The Persistent Weak Layer of faceted snow that formed in Jan/Feb remains the biggest threat. It is buried about 3 feet deep. The recent human triggered avalanche in Jordan Canyon confirms this layer is still active. Snowpit tests continue to fail and propagate with a clean shear on the weak layer. I am hopeful that the string of quite warm days ahead will help stabilize this weak layer in the long run. However, it is possible that the warm weather may be enough to trigger a round of natural avalanches that break into this layer. The takeaway is that this is a fairly unusual situation we are in at this time of the season and people should continue to avoid those upper elevation more northerly facing slopes.
