Wisconsinan Glaciation

Wisconsinan Glaciation was the most recent major ice age that occurred from about 85,000 to 11,000 years ago, primarily affecting North America. During this period, massive ice sheets covered large areas, including parts of Canada and the northern United States. As the climate warmed, these glaciers melted, shaping the landscape by carving valleys, creating lakes, and depositing sediment. This glaciation played a crucial role in forming the Great Lakes and influenced ecosystems, soil development, and human migration patterns. Understanding it helps us comprehend climate change's impact on Earth’s geography and climate.
