Term
Cornice
An overhanging snow formation created by wind deposition.
GLOSSARY · Mountain literacy & safety vocabulary
Cornices form on ridges where wind deposits snow over the lee side, building a lip that hangs over the slope. They can break off unexpectedly, both under a rider standing on top and onto people below.
Context and distinction
A cornice can look like solid ground from above. Riders treat the edge as unstable and keep well back from it.
