 Star
Dunes
By studying a dune's physical features, even beginning students
of dune science can determine general year-to-year wind dynamics. Where
star dunes are present, an area's wind regime
is quite complex; for 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.
Star dunes can also form in bimodal wind areas such as are found in the
Central Dunefield.
