Quick report

We observed two avalanches on the apron below the lost and found couloirs. We booted up the lost couloir and found very small wind slabs in various places. These wind slabs were not well bonded (Q1 in hand shears, failing during isolation) to the snow underneath, but were only a couple inches thick and already starting to facet and weaken. We skied the tracked out lost couloir and a line off birthday pass, no outward signs of instability.

2 suspected natural avalanches that probably ran Monday PM, maybe persistent facets below an old wind slab.
