Just to throw another spanner in the works of the whole off piste safe versus not safe debate for this season in the Alps, here’s what Xavier de la Rue says about it.I was leaning towards the side of thought that the avalanche danger can change every day, but I’m not sure now.
YOUR knowledge is YOUR best survival chance ( please spread it if that can help your friends)
Watch out when you go out there, danger is not visible! The snow layer has a really weak foundation that you might not be able to see but is really tricky. It’s made of a tons of tiny small balls, which is real weak and will stay all winter. Exposed North faces are particularly something you should avoid and be aware avalanches can be triggered remotely. Get your ears open as deep “ wumpf” sounds can occur = proof of that base layer collapsing and that can trigger avalanche from flat part into close by steeper part of the mountain. thanks to Walter Steinkogler (SLF) for the pic and Johan Gaume from the SLF, swiss federal Institute for Snow and Avalanche Research based in Davos
