Simpson paths avalanche control

Avalanche control at Simpson. 12 shots and mostly no results which was very surprising as we expected results on the Dec 7 surface hoar/crust. Did get one significant size 2.5 on Simpson 1 that picked up a lot of snow in the track and ran a long distance. Lots of evidence of avalanches last 48 hours through the storm, running on Dec 7 SH and Cr. Consider these results carefully, as the weak layer exists and it seems strange it did not react well to explosives on Dec 23.
