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) Diagram of glacial plucking and abrasion. The glacial history of Minnesota is most defined since the onset of the last glacial period, which

The lake is a popular destination for ice fishing. In the early 2022 fishing season an incident occurred, involving around 200 people laying on the ice sheet on Upper Red Lake. The ice sheet ruptured isolating them over a floating ice bank which separated by over 90 feet (27 m) from the contiguous ice. They had to be rescued. [2]
