Comments
<p>Remotely triggered a class 2 slide on steep aspect above Twin Lakes Pass. Was quite windy with blowing snow at the time, so very poor visibility. Got a small collapse and saw a bit of the adjacent slope had avalanched, and in a few seconds saw a sizable dust cloud at the bottom of the runout. The remotely-slide appeared to sympathetically pull out the adjacent slope. Did not get a good look at much of the bed surface, but the small part I saw showed a 30-45 cm (12-18&quot;) crown, and ran on faceted layer from the Christmas storm snow. Likely the facets in the rest of the snowpack remained intact.</p> <p>Overall not as touchy conditions as I was expecting, and this was the only slope we could get to releas along Twin Lakes Pass ridgeline. This was despite most of the leeward, east-facing terrain having been wind-loaded from westerly winds.</p> <p>It seems that the most dangerous slopes are those that have been wind-loaded. We were noticing winds well-down into drainages, so likely fresh drifts can be found well off of ridge lines.</p> <p>No photo submitted as the visibility was nearly nil at the time.&nbsp;</p>
