    Although the desert is largely unpopulated and inaccessible, there are year-round settlements at Sesriem, close to the famous Sossusvlei
    and a huge group of sand dunes, which at more than 300 meters high are among the tallest sand dunes in the world.
    The complexity and regularity of dune patterns in its dune sea have attracted the attention of geologists for decades. They still remain poorly understood.

    The dune sea of the Namib Desert: the crests of the dunes are aligned in a marked northwest-southeast orientation. The dunes act as obstacles, causing the winds to be deflected significantly to the right, in effect reorienting the southerly wind to become a southwesterly wind. A strand plain lies between the dunes and the ocean.
