The "moving dunes" are regarded as a curiosity of nature on a European scale.

Trees will be covered by great moving dunes.

Herbert claimed in a letter to his literary agent, Lurton Blassingame, that the moving dunes could "swallow whole cities, lakes, rivers, highways."

Problems with moving dunes and desertification were brought under control in the latter 19th and early 20th centuries by large-scale plantations of grasses, bushes and fir trees.

Eventually, the rear dune has assumed dimensions similar to the former front dune which has now become a smaller, faster moving dune that pulls away with the wind.

It should be mentioned that the largest moving dune in the northwest peninsular is here that is 1.2 kilometers in length and no less than 15 meteres in height.

Replays contain visual effects such as dirt buildup on sideskirts and tires on rally stages, cars emitting smoke on rally raid stages, wind streams moving dune sand, animated waves on the Dakar seashore or the choked sound of the car bouncing on the sand dunes (Mirage Crossing).

What attracted me the most was the sight of the moving dunes, those great slow-motion waves that with their sharp, splendid geometry gave shape to the perfect solutions realized by Nature in those places where the clinging force of the biosphere, sometimes impertinent, sometimes furiously stubborn, did not impinge upon the realm of the inanimate world.
