The avalanche failed on a southwest facing slope below treeline and completely buried the skier who was successfully rescued by their party. Another noteworthy occurrence was a naturally-triggered size 3 persistent slab avalanche which failed on the mid-January surface hoar. The avalanche, which is thought to have been triggered by sloughing from above, occurred in the Monashees near Revelstoke on a northeast facing slope at 1900m. Although this avalanche occurred north of Hwy 1 just outside the South Columbia region, it points to the continued reactivity of deeper persistent slabs in isolated terrain.

Both slides likely released during the previous storm. And a similar, large avalanche was also reported on Face mountain in the Hurley Pass area.</span></p>

</style><p class="p_CC664AAA"><span class="s_AA239A9B">Thursday's storm likely resulted in another active avalanche cycle. Over the past week there has been regular storm slab and persistent slab avalanche activity, producing many large avalanches (size 2-3). Natural activity has occurred during the steady pulse of storms. Skiers have also been able to trigger smaller (size 1-1.5) storm slabs and wind slabs on small freshly loaded terrain features, as well as remotely trigger some large (size 2-2.5) persistent slab avalanches on adjacent slopes. The most recent remotely triggered avalanche failed on a layer of surface hoar down 80 cm on Tuesday. Remote triggering indicates a touchy weak layer that could take awhile to gain strength.</span></p>
