Initial plucking a long way from the crest implies slow sliding velocities and/or Roche moutonnées consist of a hill of rock, often with a smooth, often low angle slope on one side, and a steeper and jagged slope on the other side. The side that is smooth and relatively low angle is the side the glacier was flowing from, and the a steep and sometimes jagged side is the direction the ice was moving (Figure 17.21, left). Crag and tail is the opposite of the roche moutonnée as the ice hits the steep resistant rock outcrop first.
Roche moutonnée. This is a French expression that refers to rocky outcrops in glaciated landscapes, which are round on one side and irregular on the other. The ice has rounded and striated the upstream or “stoss” end (a German expression) and passed over or plucked away at the lee side.

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.
