Great Sand Dunes
Located in Colorado, USA, Great Sand Dunes National Park and Preserve protects the tallest North American sand dunes. These massive formations were created by a unique combination of wind, water, and the Sangre de Cristo Mountains, which block prevailing winds to create a sheltered area for sand accumulation.
