Comments
On wind-loaded slopes facing northwest through east where the PWL exists, we traveled with a Considerable avalanche danger where human-triggered avalanches are likely. We avoided being on, adjacent to, or underneath wind-loaded slopes steeper than 30°. Several pit tests indicated an unstable structure with a strong slab on top of weak facets. Outside of wind-drifted terrain, the danger was Moderate where human-triggered avalanches are possible.
Photos:
1. Scrubby, low-elevation conditions
2. Wind-drifting above 7500'
3. Cracking on wind-drifted slopes
4. General snowpack coverage just below 8000' on Cutler Ridge (the slope had been wind-scoured somewhat)
5. The snowpack outside of wind-drifted terrain with a prominent weak layer just underneath the Thursday/Friday storm
6. The snowpack on a wind-drifted slope at 7700' where extended column tests all produced full propagation
7. Video of extended column test for the above snowpit where the score was ECTP11 indicating an unstable structure
Video
We noticed what may have been a crown on a NE-facing wind-loaded slope just below the Skyline Ridge. Given how weak the pre-existing snowpack is and the amount of wind-loading that was occurring, if there would have been a natural avalanche, this would have been a likely spot. The photo is poor quality as it was zoomed in.
