Accident and Rescue Summary: 

I went up to the avalanche site on 1/14/18... An obvious catch and carry, with good outcome.  The 1' to 3' deep and 70' wide avalanche on a very steep slope is small compared to the terrain it's in, and no other avalanches were apparent in the area.

Snow Profile Comments: 

Snow profile from 1/12/18 nearby, but about 600' lower in elevation than the avalanche.

Comments: 

We have limited details about a close call, with a rider and a triggered avalanche in the Tony Grove Area on 1/13/18.  We hope to hear more of the story.   If you see or trigger and avalanche in the backcountry, we'd love to hear about it.
