The snow also may have fallen with moderate southwesterly winds in the alpine, which could have produced small wind slabs in lee features.</span></p><p class="p_CC664AAA"><span class="s_3FE45715">The additional snow could create a dangerous slab above buried weak layers. Numerous persistent weak layers exist in the snowpack. Dry snow overlies two layers composed of weak and feathery surface hoar, with the deeper layer (December 15) buried 40 to 80 cm. This layer is found most often around and below treeline. As the overlying dry snow becomes more cohesive and forms a slab, this layer has the potential to create easily-triggerable destructive slab avalanches. Where and when this will occur is tricky to predict and even professionals are scratching their heads about it. It is a good time for conservative decision-making.</span></p><p class="p_CC664AAA"><span class="s_3FE45715">Deeper in the snowpack (90 to 150 cm), a November crust is producing variable test results, from sudden fracture characters to no result. This layer is considered dormant but could be triggered where the snowpack is thin.</span></p><p class="p_CC664AAA"><span class="s_3FE45715">Please share your observations through the </span><a id='GoToAdded' href="http://www.avalanche.ca/mountain-information-network/submit" target="_blank"><span class="s_B5813F7D">Mountain Information Network</span></a><span class="s_3FE45715">.</span></p>
