The Formation of Star Dunes

Where star dunes are present, an area’s wind regime is complex. Star dunes form only in places where wind blows from varied directions over the course of a year. At Great Sand Dunes, a large star dune complex occurs in the northeast corner of the dunefield. The tallest dune at Great Sand Dunes is 750’ (229m), and known simply as The Star Dune.
