loess

loess
  in glacial environments there is a large amount of small, fine-grained material found in the outwash plain. Strong winds often blow out from glacial areas as the cold surface cools the air above creating high pressure. These winds carry material away and deposit it elsewhere across wide areas to form loess deposits which are easily weathered into well-drained, fertile soils. Loess is not known to be forming at present and is associated with the Pleistocene.
