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 ...
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 ...
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.
A less severe cold period or ice age is shown during the Jurassic-Cretaceous (150 Ma). There have been five or six major ice ages in the history of Earth over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago.
The Ice Age National Scientific Reserve is an affiliated area of the National Park System of the United States comprising nine sites in Wisconsin that preserve geological evidence of glaciation. To protect the scientific and scenic value of the landforms, the U.S. Congress authorized the creation of a cooperative reserve in 1964.
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.
Big Rock. The Foothills Erratics Train is a 580 miles (930 km) long, narrow (0.62 miles (1.00 km) to 13.7 miles (22.0 km) wide), linear scatter of thousands of typically angular boulders of distinctive quartzite and pebbly quartzite that lie on the surface of a generally north-south strip of the Canadian Prairies.
Tinley moraine, a glacial feature of Illinois & Indiana. Based on Publication 6876-12989-1-PB; The Tinley Moraine in Indiana; Allan F. Schneider; Indiana Geological Survey; Indianapolis, Indiana; undated. The Tinley Moraine is a moraine around the Lake Michigan basin in North America.
