Tallest US Dunes Become Newest Park
The towering 750-foot sand dunes that rise above Colorado's arid San Luis Valley took more than a million years to form... The Great Sand Dunes National Park and Preserve includes more than 30 square miles of sand dunes, Serengeti-like grasslands, alpine forests thick with pinon and juniper, all surrounded by 14,000-foot mountain peaks... The park designation makes Great Sand Dunes the fourth national park in Colorado, joining Rocky Mountain, Mesa Verde, and Black Canyon of the Gunnison."
