Glacial history of Minnesota. Northern Hemisphere glaciation during the last ice ages. The creation of 3 to 4 kilometres (1.9 to 2.5 mi) thick ice sheets caused a global sea level drop of about 120 m (390 ft) The glacial history of Minnesota is most defined since the onset of the last glacial period, which ended some 10,000 years ago.
The Wisconsin glaciation extended from about 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene.

A warm start to the winter season has left the Great Lakes virtually ice-free and with their lowest ice cover to kick off a new year in at least 50 years.

Some key elements are required to form lake-effect precipitation and which determine its characteristics: instability, fetch, wind shear, upstream moisture, upwind lakes, synoptic (large)-scale forcing, orography/topography, and snow or ice cover.
