"The shimmering, white Salt Basin Dunes cover nearly 2,000 acres, and range from heavily vegetated three-foot mounds to naked, wind-blasted sixty-foot dunes that glisten and bake in the desert sun. Those who travel here can disappear into a vast and silent landscape and ponder the powerful forces of wind and time. To visit the Salt Basin Dunes, talk with park personnel at the Headquarters Visitor Center information desk." This is a quote from the NPS borchure. This area has limited access and you have to get a key.
