Thanks for this field report from Clark Lewis:

Hi Wayne. 
Clark Lewis here (Blackcomb volly doctor). Skied Garibaldi NE face (Warren glacier) today. 

Strong SW alpine wind above 2200m wrapping around and wind loading NE and E aspects. Triggered small size 1 slide at 2500m on thinly bridged headwall burgshrund, 15cm crown, 20m wide, ran 100m. Felt suddenly hollow as i weighted my ski. It was all fresh loading from the wind today. Below bergshrund was solid despite the loading. 

Also saw big fresh-looking crown on "the tent", a sub peak of Garibaldi, direct N aspect, approx 2400m, approx 3m crown, 100m wide, ran 300m, likely from yest or today since it wasn't yet wind loaded.
