A long narrow glacier that forms between mountains is called a valley glacier. These glaciers flow down valleys, eroding the surrounding landscape as they move. Valley glaciers are common in mountainous regions around the world.
Glacial Trough (U-shaped valleys) - Flat-bottomed valley with steep sides produced by the erosion of the floor and sides of the valley by an alpine glacier as its sediment abrades while the glacier flows downhill. On the topographic maps they are recognized by closely spaced contours along the valley sides and widely spaced contours on the valley floor.Hanging Glacial Troughs - Formed when the down-cutting erosion of the main valley glacier exceeds that by the tributary glacier. The tributary glacier flows onto the main glacier and thus has an erosional base level of the elevation of the main valley glacier. After melting, the lower portion of the tributary glacial trough is then left hanging above the main floor of the glaciated valley. On maps they are recognized by more widely spaced contours across a stream in the upper portion than in the lower portion (where the modern stream cascades into the main valley below).
Valley glaciers typically flow down valleys and do not spread out over large islands or continents. They are confined to the topography of the land and move under the influence of gravity. Ice sheets, on the other hand, can cover large landmasses like islands and continents.
A glacial valley becomes U-shaped through the process of glacial erosion. As a glacier moves down a valley, it erodes the land beneath it through a combination of abrasion and plucking. Abrasion occurs when the glacier grinds and sculpts the valley walls and floor, while plucking involves the glacier picking up and removing rock fragments. Over time, these erosional processes create a deep and wide valley with steep, straight sides characteristic of a U-shape.
A U-shaped valley is a geological formation formed by the erosive action of a glacier. Ice moving downhill carves out a broad, U-shaped valley with steep sides and a flat bottom. These valleys are characteristic of areas that have been shaped by glacier activity.

Continental and Valley Glaciers.
The glacier was huge.A v-shaped valley is a valley that was shaped by a glacier.
The Tasman Glacier is a valley glacier. It is located in the Southern Alps of New Zealand and flows down the Tasman Valley. Valley glaciers form in mountainous regions and flow along valleys carved by rivers.

The shape of a valley carved by a glacier is U shaped. A valley carved by a river is V shaped.
A stream shaped valley is usually 'V' shaped. A glacier formed valley is usually 'U' shaped.
The center of a valley glacier moves the fastest due to reduced friction from surrounding valley walls and terrain. This faster flow in the center can cause the glacier to stretch and crack, creating crevasses.
