Daniels, J.M. and Knox, J.C.  2005.  Alluvial stratigraphic evidence for channel incision during the Mediaeval Warm Period on the central Great plains, USA.  The Holocene 15: 736-747.

Alluvial stratigraphic data from the upper Republican River, southwest Nebraska, USA, provided evidence for major channel incision between c. 1100 and 800 14C yr BP that correlates with a multicentennial episode of common, widespread drought, which the authors state is associated with the Medieval Warm Period, which occurred between AD 900 and 1200.
