A 900-mile coastline runs perpendicular to the border of Angola and Namibia. The cold water carried up from the antarctic by the Benguela Current meets the warm, dry air of the Namib Desert and the resulting depression forms a cold, dense fog that extends out into the sea. The currents and wind combine to produce a force pushing inexorably towards shore. These conditions led mariners to christen this seemingly desolate and inhospitable stretch of sand the Skeleton Coast.
