The Central Plateau
We will begin in the north with Ovamboland and follow southward the line of the main ridge that forms the inner plateau.
Separated from the highlands of Angola by the gorges traversed by the Kunene, the rocky heights of Ovamboland rise but slowly at first above the general level, but south of the Otavi Hills in Damaraland they gradually ascend until a veritable highland system is developed with towering masses of table rocks and huge dome-shaped summits. Mount Omatako, which has an altitude of 8,500 feet, is the highest peak. Around it, but some distance from it, grouped like satellites, are numerous other imposing mountains from 5,000 to 6,000 feet in height. In the clear air of the uplands the granite pinnacles of these peaks are visible from a great distance. Huge valleys or gorges are a characteristic of this part of Damaraland. The mountain plateaux are widely extended. In the region of Windhoek several rivers have their rise. Further south the ridge falls again to a level of about 3,000 feet, and in many places is broken into by isolated ranges of manifold forms, while the lower levels are studded with stony kopjes.
The country along the eastern border consists of undulating plains and large areas of sandy land which closely resemble the Kalahari.
In all these uplands the prevailing formations are granite, or mica schist. Surface limestone occurs everywhere.
