Tincan Cornice Chunk
This big chunk of cornice may have been triggered
The party that sent in the photos was unable to talk with a
in front of them that may have cut it on purpose; so, they were
unable to confirm whether or not this was intentional or not.
can be a very dangerous practice to cut cornices and should only
be done with extreme caution. Cornices can be very
unpredictable, and you could get crushed by this thousand odd
pound chuck of snow, or you could trigger a larger avalanche
above people below you. If this chunk of cornice released
unintentionally, then we should take it as a sign to use extra
caution traveling on or underneath the path of a cornice.
Reguardless of how this big heavy chunk released, cornice
releases can sometimes provide valuable information about
stability. This chunk obviously did not trigger any avalanches
as it slid down this slope. This indicates good stability for
this particular slope.
