U-shaped valley with lake in Myklebustdalen, Nordfjord, Sogn og Fjordane, Norway. U-shaped valleys, also called trough valleys or glacial troughs, are formed by the process of glaciation. They are characteristic of mountain glaciation in particular. [1] They have a characteristic U shape in cross-section, with steep, straight sides and a flat ...
Yosemite Valley (/ joʊˈsɛməti / yoh-SEM-ə-tee; Yosemite, Miwok for "killer") is a glacial valley in Yosemite National Park in the western Sierra Nevada mountains of Central California, United States. The valley is about 7.5 mi (12.1 km) long and 3,000–3,500 ft (910–1,070 m) deep, surrounded by high granite summits such as Half Dome and ...
A tunnel valley is a U-shaped valley originally cut under the glacial ice near the margin of continental ice sheets such as that now covering Antarctica and formerly covering portions of all continents during past glacial ages. [ 1] They can be as long as 100 km (62 mi), 4 km (2.5 mi) wide, and 400 m (1,300 ft) deep.
A map of the world during the Last Glacial Maximum. During the LGM, valley glaciers in the southern Andes (38–43° S) merged and descended from the Andes occupying lacustrine and marine basins where they spread out forming large piedmont glacier lobes. Glaciers extended about 7 km west of the modern Llanquihue Lake, but not more than 2 to 3 ...
This is a list of glaciers existing in the United States, currently or in recent centuries. These glaciers are located in nine states, all in the Rocky Mountains or farther west. The southernmost named glacier among them is the Lilliput Glacier in Tulare County, east of the Central Valley of California.
Glenmalure (Irish: Gleann Molúra) [2] is a 20-kilometre long U-shaped glacial valley in the Wicklow Mountains in Ireland. [1] Glenmalure is an important base for climbing in the Wicklow mountains, and particularly accessing the massif of Lugnaquilla, and contains one of the earliest An Óige youth hostels in Ireland.
Cirque. 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 ...
Alpine glaciers form on the crests and slopes of mountains. A glacier that fills a valley is called a valley glacier, or alternatively, an alpine glacier or mountain glacier. [9] A large body of glacial ice astride a mountain, mountain range, or volcano is termed an ice cap or ice field. [10]
