This soil has a characteristic called vertical cleavage which makes it easily excavated to form cave dwellings, a popular method of making human habitations in some parts of China. In several areas of the world, loess ridges have formed that are aligned with the prevailing winds during the last glacial maximum.
These are called "paha ridges" in America and "greda ridges" in Europe.
Even well managed loess farmland can experience dramatic erosion of well over 2.5 kg /m per year.
The largest deposit of loess in the United States, the Loess Hills along the border of Iowa and Nebraska, has survived intensive farming and poor farming practices.
Because these floodplains consist of sediment containing a high content of glacially ground flour-like silt and clay, they were highly susceptible to winnowing of their silts and clays by the wind.
Once entrained by the wind, particles were then deposited downwind.
Loess often stands in either steep or vertical faces.
Because the grains are angular, loess will often stand in banks for many years without slumping.
