Layer of loess
WebLoess is wind-blown silt materials. Western Iowa is known as one of the deepest accumulations of this material, in the Loess Hills. These deposits are generally both fertile and highly erodible, leading to need for careful management. As one moves away from the source, the depth thins and the texture becomes finer. WebLoess is a fine-grained unstratified accumulation of clay and silt deposited by the wind. It appears brown or yellow in color and is brought about by past glacial activities in an area. The thickness of loess deposits are just a few meters and one of their basic features is known as the ‘cat steps’.
