Cirque glacier. A cirque glacier is formed in a cirque, a bowl-shaped depression on the side of or near mountains. Snow and ice accumulation in corries often occurs as the result of avalanching from higher surrounding slopes. If a cirque glacier advances far enough, it may become a valley glacier. Additionally, if a valley glacier retreats ...
A cirque (French: [siʁk]; from the Latin word circus) is an amphitheatre -like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic: coire, meaning a pot or cauldron) [1] and cwm (Welsh for 'valley'; pronounced [kʊm]). A cirque may also be a similarly shaped landform arising from fluvial erosion.
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 ...
Iceberg Cirque. Coordinates: 48.8061°N 113.7452°W. Iceberg Cirque. The Iceberg Cirque is a large cirque that has been carved out by glaciation. It is located in Glacier National Park in the U.S. state of Montana. It is near Iceberg Lake in the Many Glacier section of the park, and can be approached by a hike starting at the Many Glacier Hotel.
Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. [1] The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. [2] Types of glaciers can range from massive ice sheets, such as the Greenland ice sheet, to small ...
Pyramidal peak. The Matterhorn, a classic example of a pyramidal peak. A pyramidal peak, sometimes called a glacial horn in extreme cases, is an angular, sharply pointed mountain peak which results from the cirque erosion due to multiple glaciers diverging from a central point. Pyramidal peaks are often examples of nunataks.
Timeline of glaciation. There have been five or six major ice ages in the history of Earth over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago. Within ice ages, there exist periods of more severe glacial conditions and ...
The Cirque de Gavarnie (French pronunciation: [siʁk də ɡavaʁni]) is a cirque in the central Pyrenees, in Southwestern France, close to the border of Spain. It is within the commune of Gavarnie, the department of Hautes-Pyrénées, and the Pyrénées National Park. Major features of the cirque are La Brèche de Roland (English: Roland's Pass ...
