Below are several photos from yesterday’s active avalanche conditions. You can read reports for these, and more, on our observations page – thank you to the folks for passing on their information!
As mentioned above, we have a ‘classic’ WIND SLAB avalanche problem out in the mountains. These slabs are scattered about and vary in thickness from 10″ to 2′. The trick is, some of them sit on weak faceted snow and others do not; meaning some slabs will be reactive (avalanche if the slope is steep enough) and others will not. The best method to avoid an avalanche will be avoiding wind loaded slopes – for a while. Unfortunately, facets under a slab can take days or weeks to stabilize, patience is warranted. Another trick is finding areas that were sheltered from the wind, this is where conditions are safer, however this is difficult since the wind found its way into the trees as well.
Things to watch for:
1) Wind drifted snow, stiffer snow with a smooth rounded shape. 2) Shooting cracks (great photo sent to us below). 3) ‘Whoomphing‘

Status of riding areas across the Chugach NF is managed by the Glacier and Seward Ranger Districts, not avalanche center staff. Riding area information is posted as a public service to our users and updated based on snow depth and snow density to prevent resource damage at trailhead locations.
