While warmer temperatures have helped the snow to settle, higher elevations may still hold slabs triggerable by a rider.
Watch for changing conditions as you shift elevation and aspect.
Approach ridgelines with caution. Older slabs may still react to human triggers as they sit over weak surfaces. Fresh slabs may develop over the day, as snowfall builds over the new surface crust.
On Friday slabs remained reactive to riders, producing size 1 avalanches. Depth varied from 20-50 cm depending on wind loading, and all were reported to have failed on the old, faceted snow surface.

Warm temperatures and light rain have created a variable surface crust observed to mountain top in most areas. Up to 15 cm of new snow may build fresh slabs over the crust on Sunday.
Previous southerly winds developed wind slabs on north and east facing slopes at treeline and above. These overly a variety of old wind-affected surfaces, crusts, and faceted (weak) snow crystals, which were bonding poorly. While warm conditions promote the settling of the upper snowpack, reactivity may continue at treeline and above, as the weak interfaces resist bonding.
The mid and lower snowpack consists of various old crusts and is considered well-settled and well-bonded.
