Swinehart, J. B., and R. F. Diffendal, Jr. 1987. Duer Ranch, Morrill County, Nebraska: Contrast between Cenozoic fluvial and eolian deposition. Geological Society of America Centennial Field Guide—North-Central Section, Trip 5: 23-28.
The Duer Ranch locality contains some of the finest and most easily accessible examples of different styles of alluvial cuts and fills in the Cenozoic rocks of Nebraska. It offers a unique area in which to examine the geometries and alluvial fills of several Miocene and Pliocene age paleovalleys and paleo-gullies. Good exposures of eolian volcaniclastic siltstones and a regionally important volcanic ash of the Oligocene age Brule Formation are also present at the Duer Ranch locality. In addition, Quaternary ephemeral stream development and deposits can be studied.
