These erosional features are seen on scales of less than a metre to several hundred metres. Here at the top of the waterfall (just across the stream) is a superb example of a relatively small roche moutonnée. It can be see clearly on the far side of the falls and the shape is very obvious. 2016-06-01 The Roche Moutonnée and glacier scoured rocks are great to wander around and wonder at. Roche Moutonnée literally means “rock wigs” – in 1787 the alpine explorer H.B. de Saussure thought these groups of rounded whale-back rocks resembled the wavy wigs or “moutonées” that men wore at that time, which were slicked down with mutton tallow to keep them in place!

The roche moutonnée associated with glacial rocks of the Itararé Subgroup, near Salto, central-eastern State of São Paulo, is the only example of this kind of glacial abrasion feature known in the late Paleozoic of the Paraná Basin.Though only partially preserved, the structure still displays the characteristic shape and glacial abrasion features typical of Recent and Pleistocene 2021-04-15 · Crag and tail tends to be larger than a roche moutonnée. Crag and tail is the opposite of the roche moutonnée as the ice hits the steep resistant rock outcrop first. Once the glacier slid off the other side of the roche moutonnee, pieces of the bedrock were plucked from the rock by the glacier where they remained frozen into the ice.

Roche moutonnee diagram

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.

Roche Moutonnee are outcrops of resistant bed rock with a gentle abraded slope on what would have been the upstream side of the ice (stoss slope) and a steep rougher slope on the downstream side (lee slope). Academia.edu is a platform for academics to share research papers.
