What Are U Shaped Valleys? A U-shaped Valley is an edifice of geology that has steep, high sides and a flat or rounded valley bottom. These valleys are formed by glaciation. They often contain lakes or rivers, sandtraps along a golf course, kettle lakes (water hazards), or other natural features. https://sofasandcouches-com42559.kylieblog.com/30288437/is-sectional-u-shape-as-important-as-everyone-says
