Dry loose which was anticipated on steeper slope angles.
Signs of Unstable Snow
Aside from those D1 wind slab, and dry loose: we skied powdery snow on north aspects generally sticking to mellow slope angles above treeline (well, one steeper angle for a short pitch with ease below it), but entering steep slope angles in treeline (aside from dry loose we felt comfortable with our decision to enter these steeper lines.) The one non-north aspect we skied was the East aspect of the Castle which was a touch of soft atop firm (again, this was where we cut a small wind slab loose.)
Observed Avalanche Problem #1:
Cut one small Wind slab off the ridge by the Castle skiing down the East face. Noticed pockets of small windslabs in exposed sections near treeline where noticeable wind deposited snow was forming (again, East aspect.) These were small and unlikely to be harmful, but perhaps good to know for ridges and terrain traps.
