Avalanche: Portage / Placer
Location: Upper Skookum G.
Skookum Valley and onto the Glacier to a high point of 4500’. Found good pockets of sheltered snow at ~3500’.
Avalanche Details
Looked like a wind slab originated just below the ridge and maybe pulled out a deeper slab mid slope. We saw a few different avalanches today but this appeared to be most recent. Other debris piles looked like wet slabs in large complex terrain running to the Valley floor. Likely from the rain/ warming event last week.
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | No |
| Cracking (Shooting cracks)? | No |
Weather
Sun glorious sun! Gap winds cranking from WNW on the high ridges. Definitely moving snow but we found plenty of areas protected from the wind.
Snow surface
4-6” soft snow on supportable crust below ~500. Crust disappears with elevation and surface varies from 8-12” soft snow to stiff wind slab. No sun effect observed.
Snowpack
No formal snowpits. Jumped on some small, steep wind loaded slopes in low and mid elevations with no results. Progressed into steeper and higher elevation terrain through the day without incident. Fun day in the sun!
More recent wind slab at ~2500’ above Skookum G.
S. Face of Explorer Peak. Likely slid during last week’s warm up/ rain event.
S. Face of Carpathian as seen from 4500’. Surface conditions did not improve above 3,500’.
Other than the crowds, it was a great day to be out in the Skookum zone! ; )
