fantastic vid! I read your book (staying alive in avalanche country) every fall in prep for winter-just the definitive guide-so many pearls in there! Frankly my life expectancy has gone up due to your work as avalanche educator.
thank you for putting these videos out! super interesting! I'd actually like to learn a little more about how some one could test the slab with a ski pole.
I agree that a lot of people still view the "Considerable" risk with less seriousness than they should. You mentioned changing the name - 8 years ago; since that time I think people still wave off the level 3 warning either consciously or subconsciously
Hey Utah Avalanche Center, I have two questions. 1) What causes weak layers to be more or less persistent? 2) What causes them to eventually stabilize?
Persistent weak layers are layers of faceted snow crystals. These facets take a long time to bond to each other which is why they make a persistent weak layer. They stabilize with time and warm temperatures. One easy way is to put a thick layer of snow on top of them so that they are insulated and do not have a strong temperature gradient. They can take weeks or even months to stabilize.
So the best-case scenario for the snowpack for the season is that theirs not much if any early snow and old man winter comes along one day and starts steadily laying down very cold snow for a month
