Pockets of wind slab were reactive to skier traffic early in the week through Wednesday, when a few natural small wind slabs up to size 1 were reported in the northern part of the region. Otherwise, no new avalanches were reported.
Alpine terrain is heavily wind affected to varying degrees on all aspects. 15-30 cm of snow and shifting winds from last weekend has formed wind slabs predominantly on southerly aspects. This recent snow is sitting a variety of old snow surfaces including a crust on all but northerly aspects, wind pressed and possibly a mixture of weak feathery surface hoar and/or sugary facets in sheltered terrain at treeline and below. Below this 50-80 cm down sits a crust that formed mid-January right to mountain top on southerly aspects and on all aspects below 1700 m. Additionally at this depth, feathery surface hoar may be found in shady sheltered areas at treeline. This surface hoar layer is reported to be most prevalent in the far southeast of the region near Manning Park but is unreactive at this time.The remainder of the snowpack is generally well-settled.
