Nebraskan  

Definition

  • The Nebraskan (or Nebraska) is the first glacial stage of the Early Pleistocene in North America, equivalent to the Günz ; from the state of Nebraska (local term). The Pleistocene prior to the Illinoian stage (the Pre-Illinoian) had previously been subdivided into the Nebraskan, Aftonian, Kansan, and Yarmouthian stages (ages). However, detailed studies of these stages revealed that the assumptions and criteria on which they were defined proved to be wrong to such a point that these stages became meaningless in terms of the actual glacial–interglacial record.
