As of March 30th, COAC has suspended backcountry avalanche advisories and pro observations until further notice.

On March 23rd, Governor Brown of Oregon issued Stay at Home orders for the public regarding the COVID-19 outbreak. The directives are clear in that “to the maximum extent possible, individuals stay at home or in their place of residence.” On March 27th the Deschutes National Forest issued a closure of all developed recreation sites including trailheads and snoparks. COAC is committed to supporting our community, local emergency services, and agency partners and because of this we felt it important to cease operations as we all work together to minimize the impacts and spread of COVID-19.   

This decision was not taken lightly. Aside from the need to maintain congruency with the Governors' orders, there are inherent risks with backcountry activities in alpine environments and it’s important to consider unnecessary exposure to COAC forecasters, first responders, and local medical staff in light of the current situation.

We look forward to getting back into the mountains and providing you all with the tools to recreate safely in the backcountry. Until then we thank you for your continued support and wish all our mountain community the best of health and wellness.

Observation Date/Time:
Sat, Mar 21, 2020 - 6:41 PM
Three Sisters Area
Report Type:
Snow Conditions   No Avalanche Activity  

Written Report:
We toured on east facing slopes in the vicinity of the Villard Glacier. We didn't see any signs of any avalanche problems in this terrain.

The most notable observation was how little melting had occurred on the slopes above 7200 ft. It was quite warm and most of the snow on the moraine features and below treeline was melting and softening during the day (true North seemed to be still holding cold snow). Once above the moraines we could feel a down slope wind that was transporting snow and keeping the snow surface cold. The ski conditions were variable.
