Drakensberg

The Drakensberg, known in Zulu as uKhahlamba and in Sotho as Maloti, forms the eastern edge of the Great Escarpment, the massive geological feature that encircles the central plateau of Southern Africa. This escarpment stretches for more than 1,000 kilometers, beginning in the Eastern Cape Province near the Baziya mountains and Tsolo, then running northward to successively form the border between Lesotho and the Eastern Cape, Lesotho and KwaZulu-Natal, KwaZulu-Natal and the Free State, and finally KwaZulu-Natal and Mpumalanga. Continuing through Mpumalanga, it includes landmarks such as the Blyde River Canyon, Three Rondavels, and God’s Window, before extending into Limpopo Province, where it is known locally as the Klein Drakensberg near Hoedspruit, and farther west as the Wolkberg Mountains and Iron Crown Mountain—the Wolkberg being Limpopo’s highest elevation. The escarpment’s highest portion, exceeding 3,000 meters, occurs along the Lesotho–KwaZulu-Natal border. Geologically, the Drakensberg originated from steep rift valley walls formed during the breakup of Gondwana around 150 million years ago, which have since eroded inland. Massive uplifting over the past 20 million years, especially in the east, has left the plateau tilted, with the escarpment’s edge typically above 2,000 meters. The hard, erosion-resistant basalt cap gives the northern and Lesotho sections a rugged, pinnacled appearance, inspiring the Zulu name “Barrier of up-pointed spears,” while softer rocks in the KwaZulu-Natal–Free State section create a more rounded profile. The top of the escarpment is generally flat and smooth, though deep valleys carved by Orange River tributaries give the Lesotho Highlands a mountainous look. The higher elevations experience a mildly periglacial environment, and recent research indicates that lightning strikes significantly shape the summit landscapes by blasting angular debris, a process once attributed solely to frost fracturing.
