It is called a crevasse.
crevasse
A moving mountain glacier can carve a U-shaped valley. As the glacier moves downhill, it erodes the sides and bottom of the valley, creating a distinctive U-shaped cross-section. The glacier's immense weight and motion combined with erosion from the ice can shape the landform over time.
A stream shaped valley is usually 'V' shaped. A glacier formed valley is usually 'U' shaped.
The shape of a valley carved by a glacier is U shaped. A valley carved by a river is V shaped.
a funnel shaped vent at the top of a volcano is a crater
A Fissure is a V shaped break in a galcier

The glacier was huge.A v-shaped valley is a valley that was shaped by a glacier.

When the glacier is moving down the side of the valley it scrapes of the rocks. The grinding changes the shape of the valley so that it is rounded.
A Cirque
The opening is called an estuary.
A stream shaped valley is usually 'V' shaped. A glacier formed valley is usually 'U' shaped.
The opening may have a crater, more technically called a "caldera."

It is caused by a glacier.
