BB skiing in the past few days. Pretty impressive single-storm coverage. Skied from the top of the nose down to the base on Wednesday. Spotted a few micro wind slabs that had peeled during the storm but nothing large.

Snowpack and Avalanche Discussion

<p><span><span><span><span><span><span>A fundamental change has occurred in the past week - there is now snow in the mountains and avalanche season has begun. Over the coming days it will become patchier as sunny and lower elevation slopes melt out, but on shady, high elevation slopes there are 2-4 ft of snow and we are starting to develop the foundations of the winter’s snowpack.&nbsp;</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>We received reports of a couple avalanches during and after last weekend’s storm, including a large natural avalanche at Big Sky Resort, which is closed and currently has a snowpack similar to the backcountry (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/26695"><span><span><span><span><span><… Sky avalanche details</span></span></u></span></span></span></span></span></a><span><span><span><span><span><span>). Avalanches become less likely as we get away from the last snowfall, but can’t be forgotten about.&nbsp;</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>Throughout the fall, your safe options are either to completely avoid steep snow-covered slopes&nbsp; or to follow avalanche safety protocols by having a partner, backing out of steep terrain when signs of instability present themselves, traveling one at a time in terrain steeper than 30 degrees, and carrying rescue gear that you’ve practiced using (avalanche beacon, shovel, and probe). These rules apply regardless of the activity that you’re pursuing and apply even to crossing steep wind drifts while the surrounding terrain is bare ground..&nbsp;</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>Early-season avalanches in southwest Montana have seriously injured and buried skiers (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/accident/12/10/31"><span><span><span><stron… Incident Report</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>), caught and injured hunters (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/accident/15/11/06"><span><span><span><stron… Incident Report</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>), and resulted in tragic fatalities (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/accident/17/10/12"><span><span><span><stron… Incident Report</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>). Before heading out for the first time this season, do three things.&nbsp;</span></span></span></span></span></span></p>

<ol>
<li><span><span><span><span><span><span>Assess the condition of your gear… it didn’t fix itself over the summer (</span></span></span></span></span></span><a href="https://www.youtube.com/watch?v=Izkv4IIUmbk&amp;list=PLXu5151nmAvSpq8Ps… to video</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>)</span></span></span></span></span></span></li>
<li><span><span><span><span><span><span>Practice your avalanche rescue with your friends and backcountry partners (</span></span></span></span></span></span><a href="https://www.youtube.com/watch?v=p1xuaaSq4YU&amp;list=PLXu5151nmAvSpq8Ps… drill video</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>)</span></span></span></span></span></span></li>
<li><span><span><span><span><span><span>Look at our avalanche </span></span></span></span></span></span><a href="https://www.mtavalanche.com/workshops/calendar"><span><span><span><stro… calendar</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span> and plan to develop your skills further this year</span></span></span></span></span></span></li>

Notes

Big Sky Ski Patrol saw evidence of a natural avalanche in the closed ski area. 

From email: "saw evidence of a large avalanche that ran in 3 Forks area of The Headwaters... NE aspect in the probable start zone (could not see a crown) that likely saw significant wind loading Monday.  It ran full track and broke some branches and small trees in the runout. 

That was the only activity I saw (3 Forks is an avalanche factory with large storms).  Definite wind effect across the alpine."
