|The Lairig Ghru Pass in the heart of the Cairngorm Mountains, a classic U-shaped valley. Formed during the last Ice Age which ended about 10,000 years ago. The Earth has been subject to several ice ages the first being abound 2.5 billion years ago.|
A U-shaped valley is one formed by the process of glaciation. It has a characteristic U-shape, with steep sides, and a flat bottom. Glaciated valleys are formed when a glacier travels across and down a slope,
carving the valley by the action of scouring. When the ice recedes or thaws, the valley remains, often littered with small boulders that were transported within the ice.
In the far distance, to the left of the valley, you can see the beginning of Beinn Macdui, the second highest mountain in the UK. Actually thought to be the highest until accurately measured and handed over the mantle to Beinn Nevis.
It is off course haunted both by the Old Grey Man and the the aircrew of a crashed aircraft, the remains of which still lie on the Beinn.
