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.
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 ...
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.
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 ...
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. Easily accessible, it is the most visited glacier in North America. [ 3 ]

Fed by deep snowfall in the Wrangell Mountains, the 53 mile (85 km) long [1] Nabesna is the longest valley glacier in North America [2] and the world's longest interior valley glacier. [3] The glacier flows from an extensive icefield which covers the northern flanks of 14,163 feet (4,317 m) Mount Wrangell, a large shield volcano.
