Glacial striations or striae are scratches or gouges cut into bedrock by glacial abrasion. These scratches and gouges were first recognized as the result of a moving glacier in the late 18th century when Swiss alpinists first associated them with moving glaciers. They also noted that if they were visible today that the glaciers must also be receding. Glacial striations are usually multiple, straight, and parallel, … The Khamis-Roche method2.

A good example of a roche moutonnée is shown in the image below. 2021-04-12 · Roche moutonnée, (French: “fleecy rock”) English sheepback, or sheep rock, glaciated bedrock surface, usually in the form of rounded knobs. The upstream side of a roche moutonnée has been subjected to glacial scouring that has produced a gentle, polished, and striated slope; the downstream side has been subjected to glacial plucking that has resulted in a steep, irregular, and jagged slope. roche moutonnée. A small, elongate hillock of bedrock sculptured by a large glacier so that its long axis is oriented in the direction of ice movement; the upstream side is gently inclined, smoothly rounded, but striated, and the downstream side is steep, rough, and hackly.

Roche moutonnée definition: a rounded mass of rock smoothed and striated by ice that has flowed over it | Meaning, pronunciation, translations and examples According to Charlesworth (1957), the term roche moutonnée was first used by de Saussure between 1779 and 1796 because these rocks bear a fanciful resemblance to the wavy wigs fashionable in his day and known as moutonnées, being pomaded with mutton tallow. Roche moutonnees are asymmetrical mounds or hillocks having a gradual, smooth, and striated abraded slope on one side and a comparatively craggy and steep slope on the other side. Continental glaciers being several hundred kilometers long and thick exert tremendous amount of pressure upon the ground beneath while moving.

A roche moutonnée is a geomorphic feature of mesoscale (1m to 1km of length), in the form of a boss or rocky elevation, of asymmetrical profile, having a less inclined, glacially polished and eroded, upglacier (stoss) side and a more irregular, steeper downglacier (lee) face made by plucking or quarrying of rock fragments from the basement. Jagged, rocky side of the roche moutonnee. These aspects of a roche moutonnee are very easy to see in Mack Park, Salem.

roche moutonnée(glaciated rock knob, stoss-and-lee topography) A mound-like land-form of glacial erosion, consisting of a smoothed, streamlined, up-glacier surface and a broken, shattered, lee flank, which probably results from a combination of abrasion, frost-shattering, and the plucking out of blocks by the glacier, although crushing has been suggested as a contributory mechanism.
