How to manage?
Identification of the problem in the field
Cornices occur on ridgelines or sharp terrain breaks and are usually easy to recognize. However, while standing on the top of cornices it is sometimes difficult to estimate their size. Cornices often break further back than expected, even onto flat terrain, and are the cause of many unexpected falls in the mountains.
Avoid travel on and below large ridge top cornices, especially during periods with drifting snow or the onset warm temperatures.
