Located along the Atlantic Ocean coastline of central Namibia lay what is known as 'The Long Wall"; a wall of sand that meets the Atlantic head on. The dunes rise some 300 feet in height along the coast, and will eventually climb to over 1000 feet as they move further inland to form the tallest dunes on the Planet

Those massive dunes eventually blow into the Orange River, which then flows back to the coast where they are deposited at the southern end of the Country. There the Benguela Current from Antarctica washes the sand north where it eventually collides with the currents that work their way east across the Atlantic.

The collision washes the sand ashore again, at the Long Wall.
