On A Knife Edge
The smooth flanks of the massive red sand dune, abruptly gives way to a sharp boundary line, where the wind blown grains continue on upwards in their relentless journey, carried aloft in the hot turbulences to add yet more material to a hungry neighbouring dune standing close by. This is the Namib Desert's slow but relentless march in action, as it gains control over the Skeleton Coast in Namibia.
