Great Sand Dunes National Park and Preserve, Colorado
It makes sense that the US National Park Service named this park for its 750-foot (and higher) sand dunes. The dunes are an unexpected feature of Colorado’s topography. But the towering hills of sand are part of a patchwork landscape that includes conifer forests, alpine lakes and wetlands. The 85,000-acre park and preserve even encompasses stretches of tundra at the higher elevations, where it edges up against the base of the Sangre de Cristo Mountains.
