Lo esencial

The avalanche danger remains LOW on on all aspects and elevations. While avalanches have become unlikely, they are not impossible. Small avalanches can still occur in isolated areas or extreme terrain during LOW danger. Continue to use caution and watch for unstable snow on isolated terrain features when traveling in the backcountry. It early season and numerous hard immovable objects remain exposed or just barely covered.

    The snowpack continues to slowly consolidate in most places. This settlement and consolidation combined with calm warm weather and a shallow snowpack with lots of anchors (aka snowmobile, board, ski, and knee destroying obstacles) will keep avalanche activity unlikely again today. Some unstable snow may still exist in small isolated areas where the sugary snow layers (facets) in the bottom half of the snowpack remain weak or in complex or extreme terrain or on unsupported slopes. These areas could include those tempting filled-in looking couliors or hanging snowfields with cliffs below them or some isolated areas on shaded and sheltered NW-N-NE aspects.

Avalanche Discussion

Yesterday variable conditions existed on Tamarack Peak. Snow surface conditions ranged from wet and sticky in the sun to breakable crust in areas with that get some sun to cold unconsolidated snow on shaded and sheltered N aspects. Exposed near and above treeline N-NE-E aspects held wind scoured snow surfaces. Snow coverage varied greatly by aspect as well with the northerly aspects holding 10-24 inches of snow while other aspects held much less snow. Many of the southerly aspects have completely melted out. 

Below the surface on northerly aspects the snowpack consisted of an upper layer of consolidating recent snow on top of a layer of weaker sugary snow (facets). In most areas snowpit tests targeting this weaker layer showed signs of consolidating and strengthening, but at least one location yielded results indicating that it remains weak and that fractures can travel along the weak layer.
