RISS-WRM INTERGLACIAL STAGE

major division of Pleistocene time and deposits (1,600,000 to 10,000 years ago) in Alpine Europe. The Riss-Wrm Interglacial Stage, a period of relatively moderate climatic conditions, followed the Riss Glacial Stage and preceded the Wrm Glacial Stage, both periods of deteriorating conditions. The Riss-Wrm is correlated with the Eemian Interglacial Stage of northern Europe and the Ipswichian Interglacial Stage of Great Britain. It is broadly equivalent to the Sangamon Interglacial Stage of North America. In the Alps, the Riss-Wrm is represented by the Moosburg Gravels.
