Avalanche Crestmas

Pit around 2100m on West aspect down from ridgeline. CTM18 sudden planar down 75 on Nov 13th weak layer. Same fracture did not propagate during ECT which was unexpected. Another Weak layer noted down 100 (probably Nov 7th weak layer). Surface snow was blower. Not much in the way of sluff, although apart from a couple of short pitches we didn't ride much steep terrain. No issues with wind affect. No other visible signs of instability. Awesome turns!
