Crowfoot glades extended column

While at crowfoot glades we did an extended column test at 2173M on an NNE aspect at 27 degrees. Had failure at 22 strikes with full propagation along the column. Snow depth was 143cm failure at 96cm. Continuous snow fall throughout the day. Amazing skiing in trees and open slopes. Witnessed and heard approximately 8 slides in the upper alpine on 60+ degree slopes on crowfoot.
