Avalanche: Summit
Location: Tenderfoot
Skinned up tenderfoot ridge skied the front side trees, lots of tracks down from tree line, no tracks at upper elevations, lots of “fat” places that looked like could be problem wind slabs.
Avalanche Details
Observed two older avalanches, one smaller slide at ridgeline below a cornice lookers left from tenderfoot in extreme terrain. Looked to be a shallow wind slab. Also a small slide on a north facing indicator slope a few hundred feet about lake level. Looked to be a soft wind slab with a 2 foot crown, bed surface was november rain crust. Observed tracks into and out of it, probably a ski cut triggered slide.
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | Yes |
| Cracking (Shooting cracks)? | Yes |
Observer Comments
Unfortunately my route took me into micro avalanche terrain, due to the small slope and lack of terrain trap I felt it appropriate to jump around above the most likely trigger point before committing to the slope adjacent to slide mentioned above. Got a super small collapse and a 5 foot crack but no further propagation or movement.
Weather
15 degrees, no wind, sunshine on the other side of the valley.
Snow surface
Settled powder with between .5 and 3 inches of surface hoar/facets to watch next time it snows, facet depth decreased with elevation. Variable wind blown snow above tree line, looked like prevailing winds were from the north.
Snowpack
November rain crust was ubiquitous, about two feet down.
Surface hoar at tree line (beer can for scale only)
Likely ski cut triggered avalanche on the out track.
