Problem #2 Comments

Found an under represented weak layer of mixed forms containing buried NSF below the 3/18 dust layer crust. Suspect this was the weak layer for a few of the avalanches on high N-NE over the past few days. Likely to become more reactive with a rapid load tomorrow. Though variable in distribution, these weak little guys don't know that its early spring and aren't to be trusted. If the storm pans out I think we're looking at a decent little avy cycle in these locations.
