Great Sand Dunes Wilderness
Century after century, streams, creeks, melting snows, and flash floods brought bits of rock that became sand grains out of the mountains and to the valley floor. When sand lay exposed, southwesterly winds began the slow process of bouncing the grains toward the low curve of the Sangre De Cristo Mountains where they piled up to become the Great Sand Dunes. Reaching heights of 700 feet, these are the tallest dunes in North America, and the sight of them lying at the very foot of the snow-clad Sangres can be a bit unsettling at first. This is the only Wilderness defined as a saltbush-greasewood ecosystem, with hardy plants that include blowout grass, Indian ricegrass, scurfpea, and prairie sunflower.
