A Persistent Weak Layer of loose sugary faceted snow formed in mid November and is buried and causing problems. It is widespread across the Skyline on many aspects. Our pro observer Chris Magerl was prowling around the Fairview Canyon zone and documented this excellent observation.
We've seen a number of natural avalanches that broke into the November Persistent Weak Layer. Cracking and collapsing have been regular observations over the last week. This type of weak layer doesn't just heal up overnight. It's going to continue to cause problems especially during and directly any new snow storm like the current one moving through.
