Avalanche: Hatcher Pass
Location: Marmot
Toured standard uptrack/shoulder of Marmot. Topped out via the S side and ran a couple of laps on the West face.
Avalanche Details
Large avalanche running the full length of the face of Hatch. I would estimate a crown depth of 2-3 feet. The bed surface was not the ground, so I'd assume the failure occurred with the new heavy wet snow.
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | No |
| Cracking (Shooting cracks)? | No |
Observer Comments
Observed a persistent slab avalanche running the length of the E/NE face of Hatch Peak (i.e "Face of Hatch). Observed multiple point release avalanches on the S face of Skyscraper. Very significant wind lip development on Government Peak, Peak 4068, and Hatch Peak ridge/Bald Mountain ridge.
Weather
Cloudy, ~30 degree temps, light wind. Winds picked up around 2pm to maybe 15mph with sudden snow showers.
Snow surface
Snow surface varied from wind packed/high density moist snow in the lower elevations to windcrust/sastrugi in the mid to upper elevations. We also identified a significant amount of graupel in the mid to upper elevations!
