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.

Written Report:
I toured to the summit of Tumalo from Dutchman parking lot. The snow surface was mostly a variety of crusts.

On the summit (7775ft, 12:30) the air temperature was 1C (34F). The clouds were scattered and the wind was light out of the NW.

No avalanche problems were present and I observed no signs of unstable snow.

Dropping into the east facing bowl, I found firm, crusty conditions. The southerly aspects were beginning to soften up and skied well.
