Snow Profile Comments

Comments
<p>A dangerous persistent slab avalanche was triggered by skiers who entered the backcountry from the ridge accessed by Snowbasin&#39;s Allen Peak Tram.&nbsp; The local skiers promply reported the avalanche to the Snowbasin&nbsp;Patrol, and said that the entire Technicolor path &quot;cleaned out.&quot;&nbsp; Thankfully nobody was caught, since the dangerous avalanche traveled quite a ways out of sight&nbsp;down into Cold Water Canyon.&nbsp;</p> <p>We decided not to venture into the site&nbsp;of the avalanche because of widespread poor snowpack structure in the area and the potential of triggering another avalanche.&nbsp; Sorry that more details and photos of the avalanche are not available.</p> <p>A weak layer consisting of very loose, sugary, faceted snow from December has plagued the area all winter, and it is obviously still reactive.&nbsp; Snowpit&nbsp;tests in nearby Hell&#39;s Canyon showed moderately unstable snow and tendency for full propagation on the faceted layer.&nbsp;</p>
