** IMPORTANT ANNOUNCEMENT **

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.

More detailed information about the avalanche

Numerous naturals throughout the area related to rapid warming of snowpack. Most slopes above 40 that had not sluffed naturally would release upon skier entry. Cornice fall also observed. A very good example of spring avy potential and hazard, with wet slides with small crowns rapidly picking up speed and entraining a good deal of heavy wet snow. Small deposits of precip of April 26-27 sitting on old snow surface. Top layers did not appear to refreeze on night of Apr 27 and would release easily on old bed surface. 1 skier caught in wet slide during day and able to eventually ride out, primarily risks related to avalanche path and run out  and what that snow will be moving through and over.
