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 ...
Horicon Marsh was created by the Green Bay lobe of the Wisconsin glaciation during the Pleistocene era. The glacier, during its advance, created many drumlins (a glacial landform) in the region, many of which have become the islands of Horicon Marsh. The marsh and surrounding Dodge County have the highest concentration of drumlins in the world.
A chronology of climatic events of importance for the Last Glacial Period, about the last 120,000 years The Last Glacial Period caused a much lower global sea level.. The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the ...
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.

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 .
Lake Maumee was a proglacial lake and an ancestor of present-day Lake Erie.It formed about 17,500 calendar years, or 14,000 Radiocarbon Years Before Present (RCYBP) as the Huron-Erie Lobe of the Laurentide Ice Sheet retreated at the end of the Wisconsin glaciation.
The major part of the Kettle Moraine area is considered interlobate moraine, though other types of moraine features, and other glacial features are common. [1] The moraine is dotted with kettles caused by buried glacial ice that calved off the terminus of a receding glacier and got entirely or partly buried in glacial sediment and subsequently ...
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 Green Bay Lobe moved across the state; also present were the Chippewa, Superior, Wisconsin Valley, and Langlade lobes.
