Brukkaros Mountain

Brukkaros Mountain

Brukkaros Mountain is a mountain in Karas Region, Namibia. Measuring 1,590 metres at its peak, Brukarros is located about 15 kilometres northeast of the primarily Nama community of Berseba.[1] It is over 600 metres taller than the surrounding area.

The mountain superficially resembles a large extinct volcano, in the form of a ring mountain with a diameter of about 4 km.[2] but has been formed by an explosion when rising magma met ground water and superheated it. It is formed of an indistinctly bedded red-brown microbreccia, composed of finely fragmented rocks of the Nama System that were blown out of a volcanic vent about 80 million years ago. The breccia layers slope inwards (unlike the slope around a volcanic crater), and removal of the softer upper layers by erosion has created the central hollow.[3] The hollow is drained by a stream which runs southwards through the ring mountain in a narrow valley. The route into the interior of the mountain is along this valley. At its head is a dry waterfall, over which the stream plunges down some 45 m after rain, and the river bed directly below the fall is the principal source of water.[4]

History

From 1926-1931, the National Geographic Society, in cooperation with the Smithsonian Institution, ran the Brukkaros Mountain Solar Observatory on the mountain to measure daily solar radiation.[1]
