Avalanches were released by skiers on small convex rolls with crown fractures up to 50 cm deep. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

A "convex roll" is a terrain feature with a convex shape to it. Often referred to as a "roll" because due to the shape of a convexity, when you come upon a feature like this, the terrain begins to "roll away" as you progress down the convexity. [Reference: Grant Statham, Avalanche Specialist, Parks Canada.]
