Three major ice centers formed in North America: the Labrador, Keewatin, and Cordilleran. The Cordilleran covered the region from the Pacific Ocean to the eastern front of the Rocky Mountains and the Labrador and Keewatin fields are referred to as the Laurentide Ice Sheet. Central North America has evidence of the numerous lobes and sublobes.
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 ...
Glaciers in South America develop exclusively on the Andes and are subject of the Andes various climatic regimes namely the Tropical Andes, Dry Andes and the Wet Andes. Apart from this there is a wide range of latitudes on which glaciers develop from 5000 m in the Altiplano mountains and volcanoes to reaching sealevel as tidewater glaciers from ...
Blanca Glaciers - two extinct glaciers (N.& S. glacier) on Mt. Blanca. These glaciers were located at 37° 35N., longitude 105° 28W. at 12,000 feet in the Sangre de Cristo Mountain Range. These glaciers were located at 37° 35N., longitude 105° 28W. at 12,000 feet in the Sangre de Cristo Mountain Range.
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 sea level. This glaciation radically altered the geography north of the Ohio River, creating the Great Lakes.
The Athabasca Glacier is one of the six principal 'toes' of the Columbia Icefield, located in the Canadian Rockies.The glacier currently loses depth at a rate of about 5 metres (16 ft) per year [2] and has receded more than 1.5 km (0.93 mi) and lost over half of its volume in the past 125 years.
Researchers believe that the El Niño climate phenomenon influenced the melting of the Humboldt Glacier, because it causes warmer temperatures that accelerate the disappearance of tropical glaciers.
Bering Glacier is a glacier in the U.S. state of Alaska. It currently terminates in Vitus Lake south of Alaska's Wrangell-St. Elias National Park, about 10 km (6.2 mi) from the Gulf of Alaska. Combined with the Bagley Icefield, where the snow that feeds the glacier accumulates, the Bering is the largest glacier in North America.
