The suspected failure layers were mid-December or late-November layers near the base of the snowpack. Also avalanche control in the Line Creek area produced several size 2.5 and two size 3 avalanches that also failed on weak layers near the base of the snowpack. </span></p><p class="p_CC664AAA"><span class="s_3FE45715">A week ago in the neighboring Lizard Range, the east facing Mt Corrigan slide path produced a very large natural avalanche estimated to be a size 4.0, which took out mature timber in the path as it overran the Flathead FSR south of Corbin. </span></p><p class="p_CC664AAA"><span class="s_3FE45715"> </span></p>
