Quaternary (Pleistocene) Glaciations Modern Humans

0.01 to 1.8 M.Y. ago During the Pleistocene, repeated glaciations occurred, some of which covered parts of eastern Nebraska. This was the time period that many people have labeled the "Ice Age." The glacial ice that advanced from northern Canada created many of the features we see on the landscape today, such as the Great Lakes. 12,000 years BP
