Smokers Bowl Triggered Avalanche

North-east aspect sz ~1-1.5 started near the peak of Smokers Bowl by a rider in our group. There was significant wind blown snow at the top of the bowl which appears to have released on a sun crust. We believe the top is ~40deg based on our slope meter. The width and runout length is not super accurate as we did not return to the top to investigate. Rider was able to exit skiers left unharmed. We certainly learned a lesson, as there was much more snow deposited here than expected from the location where we dug our pit (approx 2/3rds of the way up on the same aspect) and first rode. This wind drift was a problem which was noted in the bulletin, but we were over-confident after not seeing any signs of avalanches and from previous runs on same-aspect terrain. Hopefully others can learn from us!
