A sharp, steed-sided ridge in an upland area. Resultant of enlargement of adjacent corries. Erosional
The classic, pyramid-shape of a mountain-top formed when three or four corries form on different sides of the mountain and erode backwards towards each other. Erosional
A great bowl-shaped hollow at the head of a glacial valley. Erosional
A rock hill shaped by the passage of ice to give a smooth up-ice side and a rough, plucked and cliff-girt surface on the down-ice side Erosional
Rock hills shaped by the passage of ice to give a smooth up-ice side and a rough, plucked and cliffed surface on the down-ice side. Erosional
A tadpole-shaped landform developed by glacial erosion of rocks on unequal resistance. Erosional
Scratch marks or grooves found on a rock surface that has experienced glacial abrasion Erosional
A small glacial valley entering a larger one someway up the side of the latter Erosional
A broad, flat bottomed valley created by glacial erosion and deposition. The erosion widened and deepened the original river valley. Erosional
A short ridge or delta-shaped fluvioglacial deposit of sorted sand and gravel found on the floor of a glacial valley. Fluvioglacial
A flat and gently sloping area of gravels, sands, silts and clays deposited beyond the snout of a glacier by meltwater issuing from it. Fluvioglacial
A river that has been forced to divide into multiple channels which interlink with each other Fluvioglacial
A low, winding ridge of fluvioglacial deposits which have been laid within sub-glacial channels, therefore found running along the floor of glacial valleys. Fluvioglacial
A two-layered deposit in a lake near to a glacial area Fluvioglacial
A ridge of sand and gravel found along the sides of a glacial valley formed from the collapse of fluviogalcial deposits in meltwater streams Fluvioglacial
A small depression usually found on the outwash plain of a glacial area and sometimes containing a small lake Fluvioglacial
Highly angular rock pieces produced by freeze-thaw weathering and found at the base of a steep or vertical cliff face. Periglacial
A light-coloured fine-grained accumulation of clay and silt particles that have been deposited by the wind Periglacial
A type of slope failure where sediments form a tongue-shaped feature due to differential downhill flow rates. Periglacial
Extensive area of large angular rock fragments in periglacial regions. Periglacial
The melting of ground ice causes subsidence and creates a very uneven surface Periglacial
Occur when water within sediments rises towards the surface and then freezes pushing those sediments upwards Periglacial
A crack in the ground formed by a narrow or thin piece of ice that measures up to 3–4 meters in length at ground level and extends downwards into the ground up to several meters. Periglacial
The appearance of lines and polygonal layouts of stones on the surface Periglacial
Occur in areas of continuous permafrost where unfrozen water beneath lakes becomes overly saturated and then expands as the permafrost advances. Periglacial
A large, extremely heavy boulder found in an area of entirely different geology Depositional
A mound of glacial debris formed into a smooth, elongated feature whose apex is skewed towards the rear (in terms of the direction of movement). Depositional
Marks the furthest point the glacier reached as it 'bulldozed' material ahead of the ice mass. Depositional
Deposits of the load carried in the middle of the glacier where two lateral moraines came together from tributary glacier Depositional
Form at the end of the glacier so they are found across the valley. They form where a retreating glacier remained stationary for sufficient time to produce a mound of material. Depositional
Only formed by glaciers that have retreated and then advance again. Depositional
Deposits of load carried at the edges of the glacier. Depositional
Till deposited over the valley floor. It has no obvious features and is to be found where the glacier ice meets the rock underneath the glacier. Depositional
