Here is a really interesting article from Mcnab Snowboarding
A lot has been said about the very unstable snow conditions this year. Much like last winter there is an unstable layer of snow buried under the top layer. This year there is two unstable layers, a thin one which was from the very start of winter, then a layer of packed snow followed by another thicker layer of loose sugary unstable snow that hasn't bonded.
There have been a lot of avalanches and a lot of deaths again, which is terrible.
A lot of article have been released, and a video from St Foy showing a group caught in a large avalanche went viral.
Going off the beaten track is an amazing thing, people need to make sure they are knowledgable, are well prepared and cautious. You need to take notice of your surroundings, wear the proper avalanche rescue gear, make sure the group knows how to use it and are aware of any potential dangers on the chosen route. If in doubt, then don't go.
