</style><p class="p_CC664AAA"><span class="s_3FE45715">A natural size 3 persistent slab was observed on Saturday northwest of Valemount on a north aspect at 2500 m which failed down 50-100 cm. On Friday, a natural size 3.5 avalanche was reported southwest of Valemount on a east aspect at 2600 m. It's not certain how old it was, but it was likely triggered by a cornice or ice fall, stepped down to ground, and destroyed some mature timber. Earlier last week, several size 2.5-3.5 avalanches were triggered naturally and by explosives. This included a natural cornice triggered size 3 avalanche on a northeast aspect, an explosive triggered size 3.5 deep persistent slab that stepped down to the November crust, and a explosive triggered size 2.5 persistent slab that failed on the mid-February crust layer down 120 cm.</span></p><p class="p_CC664AAA"><span class="s_3FE45715">On Monday, the recent storm snow is expected to be reactive at higher elevations, especially in wind loaded terrain and on steep convex features. Cornices are large and may become weak with daytime warming or during stormy periods. We are in a low probability, high consequence scenario for persistent slab avalanches failing on deep buried weak layers. </span><a id='GoToAdded' href="http://www.avalanche.ca/blogs/novemberfacetsmarchlphccycle" target="_blank"><span class="s_B5813F7D">Click here for more details.</span></a><span class="s_3FE45715"> </span><a id='GoToAdded' href="http://www.avalanche.ca/blogs/lp-hc-2017march" target="_blank"><span class="s_B5813F7D">Click here for photos the avalanche cycle last week.</span></a><span class="s_AA239A9B" /></p>
