Janesville Glaciation

The Janesville Glaciation refers to a significant period of glacial activity that occurred in North America during the Pleistocene Epoch, approximately 25,000 to 15,000 years ago. It primarily affected areas in the Midwest, including southern Wisconsin. During this time, massive ice sheets advanced, shaping the landscape by carving out valleys and depositing sediments. As the climate warmed, the glaciers retreated, leaving behind unique landforms like moraines and kettle lakes. The Janesville Glaciation is important for understanding climate change, Earth's geological history, and the development of the region's ecosystems.
