Steady snowfall and wind over the past week has resulted in regular storm slab, wind slab, and dry loose avalanche activity. On Saturday size 1-2 slab avalanches were triggered naturally and by riders on a variety of aspects and elevations. The avalanches were typically 20-40 cm thick, but one 60 cm thick slab release on a surface hoar layer on a west aspect in the trees. Natural avalanche activity will decline as we leave the period of stormy weather, but the storm snow could continue to be reactive to human triggers.

30-60 cm of recent snow is beginning to settle and there is uncertainty about whether it will gain or loose strength in the coming days. There have been reports of this snow starting to be reactive in isolated sheltered terrain where a buried surface hoar layer is 30-60 cm below the surface. A sun crust can be found at similar depths on open south-facing terrain. A buried crust from the early February rain storm is now 50-100 cm below the surface. In most areas the snow has bonded to this crust, but in areas where the crust is shallowly buried it could be slower to bond. The lower snowpack is generally well settled and strong.

• Start on smaller terrain features and gather information before committing to bigger terrain.
• Be carefull around freshly wind loaded features.
• Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
