Quick answer
What does “roche moutonnee” mean?
A geological landform: a rock hill, knob, or ridge that has been shaped by the movement of a glacier, giving it a characteristic asymmetrical shape with a smooth, sloping side (stoss side) facing the direction from which the ice advanced, and a steep, rough side (lee side) where the ice plucked away rock fragments as it flowed over.

Meaning and Definition
A geological landform: a rock hill, knob, or ridge that has been shaped by the movement of a glacier, giving it a characteristic asymmetrical shape with a smooth, sloping side (stoss side) facing the direction from which the ice advanced, and a steep, rough side (lee side) where the ice plucked away rock fragments as it flowed over.
In glaciology and physical geography, the term refers specifically to these glacially smoothed and plucked bedrock features, often occurring in groups. They serve as key evidence for past glacial activity and direction of ice flow. The term is also used metaphorically in some contexts to describe any smoothed, rounded form, though this is less common.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. Both British and American English use the same French term in glaciological contexts. Spelling may sometimes appear without the accent (roche moutonnee) in both varieties.
Connotations
Purely technical/scientific. No cultural connotations beyond its French origin.
Frequency
Identically very low in both, restricted to geology/geography textbooks, papers, and field reports.

FAQ
Frequently Asked Questions
In formal scientific writing, it is common to italicize borrowed foreign terms that are not fully anglicized. However, in many geological texts, it is so established that it is often written in Roman font.
A roche moutonnée is an erosional feature formed in solid bedrock. A drumlin is a depositional landform, made of glacial till (sediment), and is typically teardrop-shaped. Both indicate ice flow direction but are formed by different processes.
The British pronunciation is roughly 'rosh moo-ton-AY'. The American is 'rohsh moo-tuhn-AY'. The 'roche' rhymes with 'gauche', and 'moutonnée' ends with a long 'a' sound.
Almost never. It is a highly specialized scientific term. Using it in everyday talk would likely cause confusion unless you were specifically discussing glacial landscapes with someone knowledgeable.
A geological landform: a rock hill, knob, or ridge that has been shaped by the movement of a glacier, giving it a characteristic asymmetrical shape with a smooth, sloping side (stoss side) facing the direction from which the ice advanced, and a steep, rough side (lee side) where the ice plucked away rock fragments as it flowed over.
Roche moutonnee is usually academic, technical (geology, geography) in register.
Learning
Memory Aids
Mnemonic
Imagine a sheep (French 'mouton') sleeping on a rock. The glacier smoothed one side like stroking the sheep's back (stoss side) and then 'plucked' wool/rock from the other side as it flowed over (lee side), leaving the rock looking fleeced.
Conceptual Metaphor
A ROCK IS A SHEEP (from its French etymology). More technically, GLACIAL MOVEMENT IS A SCULPTOR, shaping the bedrock.
