U-shaped Valley – This a valley which was V-shaped but has been eroded by ice. The valley sides are steeper and the valley floor flatter after the ice melts. Hence the name U-shaped valleys.
The video below shows High Cup, a u-shaped valley in the North Pennines.
Truncated Spurs – These are spurs which have been cut through by ice, e.g. Nant Francon Valley, Snowdonia.
Hanging Valleys – These occur when glaciers at higher levels than the main valley didn’t experience such powerful erosion. Tributary streams enter the valley as waterfalls from hanging valleys.
Ribbon Lakes – These are lakes found in U-shaped valleys, e.g. Lake Windermere, Lake District.
Drumlins – These are hills shaped like eggs! (see diagram below).
The main features of a drumlin
Drumlins are blunt at one end and tapered at the other. Drumlins are found in swarms called ‘basket of eggs’ topography. This is because they look like eggs in a basket! They are formed when ice is moving forward, but is also melting. The ice deposits boulder clay and till when it comes across a small obstacle (e.g. small rock outcrop). Most material is deposition the ‘up stream’ end of the drumlin. The down stream end is shaped by the ice.
