Loess are silt-sized particles deposited on the Earth's surface by winds. Extensive loess deposits formed during the Ice Ages in areas bordering large, continental glaciers. Paleosols are past soil horizons preserved in a geologic section, indicative of changes in variables such as temperature and precipitation. These deposits provide some of the most dramatic examples of changes in climate and the effect of processes that shape the landscape. Successive layers are often analyzed to provide a history of long term wind behavior and surface processes.
