The elevated plateaus between these ranges are semiarid and inhospitable, and are covered with extensive saline basins, which become lagoons in the wet season and morasses or dry saltpans in the dry season.
The rest of the water of the Taukhe, known in its middle course as the Okavango, is lost in a system of swamps and saltpans which formerly centred in Lake Ngami, now dried up. Farther south the Limpopo drains a portion of the interior plateau but breaks through the bounding highlands on the side of the continent nearest its source.
Outside of the suburb there are saltpans, most of the proceeds of which are exported to Galicia.
