Haslach glaciation

The Haslach glaciation (German: Haslach-Kaltzeit), Haslach Glacial Stage (Haslach-Glazial), Haslach Complex (Haslach-Komplex) and Haslach Ice Age (Haslach-Eiszeit) are old names for a cold time during the Pleistocene epoch. This cold period happened a long time ago, but it was not part of the main list of big icy times in the Alps.

Scientists first talked about the Haslach glaciation around 1981. They used a special place called the Haslach Gravels where the Riss meets the Iller-Lech Plateau to help describe it. People thought this cold time came after a warmer period called the Günz-Haslach interglacial and before another warmer time known as the Haslach-Mindel Interglacial.

Even though scientists used these names, they do not appear in the most recent official list from 2016 by the German Stratigraphic Commission. This shows how scientists sometimes change their ideas about Earth's history as they learn more.
