A glaciated valley in the Altai Mountains showing the characteristic U shape. Malyovitsa U-shaped valley, Rila Mountain, Bulgaria U-shaped valley in Leh valley, Ladakh, NW Indian Himalaya. The glacier visible at the head of the valley is the last remnant of the formerly much more extensive glacier which carved it.
New York's Finger Lakes.Lying south of Lake Ontario, the Finger Lakes formed in tunnel valleys. 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.

Erosional landforms. As the glaciers expand, due to their accumulating weight of snow and ice they crush, abrade, and scour surfaces such as rocks and bedrock.The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.
Glen – Name for valley commonly used in Ireland, Scotland and the Isle of Man; Gorge – Deep chasm between cliffs; Graben – Depressed block of planetary crust bordered by parallel normal faults; Gulch – Deep V-shaped valley formed by erosion; Gulf; Gully – Landform created by running water and/or mass movement eroding sharply into soil
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.
By contrast with glacial U-shaped valleys, there is less downward and sideways erosion. The severe downslope denudation results in gently sloping valley sides; their transition to the actual valley bottom is unclear. Trough-shaped valleys occur mainly in periglacial regions and in tropical regions of variable wetness. Both climates are ...
Oxbow lake – U-shaped lake or pool left by an ancient river meander; Pendant bar – fluvial landform formed on the downstream side of a weathering-resistant protrusion; Plunge pool – Depression at the base of a waterfall; Point bar – Landform related to streams and rivers
The Amery Ice Shelf occupies a very large U-shaped valley with exposed nunataks along the flanks reaching 1500 m in elevation and total relief as high as 3000 m. Seaward of the Amery Ice Shelf, Prydz Bay shows bathymetry typical of glaciated margins with deeper water near the coast with a broad topographic basin, the Amery Depression that is ...
