Avalanche Details

Magnum, west aspect, 3300' at crown
This was an investigation into a skier triggered avalanche reported the previous day which you can read about in 1/5 observations.
HS 200cm
The crown and flanks varied from 40-130cm in depth.
It appeared the fracture plane was a layer of 0.5-3mm advanced facets sitting atop a crust. We suspect this crust was from the Dec. 9th warm rain event. The bed surface was pencil hard.
HS-ASu-R2-D2
