Avalanche: Hatcher Pass
Location: Upper Glades/Japanese Trees
Toured from the upper Japanese Trees parking lot to 3200 ft. Conditions were thin and powdery until around 2500 ft, where snow depth increased significantly.
Avalanche Details
The avalanche slid on the wind-loaded NE wall of a steep gully. It could have been natural, or remotely triggered by a party riding the ridge above.
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | No |
| Cracking (Shooting cracks)? | Yes |
Observer Comments
We observed shooting cracks roughly 1 ft deep and 3-10 ft long on E-NE aspects above tree line. While descending, I triggered a soft slab release on a steep NE facing rollover. It propagated 10 ft wide and ran 15 ft.
Snow surface
Loose powder from the road to around 2,900 ft, where SW winds produced patchy un-supportable wind crust on prominent terrain features.
Snowpack
Very thin from the road to tree line, where the snowpack deepened rapidly with elevation. At 2700 ft the snow depth was 37 in.
