The Brukkaros , also called Gross (Groß) Brukkaros , is a 1590 m high mountain near Keetmanshoop in Namibia . It originated around 80 million years ago towards the end of the Cretaceous Period .
The Brukkaros looks like a mighty, almost circular volcanic crater and dominant natural monument of the Keetmanshoop steppe landscape .
With a crater diameter of about three kilometers, it rises about 600 meters above the plateau. The crater floor is about 350 meters below the crater rim, which is easily accessible by hiking trails.
Emergence
“Contrary to the older view, the Groß-Brukkaros is not a volcanic ruin, but rather an erosion residue with a central intramontane basin in heavily silicified rocks in the chimney region of an Upper Cretan volcano. The Inselberg was carved out in the course of tertiary surface formation between the black and white edge step. Levels of rubble, floor and terrace are evidence of a multi-phase Quaternary relief history controlled by climatic fluctuations. The separation of the morphological units and the recording of lineaments could be recorded by processing Landsat - TM data. Neotectonic movements could be proven on the basis of water network changes and end pan morphology of the Fish River and its tributaries . "
