Eureka Dunes, Death Valley National Park, California

Great Sand Dunes National Monument, Colorado Great Sand Dunes National Monument, Colorado. Complex dunes attain a maximum height of 800 feet above the floor of the valley. Sangre de Cristo Range is in the background.

Mineral-rich water evaporates and forms gypsum sand that the wind blows into huge dunes. Such dunes are constantly moving and changing their shape

The sand forms a pedestal on which the plants can survive after the dune in which they first grew blows away.
