Dig down and investigate the snowpack before committing to a line. Report your findings on the MIN.
In the alpine hard slabs sit overtop of facets. Dec 14th surface hoar to 6mm can be found in sheltered locations up to 2200m.
Be cautious of thick to thin snowpack areas being likely trigger locations. The persistent slabs have the potential to step down to the weakness at the base of the snowpack.

15-30cm of soft or dense snow (location dependent) over a generally firm mid-pack. Dec. Surface Hoar is down 40cm in isolated sheltered spots. An early season crust is down 40-100cm and decomposing. It overlies facets and depth hoar at the bottom of the snowpack but is well bridged by the mid-pack above unless found at shallow location.
No new avalanches observed. No patrol yesterday
