A Persistent Weak Layer that formed in mid November (DETAILS HERE) continues to be a SERIOUS threat. The avalanche activity described above clearly shows that. Riders I've spoken with have experienced collapsing and felt the snowpack drop underneath them. Snow pit tests continue to show very unstable conditions. All the signs of danger are present. The only way to stay safe is to avoid steep slopes until things stabilize.
