Warm temps, along with a small amount of rain that fell last week has since refrozen. The rain/snow line climbed as high as 4,000’ during this period. As a result a stout crust formed up to ridge crests and summits. This crust has effectively locked the vast majority of the snowpack in place. Exceptions to this set up could be found in very steep shaded terrain above 4,000’ (where slabs 1-3′ in depth are sitting on a layer of weak snow) or on and below cornices that are sitting in the sun.
It is important to always be ready to make your own assessments, especially as conditions change. Use this advisory as a starting off point. If you observe or encounter something different let us know. You can submit your observations from the field by clicking HERE.
Despite a lack of avalanche activity, it is always important to learn, develop, and practice good travel habits. Expose only one person at a time to hazards, use islands of safety in steep terrain, and communicate decisions and plans within your group.
Temperatures in the past 24 hours have averaged 15 degrees F at the Sunburst station (3,812′). Winds there have been light, averaging 4 mph with a max gust of 14mph. No new precipitation has fallen.
Today expect partly cloudy skies. Temperatures at 1,000′ will approach 30 degrees F. Winds will be light out of the East. No precipitation is in the forecast for today.
The extended outlook is showing the potential for a more active pattern developing in the early part of next week. Low pressure systems tracking through the gulf of Alaska could move far enough North to bring much needed snow to the area. Keep your fingers crossed!

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.
