Great Sand Dunes National Park Mesh-Back Cap

The dunes protected at Great Sand Dunes National Park and Preserve were formed by a perfect combination of wind, water, and sediment. Water sources deposited large amounts of sediment and sand into the valley, while wind influenced by the Sangre de Cristo Mountains squeezed the sand into the tall dunes visible today.

Celebrate the dramatic landscape of this geologic wonder by donning our Great Sand Dunes National Park and Preserve mesh-back ball cap featuring the name of the park and an image of Star Dune, one of the most famous dunes at the park.
