Many inland eolian dunes are present in North America, including vegetated (stabilized) eolian dunes of the U.S. Atlantic Coastal Plain, dunes of Laurentian Great Lakes region, dunes of the Central and Southern Great Plains, the Nebraska Sand Hills, White Sands (New Mexico), Great Sand Dunes (Colorado), dunes of the southern Colorado Plateau, and dune fields of the Southwest Deserts.
By nature, ergs are very active. Smaller dunes form and migrate along the flanks of the larger dunes and sand ridges. Occasional precipitation fills basins formed by the dunes; as the water evaporates, salt deposits are left behind. Individual dunes in ergs typically have widths, lengths, or both dimensions greater than 500 m (1,600 ft). [2]
These landforms grow from snow, sand, and/or dust in areas where wind patterns trap particles. For example, the Great Sand Dunes in Colorado grow as sand blown from a wide plain is deposited against the edge of the Sangre de Cristo mountains. Some depositional landforms include dunes, barchan dunes, ripple marks, and loess.
