Red Flags Comment
<p>They're there. No reason to step into or underneath/adjacent to avalanche terrain. Had so much fun on lower angle terrain not above 30 degrees today.</p>

I found the rain/rime crust all over neffs . It was found 50 cm underneath the new snow at 105 cm. Looked to be 1-2 mm in thickness with facets forming above and below the crust. The cohesive slab (1 Finger) to trigger the larger avalanche is sitting just underneath the rain/rime crust and directly on top of the basal facets. **Once the new snow avalanche is triggered it has a VERY HIGH chance to step to the ground creating a much larger avalanche.

Snowpack

Instability Comment
<p>A fist/4 finger slab sits on top of the rain/rime crust. If the storm slab releases/fails on the crust it could step down to weaker layers further down in the snowpack.</p> <p>Where I dug was 155 cm deep. There was 40 cm worth of basal factes at the ground. If you trigger any wind slab or new storm slab that then has enough weight (which is very likely) to step down to the ground, you are looking at a very large and unmanageable avalanche. Best to avoid steep slopes on all aspects for the next few days.</p>

Pow on top but monsters in the basement...
