Our Starter cursor pack with Sand Dune pointer features a hill of sand made by the wind on the coast or in a desert. To understand the nature of sand dunes you need a basic knowledge of their sands, the winds, and how these main elements work together. In real life, dunes are found wherever loose sand is windblown: in deserts, on beaches, and even on some eroded and abandoned farm fields in semiarid regions, such as northwest India and parts of the southwestern United States.
