Poor Snowpack Structure
Red Flags Comments
Poor structure continues with persistent weak layer of faceted snow roughly 1 meter down throughout travel areas. Although tests did not show signs of instability, the poor structure and recent sporadic persistant slab activity has me convinced this issue has not gone away.

Problem #1 Comments

Scary moderate. Big picture, the weak persistent layers seem widespread on north and northeast aspects above 8500 but do not seem to be reactive in stability tests.

Decreasing Danger
Problem #2 Comments

No major transport or wind slab formation noted, however, some cross loading of north aspect gullies seemed widespread today.
