The Kunene Highlands fall at the intersection of three ecoregions. These include the Zambezian, Kalahari-Highveld and Namib Karoo ecoregions. It is an arid environment that receives less than 150 mm of rain per year, and it is situated predominantly in the “Grassland with Trees” biome, interspersed with occasional “Woodland”. The Kunene Highlands contain several spectacular landscape features, most notably some incredibly impressive Tufa cliffs. Tufa is a variety of limestone formed when carbonate minerals precipitate out of water and a Tufa cliff is formed whenever calcium carbonate-saturated waters pour over a cliff, or emerge from a spring, releasing carbon dioxide and precipitating a porous calcium carbonate. The Tufa Cliff at Ekoto in Orupupa is a sight to behold. When standing at its base, this towering structure feels like a living organism of the Tolkien type. The cliff is literally heaving with rosy-faced lovebirds who find shelter in its porous structure. The unique geology of the area has also led to the creation of several little known but truly spectacular cave formations that warrant greater exploration. There is also a steep waterfall pockmarked by San rock art and legend has it that elephants slide down this waterfall as the path of least resistance from the Upper Plateau to the floor of the so-called Forgotten Valley. This is a landscape of delights and wonders that are gradually revealed to those who are patient and deserving.
