Although most avalanches were small (size 1-1.5), some had impressive propagation on buried weak layers (see some examples </span><a href="https://www.avalanche.ca/mountain-information-network/submissions/b87b4973-ad9d-42cc-97fa-60ab88b0ed49" target="_blank"><span class="s_B5813F7D">here</span></a><span class="s_3FE45715"> and </span><a href="https://www.avalanche.ca/mountain-information-network/submissions/c6b9ed68-c03d-4869-82fb-ee8b4f22d6da" target="_blank"><span class="s_B5813F7D">here</span></a><span class="s_3FE45715">). Last Tuesday, a notable size 3 persistent slab avalanche occurred on an east aspect at 2000 m. This avalanche was triggered by explosives and failed on the persistent weak layer that was buried on February 7th.</span></p>
