The Wisconsin glaciation extended from about 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred about 25,000–21,000 years ago during the last glacial maximum, also known as the Late Wisconsin in North America. The Last Glacial Period caused a much lower global ...

Glacial Lake Wisconsin 20,000 years ago with modern counties for geographical context. Glacial Lake Wisconsin was a prehistoric proglacial lake that existed from approximately 18,000 to 14,000 years ago, at the end of the last ice age, in the central part of present-day Wisconsin in the United States .
The Badger State is well known for its glacial landforms, created when glaciers spread across Wisconsin over the course of 20,000 years — from about 32,000 years ago to about 12,000 years ago ...
Scientists call this the "Wisconsin glacial episode," a cold climate period in the most recent ice age. After the glaciers reached their maximum extent around 20,000 years ago, the climate started ...

The Ice Age Trail is a National Scenic Trail covering 1,200 miles (1,900 km), following the terminal moraine of the Wisconsin Glaciation. [61] The western terminus is located in Interstate State Park, and the eastern end is in Potawatomi State Park, along the Door Peninsula. [62] The trail passes through 30 of Wisconsin's 72 counties.

No rocks from the Paleogene or Neogene period are known from Wisconsin; however, abundant Quaternary deposits can be found as a result of the last Ice Age. The most recent glacial cycle, the Wisconsin Glaciation, began about 31,500 years ago and receded from the state by around 7,000 years ago. During this time the Lake Michigan Lobe and the ...
