In some parts of the world, windblown dust and silt blanket the land. This layer of fine, mineral-rich material is called Loess. Loess is mostly created by wind, but can also be formed by glaciers. When glaciers grind rocks to a fine powder, Loess can form. Streams carry the powder to the end of the glacier. This sediment becomes Loess. Loess ranges in thickness from a few centimeters to more than 91 meters (300 feet). Unlike other soils, Loess is pale and loosely packed. It crumbles easily; in fact, the word “Loess” comes from the German word for “loose.”
