<br>
Speaking as a Brit who climbs mountains sometimes, I fully support the<br>
above. The term when I first saw the subject was obvious to me that it<br>
is about tagging in the mountains.<br>
<br>
English borrows many words from French in mountaineering and skiing.<br>
For example Piste (the French word for a track). In English it refers<br>
exclusively to a ski run.<br>

Gully has too wide a meaning in English, and does not have the same<br>
precision of meaning as Couloir. Gully is more to do with drainage.<br>
