Comments:
Saw ~3ft deep crown above Bryant's couloir. Looks like it had released last night, as skiers reported seeing it on a dusk patrol last night. Saw large debris piles at the bottom of Bryants all the way down at Source Lake.

Signs of Unstable Snow

None reported

Observations

~3ft deep crown, maybe 50m wide above Bryant's Couloir (on the traverse over). See picture. Lots of graupel beneath wind stiffened snow. Approx 3-4 inches of wind slab on top of graupel as of 8 AM but growing with more wind affect as the morning progressed. Was able to ski Bryant's Couloir without any cracks, results, or avalanches. Looked like Bryant's had slid the day before, as there was debris in the couloir. Large debris pile at the bottom of the couloir above Source Lake.
