Quick report

Travel on mostly southeast-southwest facing terrain today consisted of a well-consolidated and supportive snow surface that varied from a minor sun crust on south facing slopes to a thin layer (~4")  of soft decomposing powder on east-north-west facing slopes. No new wet loose activity was observed, and wet surface snow was only observed on steeper slopes facing due south after roughly 2pm. Winds were calm throughout the afternoon; no wind transport was observed and no other signs of instability noted. 

No signs of instability observed in areas travelled. Evidence of previous avalanche activity on isolated features >>48hrs, with old wet loose avalanches visible in steep south facing terrain in the alpine.

Inversion present throughout the day at lower elevations below treeline (<4500'). Calm winds and above freezing temperatures observed near treeline up to approximately 7500'.

Snowpack

A generally stable snowpack was observed. A thick layer of pencil hard snow exists at the base of the snowpack, and hand hardness generally increases with depth throughout the column at this location. A knife hard rain crust was observed 1-1.5' down from the surface, with two other minor interfaces visible between layers of rounded grains. None of these layers produced any planar results in compression tests.
