Party of three this morning. Two of us had finished riding the line. The last member of the party was in the last bit of the couloir (below the tight section) when we noticed a powder cloud shoot up. Last party member rode quickly and exited before the debris stopped in the upper apron. I spoke with another party who rode the line and the avalanche had covered most of our tracks, and the avalanche had come off the East facing slopes above the couloir. Had we been 15 minutes slower, we may have had an Aaron Rice experience. No photos, sorry.
