A lack of new snow, warming temperatures and relatively little recent wind all have contributed to a shrinking and dormant snowpack.  Although conditions are relatively benign it doesn’t mean that you can’t find isolated pockets of instability in areas. Remain aware at all aspects particularly the upper and mid elevations. Extreme terrain may still harbor panels of old wind slab that have been dis-connected to residing snowfields by eroding winds.  Current conditions warrant consideration of your Risk vs. Reward. Every type of surface conditions exists out there from some soft residual powder in sheltered trees to boiler plate areas, unsupportable faceted snow, and breakable surface crusts. The plethora of obstacles and your exposure to them remain the biggest hazards, where even a small fall or slide could prove to be really dangerous.
