The Bottom Line

2018/2019 winter avalanche season has begun!

Wednesday Nov. 7th update:

Winter is here and the snowpack is slowly forming in the mountains surrounding Girdwood and Turnagain Pass. Tonight a small storm may bring up to 6-8″ of new snow to higher elevations.  Temperatures have started to increase into the mid 30F’s near sea level and East winds are expected to be moderate (15-30mph) overnight. This new snow will be landing on a shallow snowpack, roughly 8-10″ of settled snow below 2500.’ Cold temperatures over the last 10 days have formed weak faceted snow and surface hoar. Avalanche activity over the next few days will depend on how much new snow we get and how this new snow bonds to the current surfaces. Above 2500′ there is more of a layered snowpack where rain from mid-October fell as snow in the Alpine. We have already seen a few human triggered avalanches in the Alpine which are good reminders that a thin snowpack can still produce a slide.    Here’s a recap of these recent avalanche observations:

Remember to always  consider the consequences  of an avalanche, even a small wind slab can knock a person off their feet and somewhere they don’t want to go.  If you head out into the mountains be on the look out for Red Flag warnings:  

  1. Recent avalanches
  2. Cracks in the snow that shoot out from you
  3. Whumpfing (collapsing) of the snowpack
  4. Rapid changes in weather (snow/rain/wind/temperature)

Both surface hoar and faceting old snow have been observed this week in Turnagain Pass. These could be our first persistent weak layers if we get any new snow this week.  

   

A thin sun crust was found on steep southerly aspects on Seattle Ridge as well as a thin early season snowpack.

A human triggered wind slab on a North aspect of Pastoral that was triggered on 11/4 due to moderate winds the two days prior.  

Moderate NW winds blowing snow around on Nov.2 on Sunburst

We are focusing each early season update on one of the Know Before You Go’s ‘GETS’.  Today’s GET is GET THE TRAINING!  (Know Before You Go video link in case you haven’t seen it)

 

November is Avalanche Education Awareness Month for the state of Alaska and we are excited to share some important resources to help you plan for the winter season ahead. Be sure to bookmark these links and sign-up early for classes and scholarships. We really can’t express enough how important it is to take an avalanche class and practice all the skills you learn and then refresh… and practice… and take another class… and always have the mindset that there is more to know about snow. There are a variety of courses to take in Southcentral Alaska. Check out alaskaavalancheschool.com and alaskasnow.org and alaskaguidecollective.com to find one. Use our Events Calender to find out when we are offering Free awareness classes and rescue workshops. We will be adding more events to this in the next few weeks. Avalanche.org is another a great resource for avalanche information and you can check out the National Avalanche Center Encyclopedia there at the bottom of the Education page. 

AVALANCHE EDUCATION SCHOLARSHIPS

The Friends of the CNFAIC have two scholarships dedicated to avalanche education. The funds generated to make these possible are in celebration of Rob Hamel and Amy Downing, their love and passion for the mountains, and to help others stay safe. We encourage you to read each one and apply yourself if you fit the need, or pass along to someone who could benefit.  Applications due on Dec 1st.

Rob Hamel Scholarship Fund – For recreational users and professional avalanche workers.

Amy Downing Scholarship Fund – For recreational users.

Hatcher Pass Avalanche Center offers a scholarship for Mat-Su residents: Johnny Soderstrom Memorial Scholarship Fund.

Please follow us on Facebook and on Instagram @chugachavy for more updates, photos, events and interesting avalanche related posts.
