Corrie: A round hollow in a hillside is the definition of a corrie. a corrie can also be a cirque an example of a corrie is Coire an t-Sneachda is a glacial cirque or corrie landform in the Cairngorm or Am Monadh Ruadh mountain range in the Grampian Mountains of the Scottish Highland.
arete: a arete is a sharp narrow ridge found in rugged mountains. Striding Edge is a classic scrambling route on Helvellyn, linking the summit ridge of Birkhouse Moor to Helvellyn's summit by what becomes a sharp arête. Stretches for over a mile to the Helvellyn summit plateau. The initial part of the ridge is relatively rounded and has a good path running along the right hand side. This all changes upon reaching High Spying How, which at 863 m (2,831 ft) is the highest point on the ridge
pyrimidal peak: A pyramidal peak, sometimes in its most extreme form called a glacial horn, is an angular, sharply-pointed mountaintop created by the erosion of multiple glaciers converging on a central point. the matterhorn is a mountain in the Alps on the border between Switzerland and Italy. Its summit is 4,478 meters (14,690 ft) high, making it one of the highest peaks in the Alps.
U shaped valley: A U-shaped valley or glacial trough is formed by the process of glaciation. It has a characteristic U shape, with steep, straight 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.U-valleys are found in mountainous region like the Alps, Himalaya, Rocky mountains, Scottish Highlands, Scandinavia, New Zealand and Canada.
truncated spur: A truncated spur is a geologic formation created under specific conditions which result in a ridge of land with its end cut off. It occurs when ridge spurs, which were formed in a mountainous area by river action, have been (or are still being) truncated by the action of ice or active faulting.The Devil's Point in upper Glen Dee is an example of a truncated spur in the Cairngorms.
roche mountonnee: a roche moutonnée is a rock formation created by the passing of a glacier.These erosional features are seen on scales of less than a metre to several hundred metres.Good examples of small roches moutonnees occur near Dulnain Bridge, just south of Grantown-on-Spey.
stritations: Glacial striations are scratches or gouges cut into bedrock by glacial abrasion. Glacial striations are usually multiple, straight, and parallel, representing the movement of the glacier using rock fragments and sand grains, embedded in the base of the glacier, as cutting tools.A 2,937-foot mountain located in Wilmot, New Hampshire, and Warner, New Hampshire.there are stritations on the mountainside.
ribbon lake: A ribbon lake or loch is a long and narrow, finger-shaped lake, usually found in a glacial trough.A ribbon lake may also form behind a terminal or recessional moraine, both of which also act as dams, enabling water to accumulate behind them. Examples of ribbon lakes are: Windermere, Panguipulli, Coniston Water, Lake Washington and Wastwater.
