerals such as pyrochlore and bastnaesite. Remnants of Cretaceous volcanic rocks are preserved in a collar along the western and southern margins of the massif. Their angle of dip increases towards the contact where clasts of country rock occur within the granite forming a magmatic breccia. The origins of the magmas that formed the Brandberg intrusion are related to emplacement of mantle-derived basaltic magma during continental break-up which led to partial melting of crustal rocks resulting in a hybrid granitic magma. Erosion subsequently removed the overburden rock. Apatite fission track dating indicates approximately 5 km denudation between 80 and 60 Ma.
An associated feature is the Doros Complex.

Rock painting

The Brandberg is a spiritual site of great significance to the San tribes. The main tourist attraction is The White Lady rock painting, located on a rock face with other art work, under a small rock overhang, in the Tsisab Ravine at the foot of the mountain. The ravine contains more than 1 000 rock shelters, as well as more than 45 000 rock paintings.
To reach The White Lady it is necessary to hike for about 40 minutes over rough terrain, along the ancient watercourses threading through the mountain. Today scientists are sure that the paintings were made by the San, who inhabited the area a long time ago. Apart from depictions of warriors or hunters a large amount of different animal paintings can be found, an indication that wildlife must have been abundant during that time.
The higher elevations of the mountain contain hundreds of further rock paintings, most of which have been painstakingly documented by Harald Pager, who made tens of thousands of hand copies. Pager's work was posthumously published by the Heinrich Bart Institute, in the six volume series "Rock Paintings of the Upper Brandberg" edited by Tilman Lenssen-Erz., IV. Umuab & Karoab Gorges, V. Naib and the Northwest, VI. Naib

Wildlife

The Brandberg is also home to some interesting desert flora. Damaraland is well known for its grotesque aloes and euphorbias and the region around the mountain is no exception. The area has many plants and trees that have an alien appearance, due in part to the extreme climatic conditions.
The area is uninhabited and wild. It is very arid and finding water can be difficult or impossible. In summer temperatures over 40 °C are routine.
Nonetheless, the Brandberg area is home to a large diversity of wildlife. The numbers of animals are small because the environment cannot support large populations, however most of the desert species that are found in Namibia are present and visitors to the area might glimpse a desert dwelling elephant or a rare black rhino.
The new insect taxon Mantophasmatodea was first discovered on this mountain in 2002.
The scorpion fauna of the Brandberg massif is probably the richest in southern Africa.

Flora of Namibia

The Brandberg lies within the Karroo-Namib floristic region and few members of the Cape flora are represented.
of 357 species was published in 1974 by Bertil Nordenstam stating that 11 taxa are endemic to the Brandberg, with a further 28 species endemic to the Kaoko element.
A large and significant group of species has a disjunction between the Karroo-Namib region in the south, and the arid parts of north-east Africa. These appear to be remnants of a hypothesised arid-track joining the two areas.
