Löss

All those tracts of löss which occur within the valleys proper come under the designation of valley-löss, while the term “hill-löss” is applied to those masses which are less closely connected with the valleys, and sometimes extend over plateaux and hilly ground between separate drainage-areas.

Among the mountains of middle Germany, and along the north border, there have been found two distinct deposits of löss separated by a weathered zone.

In northern China, the Löss Plateau dates back at least two million years and consists of alternating layers of löss and soil.
