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

I was skinning up bachelor on Thursday the 27th and a friend pointed out what appears to be a slide.  We figured it was the warm weather that may have caused a cornice to break and cause a slide.  The slide was on the South Ridge leading up to the top of Broken Top.  Just above the tree line in what I would call bowl one.  It was East to South East facing meaning it got a lot of sun.  The location I put on the map is my best guess.  I saw the slide when I was up on Saturday as well.
