Avalanche Details
Major natural, full depth soft slab on the Drive In, first observed at 10 AM on March 15th, 2018. The snowpack on Hiland Road continues to be very unstable, with large natural and human triggered slides expected to continue. Faceted crystals make up 50% or more of the snowpack here, and this configuration is not likely to stabilize anytime soon.
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | Yes |
| Cracking (Shooting cracks)? | Yes |
Observer Comments
Widespread cracking and collapsing continue in this area. The only likely safe terrain may be areas that have already avalanched to the ground, but it is conceivable that even these areas could re-activate if the facets have not been completely scoured out.
