Unfortunately many viewers of this video missed the point - i.e. didn't read Henry's Avlanche Talk's description - and got the wrong end of the stick as to who was to blame and why the video was posted in the first place. Always be prepared for any eventuality in the backcountry, but also read and educate yourself before you go ahead and make wild accusations over Facebook/Youtube etc.
As the European season gets properly underway it's important that for the second year running, poor early season snowfall mixed with a big dose of rain has left much of the snowpack weak and unstable. Once again scoring fresh tracks this winter won't be as carefree as we'd all like to imagine: the avalance danger is as real as ever.
It's well illustrated in this video from Henry's Avalanche Talk, a great resource both online and for proper avalanche safety training. Although it's shocking, along with their summary of events and analysis of the slide it can be a useful training resource. We'd advise you follow the link above and read everything that they have to say on the matter.
Although everyone involved survived, this was down to the fact that they were all properly equipped and trained, as well as able to work individually under extreme pressure. Again, read the procedure they went through and ask yourself if you could do the same.
Always be careful out there, and be sure to check out some of our top pieces of advice on avalanche safety here.
