Loess is one of the most common geologic materials found on the land surface in the Midwest. This can also be said for the lower Mississippi Valley, the Palouse district of eastern Washington, central and eastern Europe, the Ukraine of southwestern Russia and eastern China. The word itself is German in origin, and as late as the 1860s was regarded as a provincial name for deposits along the Rhine Valley. Loess, glacial history, native grasslands and productive agricultural regions are linked together across the mid-latitudes of the northern hemisphere.
