The Wolkberg is a mountain range in Tzaneen, Limpopo Province, South Africa. It is a northern termination and a subrange of the Drakensberg mountain range which lines up from Eastern Cape, Lesotho, Kwazulu Natal and Mpumalanga. At 2200m (7200ft) above sea level, it is the highest mountain range in Limpopo, together with the Iron crown mountain. Its Meteorological significance is that it brings along cold fronts and is a source of cold winters throughout the Limpopo province, the cold front gets transferred from greater Drakensberg mountains in Kwazulu Natal all the way to the Wolkberg. Without the Wolkberg, Limpopo will not experience cold winters at all . The range extends for about 30 km (19 mi) in a NW/SE direction north of Sekhukhuneland. The nearest towns are Haenertsburg and Tzaneen.

Physiography

The range forms a high plateau reaching up to 2126 m in height at the Ysterkroon, its highest point. Other conspicuous peaks are 2050 m high Serala, [1] 1838 m high Mamotswiri, 1667 m high Magopalone and 1611 m high Selemole.

The Wolkberg is the source of many small mountain streams, as well as the Mohlapitse [2] and the Ga-Selati River, tributaries of the Olifants River. [3]

Ecology

Weather can change very fast from clear skies to becoming misty, with the highest reaches enveloped in clouds. Hence the name of the range, meaning "Cloud Mountain" in Afrikaans. The Wolkberg is rugged, with rocky shoulders and deep humid gorges. There are rare plant and animal species in these areas. Species such as the Wolkberg Zulu (Alaena margaritacea), the Wolkberg aloe (Aloe dolomitica), Wolkberg cycad (Encephalartos dolomiticus), the Wolkberg widow (Dingana clara) and the Wolkberg sandman (Spialia secessus), have been named after these mountains. Some species like the critically endangered butterfly Lotana blue (Lepidochrysops lotana) are only known from the Wolkberg area. [4]

The Wolkberg Wilderness Area is a protected area located in the range. [5]

Geography of South Africa Overview of the geography of South Africa

South Africa occupies the southern tip of Africa, its coastline stretching more than 2,850 kilometres from the desert border with Namibia on the Atlantic (western) coast southwards around the tip of Africa and then northeast to the border with Mozambique on the Indian Ocean. The low-lying coastal zone is narrow for much of that distance, soon giving way to a mountainous escarpment that separates the coast from the high inland plateau. In some places, notably the province of KwaZulu-Natal in the east, a greater distance separates the coast from the escarpment. Although most of the country is classified as semi-arid, it has considerable variation in climate as well as topography. The total land area is 1,220,813 km2 (471,359 sq mi). It has the 23rd largest Exclusive Economic Zone of 1,535,538 km2 (592,875 sq mi).

Great Escarpment, Southern Africa Major topographical feature in southern Africa

The Great Escarpment is a major topographical feature in Africa that consists of steep slopes from the high central Southern African plateau downward in the direction of the oceans that surround southern Africa on three sides. While it lies predominantly within the borders of South Africa, in the east it extends northward to form the border between Mozambique and Zimbabwe, continuing on beyond the Zambezi River valley to form the Muchinga Escarpment in eastern Zambia. In the west, it extends northward into Namibia and Angola.

It is named for the 19th century Pulana chief, Maripe Mashile, whose tribe used the mountain as a stronghold. Some infrastructure and roads were built in the 1950s to service a military radar station.

Current amenities include self-catering accommodation, a bush camp with log cabins beside a stream, farmhouses serving as guest houses, and a camp for school outings.
