Soils provide a record earth system processes that leads to an understanding of the land and the dynamic processes that formed it.  An upland interfluve was investigated in a loess-mantled, pre-Illinoian glaciated landscape near Lincoln, NE.  The site retains a record of the stratigraphic, pedologic and paleo-topographic relationships of multiple depositional and soil development episodes.   Peoria-aged loess overlies a Loveland loess unit that consists largely of reworked, loess derived slope alluvium, channel-fills, rather than primary air-fall deposits.  These in turn cap a pre-Wisconsin paleosol developed in an erosional pedisediment, which overly a weathered, paleosol-capped Pre-Illinoian till.  Site morphology details a dynamic, varied landscape history.
