Loess deposits are primarily composed of silt-sized particles that have been transported and deposited by the wind. These deposits are often related to glaciers in that the material can originate from glacially ground rock and sediment, which, when exposed and dried, can be picked up and transported by wind to be deposited elsewhere as loess.
