Glacial history of Minnesota; Glacial period – Interval of time within an ice age that is marked by colder temperatures and glacier advances; Ice age – Period of long-term reduction in temperature of Earth's surface and atmosphere; Last Glacial Period – Period of major glaciations of the Northern Hemisphere (115,000–12,000 years ago)
Athabasca Glacier, Jasper National Park, Alberta.. A comprehensive list of glaciers in Canada began with glacial surveys by the Water Survey of Canada (WSC) from 1945 to 1980, [1] including an inventory begun for the International Geophysical Year (1957–58) and contributions to the World Glacier Inventory (WGI, now part of the World Glacier Monitoring Service) for the International ...
The Laurentide ice sheet (LIS) was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glaciation epochs, from 2.58 million years ago to the present.
Concluding a series of agreements between Canada, the United Kingdom, and the Hudson's Bay Company, Canada acquires Rupert's Land and the North-Western Territory, forming the Northwest Territories. In the aftermath of the Red River Rebellion, Manitoba is subdivided from the new territory in the area around Winnipeg , becoming Canada's fifth ...
The timeline of glaciation covers ice ages specifically, which tend to have their own names for phases, often with different names used for different parts of the world. The names for earlier periods and events come from geology and paleontology .
This occurred while the Laurentian Ice Sheet was at or south of the current Canada–US border. [1] As the ice sheet melted northward, an early Lake Agassiz covered southern Manitoba, the Minnesota and Ontario boundary country, and along the Red River south of Fargo, North Dakota. The Lockhart Phase is associated with the Herman lake stage (335 ...
The rapid retreat of the Cordilleran ice sheet is a focus of study by glaciologists seeking to understand the difference in patterns of melting in marine-terminating glaciers, glaciers whose margin extends into open water without seafloor contact, and land-terminating glaciers, with a land or seafloor margin, as scientists believe the western ...
Outflow glaciers The Andrei Icefield is a large icefield in the Boundary Ranges of the Coast Mountains in northwestern British Columbia , Canada. It is located 130 km (81 mi) northwest of the community of Stewart in Cassiar Land District .
