 Grand
Sand Recycling
The main dune field grows to enormous heights not only because
of a complex wind regime, but also due to
sand carried by Medano and Sand Creeks. These streams seasonally
carve out and carry sand from the east and north side of the dunefield
and re-deposit it where wind can transport it back to the dune field.
