On faunal materials, U-series dating is usually carried out a series of analyses along a cross-section profile, which necessitates the cutting of the specimen. U-shaped valleys formed when snow gathered in pre-glaciated valleys, usually v-shaped river valley or when cirque glaciers extended down valley. Glaciers will reshape the V-shaped valley into one that is U-shaped. English. When the glacier melts, the landscape is transformed and the U-shaped valleys are clearly visible. Social Studies .

But even at the peak of the Pleistocene Glaciation, some of the higher peaks and ridges would have been exposed and not directly affected by glacial erosion. Truncated spurs are blunt-ended rock ridges which descend from the steep sides of a U-shaped valley or glacial trough. When the glacier melts, a U-shaped valley marks the spot where the snow and ice once flowed. As layers of snow built up over a period of 200 years or more, it was compressed until it turned into firn ice.
