U-shaped valleys or cirques. Not positive.
As a glacier moves through a valley, it digs deep into the walls and floor . A once-narrow valley that had a V shape becomes wider. As a glacier moves through, the valley becomes U shape .
A glacier valley typically has a U-shape, with steep sides and a flat bottom. This shape is the result of the erosion and scouring action of the glacier as it moves downhill, carving out the landscape over time.
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 U-shaped valley begins as a V-shaped river valley. If the temperature is low enough, a glacier (river of ice) forms inside the valley. As the glacier slowly moves, it scours the valley floor when the temperature rises and the glaciers melts away, a U-shaped valley is left behind.
This process is known as glacial erosion, where the moving glacier picks up rocks and soil, causing abrasion and plucking as it flows. As the glacier moves, it scratches and sculpts the underlying bedrock, forming features like cirques, arêtes, and U-shaped valleys. Over time, this process can result in significant changes to the landscape.
A 'V' shaped valley is formed by streams and water action. A 'U' shaped valley is formed by the gouging out of the valley walls by a glacier. A hanging valley is where side valleys are cut across by the main glacier. Hanging valleys often have waterfalls that fall into the main valley over a cliff.

it's a valley glacier, it moves slowly carrying debris and melted snow.

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.
When multiple glaciers start their downward flow from a single point, they create a valley glacier. This type of glacier forms as two or more alpine glaciers flow together and merge into a single larger glacier that moves down a valley. Valley glaciers can be quite large and have a significant impact on shaping the landscape.

A glacier helps to form a valley in two ways. When the glacier moves through an area, it scrapes the land and pushes dirt in front of it, making a larger and larger hole that eventually becomes a valley. Runoff from the glacier as it melts also helps, as it carries soil away from the area, digging out a valley.
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).
A glacial trough is a U-shaped valley carved out by a glacier as it moves downhill. It forms through a process called glacial erosion where the glacier scours and deepens the valley over time by plucking and grinding the bedrock beneath it. The vast weight and movement of the glacier cause it to scrape and shape the landscape into a distinctive U-shaped trough.
