Origin of Name

The name Brandberg is Afrikaans, Dutch and German for Fire 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

Intrusion
An intrusion is liquid rock that forms under Earth's surface. Magma from under the surface is slowly pushed up from deep within the earth into any cracks or spaces it can find, sometimes pushing existing country rock out of the way, a process that can take millions of years. As the rock slowly...

 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.

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. (I. Amis Gorge, II. Hungorob Gorge, III. Southern Gorges (Ga'aseb & Orabes), IV. Umuab & Karoab Gorges, V. Naib (A)and the Northwest, VI. Naib (B), Circus & Dom Gorges. Volume VII. Numas Gorge is unlikely to be published due to discontinued funding.)
