Avalanche risk The Bottom Line

The 2018/2019 winter avalanche season has begun!

It is looking like winter in Turnagain Pass, Girdwood and through much of the state. This is thanks to a widespread snow storm on Oct. 29th that brought 8″ of snow to Girdwood, 5-8″ along the Seward Hwy through Turnagain Pass and up to a foot or more at the higher elevations. The new snow fell onto older October snow above 2,500′ but onto bare ground below this. As of Monday morning, Nov 5th, there have been three reported skier triggered avalanches. Here’s a look at the snow/avalanche events to date:

– Oct 29th, 6-8″ of snow to sea level, 12+” of snow in the Alpine, followed by cold, clear weather.

– Oct. 30th, we received our first report of a small remote triggered avalanche along the  Crow Pass Trail.

– Oct. 31st,  avalanche triggered by a skier taking a few jumps on the snow at the entrance to a line off of Pastoral Peak. This avalanche was up to 2′ deep yet only 20′ wide.  

– Nov 2nd, Wind event, 24 hours of sustained 20-30mph east winds in the Alpine

– Nov 3rd, another avalanche on Pastoral Peak, triggered intentionally by a skier performing a ski cut. This was a shallow wind slab, 3-8″ thick, 30′ wide and running full path.

These early season avalanches are good reminders that a thin snowpack can still produce a slide. They are also good reminders that a layered snowpack exists above 2,500′ in the Alpine where snow from mid-Oct existed before Oct 29th.  

Red Flags to watch for:

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

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.

Special Announcements

The CNFAIC will be issuing intermittent snow and avalanche updates as conditions warrant through mid-November. Daily avalanche forecasts are planned to begin on Thanksgiving weekend – unless we see more snow and avalanche issues before this demanding an earlier start.

As we wait for more snow to fall, we are going to provide updates and some educational reminders for the season. 

The theme for today is GET THE GEAR! from the National campaign, Know Before You Go.  New from KBYG are online training courses – check them out here – they are HIGHLY recommended as a refresher or to supplement your professional avalanche course!

Investing in avalanche rescue gear is an investment in your life and your backcountry partner’s life. If your gear is old (analog beacon) or you are new to winter backcountry travel we recomend the following when purchasing or upgrading your rescue equipment. 

Triple Antenna Beacon with multiple-burial marking

-Aluminum Probe at least 270cm long (Alaska has a deep snowpack)

-Aluminum Shovel made by a manufacturer who specialized is avalanche rescue equipment (retire your old plastic shovels)

An Avalanche Air Bag is an additional piece of safety equipment that does not replace the three essentials above, but has proven to reduce the likelihood of a full-burial.

***The BEST avalanche rescue equipment is the gear you practice with often. Remember these skills are perishable and practicing avalanche rescue once a month with your regular backcountry partners is something we should all strive for. Check out our calendar for upcoming Avalanche Courses and some free CNFAIC hosted Awareness Talks and Rescue Workshops.
