Lower Curtis Glacier is a cirque glacier in the North Cascades in the U.S. state of Washington. Cirque glaciers are glaciers that appear in bowl-shaped valley hollows. [4] [12] Snow easily settles in the topographic structure; it is turned to ice as more snow falls and is subsequently compressed. [12]
Esker: Built up bed of a subglacial stream, forming small, string-like mounds left behind as a glacier retreats. [1] [3] Kame: Irregularly shaped mound of sediments previously deposited by falling into an opening of glacial ice. Moraine: Built up mound of glacial till along a spot on the glacier. Feature can be terminal (at the end of a glacier ...
At some point, if an Alpine glacier becomes too thin it will stop moving. This will result in the end of any basal erosion. The stream issuing from the glacier will then become clearer as glacial flour diminishes. Lakes and ponds can also be caused by glacial movement. Kettle lakes form when a retreating glacier leaves behind an underground ...
Its implications prompted a myriad of research in various branches of physical geography. In the case of the Paleogeography, this theory provided a model for understanding the evolution of the landscape. For hydrology, glaciology, and climatology as a boost investigated as studying geographic factors shape the landscape and affect the cycle.
College Fjord was discovered in 1899 during the Harriman Expedition, at which time the glaciers were named. The expedition included a Harvard and an Amherst professor, and they named many of the glaciers after elite colleges. According to Bruce Molina, author of Alaska's Glaciers, "They took great delight in ignoring Princeton."
An ice field (also spelled icefield) is a mass of interconnected valley glaciers (also called mountain glaciers or alpine glaciers) on a mountain mass with protruding rock ridges or summits. [1] They are often found in the colder climates and higher altitudes of the world where there is sufficient precipitation for them to form.
The slow and grinding movement of continental ice sheets and alpine glaciers across the landscape creates erosional landforms. Abrasion, plucking, and freeze-thaw action creates the U-shaped valley unique to glacial erosion. The intense pressure from the ice causes abrasion. This process carves striations, or grooves, into the bedrock as the ...
Terminal moraine of Wordie Glacier, Greenland Map of the Salpausselkä terminal moraines in Southern Finland. A terminal moraine, also called an end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by ...
